Recent Longevity News for the seven days ending 7/3/13.  You should consult your doctor if you are taking any medications.

Scientists show how DHA resolves inflammation - Science Daily, 7/1/13 - "Chronic inflammation is a major factor in a wide range of problems from arthritis to cardiovascular disease, and DHA (found in fish oil) is known to temper this problem ... researchers found that macrophages (a type of white blood cell) use DHA to produce "maresins," which serve as the "switch" that turns inflammation off and switches on resolution" - See Jarrow Max DHA at Amazon.com.

Long-Term Cannabis Use May Blunt the Brain's Motivation System - Science Daily, 7/1/13 - "Long-term cannabis users tend to produce less dopamine, a chemical in the brain linked to motivation ... The researchers used PET brain imaging to look at dopamine production in the striatum of 19 regular cannabis users and 19 non-users of matching age and sex ... The lowest dopamine levels were seen in users who meet diagnostic criteria for cannabis abuse or dependence"

Lithium Reduces Risk of Suicide in People With Mood Disorders, Review Finds - Science Daily, 6/28/13 - "The authors say the drug "seems to reduce the risk of death and suicide by more than 60% compared with placebo ... Mood disorders are a leading cause of global disability. The two main types are unipolar disorder (often called clinical depression) and bipolar disorder (often called manic depression) ... People with a mood disorder have a 30 times greater risk of suicide than the general population ... there is some evidence that lithium decreases aggression and possibly impulsivity, which might be another mechanism mediating the anti-suicidal effect" - See lithium products at iHerb.

Choline Intake During Pregnancy and Child Cognition at Age 7 - Medscape, 6/28/13 - "Higher gestational choline intake was associated with modestly better child visual memory at age 7 years" - See citicholine at Amazon.com.

Specific Fish Oils May Protect Against Breast Cancer - Medscape, 6/27/13 - "The consumption of higher levels of dietary marine n-3 polyunsaturated fatty acids (PUFAs) is associated with a 14% lower risk for breast cancer than lower levels of consumption ... They found that marine n-3 PUFAs were associated with a 14% reduction in the risk for breast cancer (relative risk [RR] for highest vs lowest intake, 0.86) ... no significant association was observed for exposure to alpha linolenic acid (ALA), which is contained in some nuts and in vegetable oils. About half of the studies in the meta-analysis contained data on ALA. Both ALA and n-3 PUFAs are types of omega-3 fatty acids" - [Science Daily] - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.  Note:  Alpha linolenic acid is the plant form of omega-3 such as what's in flaxseed oil.

Could a Diet High in Fish and Flax Help Prevent Broken Hips? - Science Daily, 6/27/13 - "The study showed that higher levels of omega-3 fatty acids from both plant and fish sources in those blood cells were associated with a lower likelihood of having fractured a hip ... The study also showed that as the ratio of omega-6 fatty acids to omega-3s increased, so did the risk for hip fracture ... Inflammation is associated with an increased risk of bone loss and fractures, and omega-3 fatty acids are believed to reduce inflammation ... omega-3 fatty acids have anti-inflammatory properties and omega-6 fatty acids seem to have both anti- and pro-inflammatory effects ... women who had the highest ratio of omega-6 to omega-3 fatty acids had nearly twice the risk of hip fractures compared to women with the lowest ratios. The current typical American diet contains between 15 and 17 times more omega-6 than omega-3, a ratio that previous research has suggested should be lowered to 4-to-1, or even 2-to-1, by increasing omega-3s, to improve overall health. The primary omega-6 fatty acid in the diet is linoleic acid, which composes about 99 percent of Americans' omega-6 intake and is found in corn, soybean, safflower and sunflower oils" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Selegiline transdermal system promising for social phobia - Clinical Psychiatry News, 6/26/13 - "Twenty patients participated in this 12-week, open-label, pilot study. They were treated with the selegiline transdermal system (Emsam) at a dose of 6 mg/24 hours. They demonstrated a significant mean 7.1-point drop from a baseline score of 17.6 on the avoidance component of the Liebowitz Social Anxiety Scale, as well as a 6.6-point drop on the scale’s anxiety component, a result that just missed statistical significance ... Selegiline is an MAO-A and -B inhibitor. Its transdermal administration bypasses the GI tract and liver, thereby essentially eliminating the risks of hypertensive crisis and dietary interactions with tyramine-rich foods, which have demoted the traditional oral monoamine oxidase (MAO) inhibitors in antidepressant treatment hierarchies ... In addition to the favorable results on the Liebowitz Social Anxiety Scale over the course of 12 weeks, participants also showed statistically significant improvements on the Social Life/Leisure Activities domain of the Sheehan Disability Scale, the Clinical Global Impression Severity of Illness Scale, and the Clinical Global Impression Change Scale" - Note:  Emsam is the patch form of deprenyl (also called selegiline) which has been touted for anti-aging since around the '70's.  See deprenyl at International Anti-aging Systems.

Feeling Stressed? Oxytocin Could Help You Reach out to Others for Support - Science Daily, 6/25/13 - "The next time someone snubs you at a party and you think hiding is the solution to escape your feelings of rejection, think again. Scientists have shown that reaching out to other people during a stressful event is an effective way to improve your mood ... instead of the traditional 'fight or flight' response to social conflict where people get revved up to respond to a challenge or run away from it, oxytocin may promote the 'tend and befriend' response where people reach out to others for support after a stressful event. That can, in turn, strengthen social bonds and may be a healthier way to cope ... 100 students were administered either oxytocin or a placebo via a nasal spray, then subjected to social rejection ... In a conversation that was staged to simulate real life, researchers posing as students disagreed with, interrupted and ignored the unsuspecting participants. Using mood and personality questionnaires, the data showed that participants who were particularly distressed after being snubbed by the researchers reported greater trust in other people if they sniffed oxytocin prior to the event" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems and Oxytocin Factor.

Vitamin D improves mood and blood pressure in women with diabetes - Science Daily, 6/25/13 - "The pilot study included 46 women who were an average age of 55 years, had diabetes an average of 8 years and insufficient blood levels of vitamin D (18 ng/ml). They took a weekly dose (50,000 International Units) of vitamin D ... After six months, their vitamin D blood levels reached sufficient levels (average 38 ng/ml) and their moods improved significantly. For example, in a 20-question depression symptom survey, scores decreased from 26.8 at the beginning of the study (indicating moderate depression) to 12.2 at six months (indicating no depression. (The depression scale ranges from 0 to 60, with higher numbers indicating more symptoms of depression.) ... Blood pressure also improved, with the upper number decreasing from 140.4 mm Hg to 132.5 mm Hg. And their weight dropped from an average of 226.1 pounds to 223.6 pounds" - See vitamin D at Amazon.com.

Note:  I modified my yogurt recipe.  I cut the incubation time down to 9 hours (then test it with a pH meter) by putting it in the microwave for 3 minutes 15 seconds which brings to temperature to about 100 degrees prior to adding the culture.

Prevention of Torsion-induced Testicular Injury by Rhodiola rosea - Urology. 2013 Jul;82(1):254.e1-254.e6 - "R. rosea extract was shown to have partially preventive effects on testicular injury induced by torsion in this rat model" - See Rhodiola rosea at Amazon.com.

Effect of green tea on glucose control and insulin sensitivity: a meta-analysis of 17 randomized controlled trials - Am J Clin Nutr. 2013 Jun 26 - "Seventeen trials comprising a total of 1133 subjects were included in the current meta-analysis. Green tea consumption significantly reduced the fasting glucose and hemoglobin A1c (Hb A1c) concentrations by -0.09 mmol/L (95% CI: -0.15, -0.03 mmol/L; P < 0.01) and -0.30% (95% CI: -0.37, -0.22%; P < 0.01), respectively. Further stratified analyses from high Jadad score studies showed that green tea significantly reduced fasting insulin concentrations (-1.16 μIU/mL; 95%CI: -1.91, -0.40 μIU/mL; P = 0.03)" - See green tea extract at Amazon.com.

High Concentrations of a Urinary Biomarker of Polyphenol Intake Are Associated with Decreased Mortality in Older Adults - J Nutr. 2013 Jun 26 - "Polyphenols might have a role in the prevention of several chronic diseases, but evaluating total dietary polyphenol (TDP) intake from self-reported questionnaires is inaccurate and unreliable. A promising alternative is to use total urinary polyphenol (TUP) concentration as a proxy measure of intake. The current study evaluated the relationship between TUPs and TDPs and all-cause mortality during a 12-y period among older adult participants ... In the multivariable Cox model, participants in the highest tertile of TUP at enrolment had a lower mortality rate than those in the lowest tertile [HR = 0.70 (95% CI: 0.49-0.99); P-trend = 0.045], whereas no significant associations were found between TDP and overall mortality. TUP is an independent risk factor for mortality among community-dwelling older adults, suggesting that high dietary intake of polyphenols may be associated with longevity" - See Jarrow Formulas, OPCs + 95 at Amazon.com.

Successful use of aromatase inhibitor letrozole in NOA with an elevated FSH level: a case report - Andrologia. 2013 Jun 26 - "We present the case of an infertile man with small testes and an elevated FSH level, which was diagnosed as NOA, hypospermatogenesis proven by testicular biopsy. After taking letrozole for 3 months, semen analyses by computer-aided sperm analysis present that this man had normal spermatogenesis"

Oxytocin blunts social vigilance in the rhesus macaque - Proc Natl Acad Sci U S A. 2013 Jun 24 - "Exogenous application of the neuromodulatory hormone oxytocin (OT) promotes prosocial behavior and can improve social function ... in the absence of competing task demands or goals, OT increased attention to faces and eyes, as in humans. By contrast, OT reduced species typical social vigilance for unfamiliar, dominant, and emotional faces in two additional tasks. OT eliminated the emergence of a typical state of vigilance when dominant face images were available during a social image choice task. Moreover, OT improved performance on a reward-guided saccade task, despite salient social distractors: OT reduced the interference of unfamiliar faces, particularly emotional ones, when these faces were task irrelevant. Together, these results demonstrate that OT suppresses vigilance toward potential social threats in the rhesus macaque" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems and Oxytocin Factor.

Neat Tech Stuff / "How To's":

  • Enerlites WOS-W Passive Infrared Single Pole Wall Switch Occupancy Sensor, White - After I listed those switches that work with LED's and CFL's last week I found this on.  It also has 4.5 stars.  I like it better because it's easier to see if you are in manual override plus it doesn't require programming, it has dials (click here and go to page 5).  However, unlike some of the others it requires the white, neutral wire. Remove the switch cover and check what you have before ordering it.  Click here for the programming instructions on the Lutron MS-OPS2-WH Maestro (it's a lot more difficult).  I've got five different brands/types of these switches including a ceiling mounted one and I've tried several different LED bulbs.  Walking from one end of my house to the other and having the lights follow me is really neat and saves on utilities.  I might give my reviews and picks for the best on both the switches and LED's next week.  When you think about it, I go in and out of my office about 30 times per day.  If I were to turn the lights on or off each time, that's 60 times per day just for the office.

News & Research:

  • New Optimism on Resveratrol - NYTimes.com, 3/11/13 - "Critics have suggested there were errors in the original experiments and that resveratrol did not in fact activate sirtuins directly. If so, resveratrol would lose much of its scientific interest because its link to the sirtuin would be unclear. But a new study led by David Sinclair of the Harvard Medical School, who in 2003 was a discoverer resveratrol’s role in activating sirtuins, found that resveratrol did indeed influence sirtuin directly, though in a more complicated way than previously thought ... This would explain why mice treated with resveratrol ran twice as far on a treadmill before collapsing from exhaustion as untreated mice" - See resveratrol products at Amazon.com.
  • Anti-aging drug breakthrough - Science Daily, 3/8/13 - "Drugs that combat aging may be available within five years ... The target enzyme, SIRT1, is switched on naturally by calorie restriction and exercise, but it can also be enhanced through activators. The most common naturally-occurring activator is resveratrol, which is found in small quantities in red wine, but synthetic activators with much stronger activity are already being developed ... While any drug would be strictly prescribed for certain conditions, Professor Sinclair suggests that one day, they could be taken orally as a preventative ... overweight mice given synthetic resveratrol were able to run twice as far as slim mice and they lived 15 per cent longer" - Note:  They've been saying that five year thing ever since I've been reading health articles.  In the mean time, see resveratrol products at Amazon.com.
  • Resveratrol shows promise to protect hearing, cognition - Science Daily, 2/20/13 - "Resveratrol is a very powerful chemical that seems to protect against the body's inflammatory process as it relates to aging, cognition and hearing loss ... Noise-induced hearing loss, too, is a growing medical issue among American troops, with more than 12 percent returning home from Iraq and Afghanistan with significant hearing loss ... acoustic over-stimulation causes a time-depended, up-regulation of COX-2 protein expression. And, resveratrol significantly reduces reactive oxygen species formation, inhibits COX-2 expression and reduces noise-induced hearing loss following noise exposure in rats"
  • Green tea and red wine extracts interrupt Alzheimer's disease pathway in cells - Science Daily, 2/5/13 - "They were able to interrupt this pathway using the purified extracts of EGCG from green tea and resveratrol from red wine ... Alzheimer's disease is characterised by a distinct build-up of amyloid protein in the brain, which clumps together to form toxic, sticky balls of varying shapes. These amyloid balls latch on to the surface of nerve cells in the brain by attaching to proteins on the cell surface called prions, causing the nerve cells to malfunction and eventually die ... The team formed amyloid balls in a test tube and added them to human and animal brain cells ... When we added the extracts from red wine and green tea, which recent research has shown to re-shape amyloid proteins, the amyloid balls no longer harmed the nerve cells" - See green tea extract at Amazon.com and resveratrol products at Amazon.com.
  • New evidence on how compound found in red wine can help prevent cancer - Science Daily, 12/4/12 - "Using laboratory models, they have found that a daily amount of resveratrol equivalent to two glasses of wine can halve the rate of bowel tumors ... The conference will include more than 65 lectures, presentations and posters by different researchers from all over the world"
  • Resveratrol Preserves Response to Morphine - Medscape, 11/20/12 - "Dr. Wong and colleagues induced morphine tolerance in rats and then tested whether resveratrol significantly enhanced the effects of morphine ... They found that the pain-relieving response to morphine was only about 20% of normal in the morphine-tolerant rats, whereas in similar rats receiving resveratrol, morphine responses were restored to about 60% of normal"
  • Compound in grapes, red wine could be key to fighting prostate cancer - Science Daily, 11/9/12 - "Prostate tumor cells contain very low levels of two proteins, perforin and granzyme B, which can function together to kill cells. However, both proteins need to be highly "expressed" to kill tumor cells. In his study, when Nicholl introduced resveratrol into the prostate tumor cells, the activity of the two proteins increased greatly. Following radiation treatment, Nicholl found that up to 97 percent of the tumor cells died, which is a much higher percentage than treatment with radiation alone"
  • Resveratrol may preserve pain-relieving effects of morphine - Science Daily, 9/25/12 - "If the findings are confirmed in humans, resveratrol might become a useful addition to clinical pain management approaches -- especially in patients with chronic, severe pain who have become tolerant to the effects of morphine ... In morphine-tolerant rats, the pain-relieving response to morphine was about 20 percent of normal. In rats receiving resveratrol, morphine responses were restored to about 60 percent of normal ... resveratrol appeared to work in two ways. It reversed the increase in expression of a type of neurotransmitter (N-methyl D-aspartate, or NMDA) receptors associated with morphine tolerance. Resveratrol also blocked the increase of inflammation-promoting substances, called cytokines, in rats with morphine tolerance"
  • Preventing noise-induced hearing loss, tinnitus in soldiers - Science Daily, 9/6/12 - "Antioxidants, dietary supplements and high-tech brain imaging are among some of the novel strategies that may help detect, treat and even prevent noise-induced hearing loss and tinnitus among American troops ... Noise-induced hearing loss doesn't just impact a person's ability to hear; it can cause balance issues, make it difficult to sleep and communicate, and even raise the risk for heart disease by increasing a person's blood pressure, lipids and blood sugar ... Dr. Seidman will discuss the use of nutraceuticals, such as acetyl-l-carnitine, alpha lipoic acid and resveratrol ... a nutraceutical with a resveratrol-based component may possibly hold the potential to not only prevent, but reverse hearing loss in certain circumstances for soldiers. This research is based on animal models, but will soon be tested with humans"
  • Resveratrol may be natural exercise performance enhancer - Science Daily, 6/19/12 - "high doses of the natural compound resveratrol improved physical performance, heart function and muscle strength in lab models ... resveratrol showed results similar to what you would see from extensive endurance exercise training ... I think resveratrol could help patient populations who want to exercise but are physically incapable. Resveratrol could mimic exercise for them or improve the benefits of the modest amount of exercise that they can do"
  • Study resolves controversy on life-extending red wine ingredient, restores hope for anti-aging pill - Science Daily, 5/1/12 - "The new findings show for the first time that the metabolic benefits of the red wine ingredient known as resveratrol evaporate in mice that lack the famed longevity gene SIRT1 ... They show that resveratrol targets SIRT1 directly at moderate doses and hits other targets at higher ones. Importantly, SIRT1 is required for resveratrol's benefits irrespective of dose"
  • Red wine antioxidant could give metabolism a boost - USATODAY.com, 11/1/11 - "For the study, Schrauwen's team gave resveratrol to 11 obese, but otherwise healthy men. The men took 150 milligrams of the supplement a day for 30 days. To get that much resveratrol from wine would mean drinking over two gallons of wine a day ... resveratrol acted much like a low-calorie diet in terms of reducing energy expenditure and improving metabolism and overall health ... Changes included a lower metabolic rate, reduced fat in the liver, lower blood pressure and lower blood sugar. The men also had changes in the way their muscles burned fat ... In obesity, it's not clear whether burning fewer calories is a good or a bad thing ... It suggests, however, that cells were functioning more efficiently, as they do on a calorie-restricted diet" - [ABC News]
  • Resveratrol may boost oral health: Cell study - Nutra USA, 10/26/11 - "If additional studies support the Hong Kong findings then oral health may also be added to the list of potential benefits of resveratrol ... Results showed that levels of both A. actinomycetemcomitans and P. gingivalis were significantly decreased after 1 hour and that no viable bacterial cells were observed after 24 hours ... Resveratrol had no effect on the other non-periodontitis promoting oral microorganisms, said the researchers ... the researchers note that periodontal disease involves an inflammatory process, and that a recent study has suggested that resveratrol may block this process by preventing the binding of a pro-inflammatory compound called nuclear factor kappaB" - [Abstract]
  • Red wine ingredient resveratrol stops breast cancer growth, study suggests - Science Daily, 9/29/11 - "resveratrol, the "healthy" ingredient in red wine, stops breast cancer cells from growing by blocking the growth effects of estrogen ... resveratrol is able to counteract the malignant progression since it inhibits the proliferation of hormone resistant breast cancer cells. This has important implications for the treatment of women with breast cancer whose tumors eventually develop resistance to hormonal therapy ... Resveratrol is a potential pharmacological tool to be exploited when breast cancer become resistant to the hormonal therapy"
  • Powerful antioxidant resveratrol prevents metabolic syndrome in lab tests, study finds - Science Daily, 9/2/11 - "administering resveratrol to the young offspring of lab rats after weaning actually prevented the development of a metabolic syndrome, which is characterized by glucose intolerance, insulin resistance and higher deposits of abdominal fat"
  • Resveratrol bioavailability boosted by piperine: Study - Nutra USA, 8/16/11 - "Using mice, Prof Ahmad and his co-workers analyzed the level of exposure and maximum blood levels of resveratrol achieved by combining 100 milligrams of resveratrol per kilogram of animal with 10 mg/kg of piperine ... Compared to resveratrol alone, combination with piperine was found to increase the degree of exposure to 229 percent, and the maximum levels in the blood by a whopping 1,544 percent" - [Abstract] - See piperine at Amazon.com.
  • Curry spice could offer treatment hope for tendinitis - Science Daily, 8/9/11 - "Tendons, the tough cords of fibrous connective tissue that join muscles to bones, are essential for movement because they transfer the force of muscle contraction to bones. However, they are prone to injury, particularly in athletes who may overstretch themselves and overuse their joints. Tendinitis (or tendonitis) is a form of tendon inflammation, which causes pain and tenderness near to joints and is particularly common in shoulders, elbows, knees, hips, heels or wrists. Other examples of common tendon disease include tennis and golfer's elbow and Achilles tendinitis ... introducing curcumin in the culture system inhibits NF-kB and prevents it from switching on and promoting further inflammation ... The results follow on from another study by the Nottingham-Munich collaboration, published in the Journal of Biological Chemistry earlier this year, demonstrating that a compound found in red wine could have therapeutic potential for osteoporosis related bone loss in elderly patients, post-menopausal women and patients with rheumatoid arthritis ... The research found that resveratrol, a naturally occurring phytoestrogen found in the skin of red grapes, vines and various other fruits and nuts, inhibits inflammation in bone cells. Its effects extended to inhibiting the formation of osteoclasts, giant congregations of blood-derived cells responsible for bone degeneration, especially in osteoporosis in later life. Resveratrol prevented NF-kB from switching on to trigger inflammation"
  • Red wine: Exercise in a bottle? - Science Daily, 6/30/11 - "a new research study published in the FASEB Journal, suggests that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people ... Scientists studied rats that underwent simulated weightlessness by hindlimb tail suspension and were given a daily oral load of resveratrol. The control group showed a decrease in soleus muscle mass and strength, the development of insulin resistance, and a loss of bone mineral density and resistance to breakage. The group receiving resveratrol showed none of these complications ... This study also suggests that resveratrol may be able to prevent the deleterious consequences of sedentary behaviors in humans"
  • Resveratrol studies confirms potential health boost - Science Daily, 6/21/11 - "A comprehensive review of human clinical research on resveratrol has found it has "anti-aging, anti-carcinogenic, anti-inflammatory and antioxidant properties," ...this polyphenol -- an antibiotic substance produced by plants as a defense against microorganisms -- prevents the growth of some cancers in mice, inhibits enzymes that cause inflammation, shrinks tumors and increases blood flow, thus reducing cardiovascular diseases. In many cases, it also extends the life of obese animals. Some evidence also shows that resveratrol could one day be used to help regulate insulin sensitivity in diabetic patients"
  • Study unlocks resveratrol’s fat fighting potential - Nutra USA, 5/11/11 - "It is important to point out that the effective dose in our experimental design, as well as those used by other authors, is far greater than the amount usually ingested by humans (100-930 micrograms per day), meaning that the positive effects of this molecule on body fat would only be achieved by the intake of resveratrol pills or functional foods enriched with this molecule ... resveratrol could activate a gene called sirtuin1 (Sirt1 – the yeast equivalent was Sir2), which is also activated during calorie restriction in various species, including monkeys ... divided 16 rats into two equal groups ... After six weeks of study, the researchers found that both groups had similar body weight, but that the resveratrol fed animals has significantly lower fat tissue levels"
  • Resveratrol may be useful tool for reducing body fat - Science Daily, 3/4/11 - "This thesis shows, on the one hand, the results obtained after treatment with CLA in hamsters subjected to energy restriction and, on the other, the effect of resveratrol on accumulated fat and lipolytic activity in cell cultures of adipocytes of murinae and humans. The results obtained show that CLA does not foment weight or body fat loss, induced by an energy restriction diet. Neither does it induce greater lipolysis, nor improvement in serum parameters, in glucose homeostasis or insulin function to any greater extent than with the slimming diet itself. On the contrary, resveratrol reduces the accumulation of triglycerides, in part by activation of lipolysis, in both the adipocytes of mice and of humans ... For all these reasons, it can be concluded that, while CLA may not be a molecule useful in treating obesity, when resveratrol is included in hypocaloric diet, it could well be a useful tool for reducing body fat" - See resveratrol products at Amazon.com and conjugated linoleic acid at Amazon.com.
  • Young rats given polyphenols show less endothelial function deterioration with aging - Science Daily, 1/31/11 - "The endothelium is the inner lining of our blood vessels and normal functions of endothelial cells include enabling coagulation, platelet adhesion and immune function. Endothelial dysfunction is associated with reduced anticoagulant properties and the inability of arteries and arterioles to dilate fully ... The gradual decrease in endothelial function over time is a key factor in the development of diseases associated with ageing, especially cardiovascular disease (CVD).  Many epidemiologic studies suggest protection against CVD from moderate intake of alcoholic beverages, especially those rich in antioxidants, such as red wine, which is high in polyphenols (RWPs) ... RWPs and apocynin improved the endothelial dysfunction, normalized oxidative stress and the expression of the different proteins. RWPs also improved ageing-related decline in physical exercise. Thus, intake of RWPs protects against ageing-induced endothelial dysfunction and decline in physical performance ... RWPs intake had also a physiological beneficial effect since it improved the physical exercise capacity of old rats"
  • 'Longevity' protein SIRT1 may ward off precursor to prostate cancer - Science Daily, 1/13/11 - "prostatic intraepithelial neoplasia (PIN) ... deletion of the Sirt1 gene in mice resulted in PIN lesion formation associated with reduced autophagy, which is the necessary degradation of a cell's own components and most likely essential for tumor suppression ... it tells you that this 'longevity' gene is normally blocking prostate cancer" - Note: Resveratrol increases Sirt1:
    • Sirtuin1 may boost memory and learning ability; Discovery could lead to new drugs to fight Alzheimer's, other neurological diseases - Science Daily, 7/11/10 - "Resveratrol, found in wine, has been touted as a life-span enhancer because it activates a group of enzymes known as sirtuins, which have gained fame in recent years for their ability to slow the aging process. Now MIT researchers report that Sirtuin1 -- a protein that in humans is encoded by the SIRT1 gene -- also promotes memory and brain flexibility ... We have now found that SIRT1 activity also promotes plasticity and memory"
    • Slowing Aging: Anti-aging Pathway Enhances Cell Stress Response - Science Daily, 2/19/09 - "The researchers discovered a new molecular relationship critical to keeping cells healthy across a long span of time: a protein called SIRT1, important for caloric restriction and lifespan and activated by resveratrol, regulates heat shock factor 1 (HSF1), keeping it active. HSF1 in turn senses the presence of damaged proteins in the cell and elevates the expression of molecular chaperones to keep a cell's proteins in a folded, functional state. Regulation of this pathway has a direct beneficial effect to cells ... decrease in SIRT1 may help explain why protein misfolding diseases, such as Alzheimer's, Parkinson's, Huntington's and adult-onset diabetes, are diseases of aging"
    • Wine Compound Spurs Diabetes Research - WebMD, 11/29/07 - "In October, Chinese researchers reported that resveratrol curbs insulin resistance in mice. Insulin is a hormone that controls blood sugar. Insulin resistance can lead to type 2 diabetes ... Like resveratrol, the lab-made chemicals activate a gene called SIRT1, making the diabetic mice more sensitive to insulin ... the newly developed chemicals are 1,000 times more potent than resveratrol"
  • Resveratrol’s health benefits linked to fat hormone control - Nutra USA, 1/11/11 - "adiponectin has a wide range of beneficial effects on obesity-related medical complications, and noted that both adiponectin and resveratrol display anti-obesity, anti-insulin resistance and anti-aging properties" - [Abstract]
  • Resveratrol shows metabolic benefits for obese: Study - Nutra USA, 10/11/10 - "When human fat cells were exposed to IL-1B, the researchers noted increases in the secretion of pro-inflammatory compounds, including IL6, IL8, MCP-1. However, when the cells were simultaneously exposed to resveratrol, a 16 to 36 percent reduction in the expression of these cytokines was observed" - [Abstract]
  • Resveratrol May Slow Aging in Humans - Medscape, 8/6/10 - "the popular plant extract has been shown to prolong life and reduce the rate of aging in roundworms, fruit flies, and yeast, apparently because resveratrol affects a gene associated with longevity ... resveratrol suppressed the generation of “free radicals” -- unstable molecules known to cause oxidative stress and release pro-inflammatory substances into the blood, resulting in damage to the blood vessel lining ... resveratrol also showed suppression of the inflammatory protein tumor necrosis factor, or TNF, and other compounds that increase blood vessel inflammation and interfere with insulin action, causing insulin resistance and the risk of developing diabetes"
  • Resveratrol’s anti-inflammatory power gets human data boost - Nutra USA, 8/3/10 - "The results demonstrated in the research are the first time that such findings have been seen in humans, but are consistent with potential antiatherogenic and antiaging effects of resvertatrol. Concluding that PCE “has a comprehensive suppressive effect on oxidative and inflammatory stress.”" -[Abstract]
  • Plant compound resveratrol shown to suppresses inflammation, free radicals in humans - Science Daily, 7/29/10 - "Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans ... resveratrol has been shown to prolong life and to reduce the rate of aging in yeast, roundworms and fruit flies, actions thought to be affected by increased expression of a particular gene associated with longevity ... The compound also is thought to play a role in insulin resistance as well, a condition related to oxidative stress, which has a significant detrimental effect on overall health ... resveratrol suppressed the generation of free radicals, or reactive oxygen species, unstable molecules known to cause oxidative stress and release proinflammatory factors into the blood stream, resulting in damage to the blood vessel lining ...

Resveratrol is an anti-fungal compound found in the skins of red grapes and other fruits and nuts. We examined the ability of resveratrol to inhibit lipopolysaccharide (LPS)-induced production of inflammatory molecules from primary mouse astrocytes. Resveratrol inhibited LPS-induced production of nitric oxide (NO); the cytokines tumor necrosis factor-alpha (TNF-α), interleukin 1-beta (IL-1β), and IL-6; and the chemokine monocyte chemotactic protein-1 (MCP-1), which play critical roles in innate immunity, by astrocytes. Resveratrol also suppressed astrocyte production of IL-12p40 and IL-23, which are known to alter the phenotype of T cells involved in adaptive immunity. Finally resveratrol inhibited astrocyte production of C-reactive protein (CRP), which plays a role in a variety of chronic inflammatory disorders.

Thus, resveratrol might represent a potential benefit for the treatment of inflammation-related neurological disorders"
  • One-Year Consumption of a Grape Nutraceutical Containing Resveratrol Improves the Inflammatory and Fibrinolytic Status of Patients in Primary Prevention of Cardiovascular Disease - Am J Cardiol. 2012 Apr 19 - "In contrast to placebo and conventional grape supplement, the resveratrol-rich grape supplement significantly decreased high-sensitivity C-reactive protein (-26%, p = 0.03), tumor necrosis factor-α (-19.8%, p = 0.01), plasminogen activator inhibitor type 1 (-16.8%, p = 0.03), and interleukin-6/interleukin-10 ratio (-24%, p = 0.04) and increased anti-inflammatory interleukin-10 (19.8%, p = 0.00). Adiponectin (6.5%, p = 0.07) and soluble intercellular adhesion molecule-1 (-5.7%, p = 0.06) tended to increase and decrease, respectively. No adverse effects were observed in any patient. In conclusion, 1-year consumption of a resveratrol-rich grape supplement improved the inflammatory and fibrinolytic status in patients who were on statins for primary prevention of CVD and at high CVD risk (i.e., with diabetes or hypercholesterolemia plus ≥1 other CV risk factor). Our results show for the first time that a dietary intervention with grape resveratrol could complement the gold standard therapy in the primary prevention of CVD" - See resveratrol products at Amazon.com.
  • Improvements in Skeletal Muscle Strength and Cardiac Function Induced by Resveratrol Contribute to Enhanced Exercise Performance in Rats - J Physiol. 2012 Apr 2 - "Exercise training (ET) improves endurance capacity by increasing both skeletal muscle mitochondrial number and function, as well as contributing to favourable cardiac remodelling. Interestingly, some of the benefits of regular exercise can also be mimicked by the naturally occurring polyphenol, resveratrol (RESV). However, it is not known whether RESV enhances physiologic adaptations to ET. To investigate this, male Wistar rats were randomly assigned to a control chow diet or a chow diet that contained RESV (4g/kg of diet) and subsequently subjected to a program of progressive treadmill running for 12-weeks. ET-induced improvements in exercise tolerance were enhanced by 21% (p<0.001) by the addition of RESV to the diet ... Overall, our findings provide evidence that the capacity for fatty acid oxidation is augmented by the addition of RESV to the diet during ET, and that this contributes to the improved physical performance of rats following ET"

  • Resveratrol prevents Streptozotocin-induced diabetes by inhibiting the apoptosis of pancreatic β-cell and the cleavage of poly (ADP-ribose) polymerase - Endocr J. 2011 Nov 8 - "Resveratrol (3,5,4'-trihydroxystilbene; RSV) is one kind of polyphenolic phytoalexin that has many effects on metabolic diseases. This study aimed to evaluate the protective effect of RSV pretreatment on β-cell. Male Sprague Dawley rats weighing 200-230 g were divided into 4 groups: (1) RSV; (2) streptozotocin (STZ, 70 mg/kg, intraperitoneally); (3) STZ after 7 days pretreatment with RSV; and (4) STZ pretreated with nicotinamide. Fasting glucose concentration was measured and an intraperitoneal glucose tolerance test was performed 72 h after STZ injection to determine the diabetic condition. The pancreas was removed 3, 6, 36, and 48 h after STZ injection. STZ induced diabetes in all rats not given RSV pretreatment, whereas none of the RSV-pretreated rats developed diabetes. Pretreatment with RSV inhibited apoptosis and reduced the activation of caspase-3 and poly(ADP-ribose) polymerase (PARP). However, expression of the total length PARP was not affected by pretreatment. Our findings suggest that RSV protects β-cells from STZ simultaneously with inhibiting the activation of PARP"
  • Low-Dose Dietary Resveratrol Has Differential Effects on Colorectal Tumorigenesis in Adiponectin Knockout and Wild-Type Mice - Nutr Cancer. 2011 Sep 29 - "Obesity is associated with a decrease in the antiinflammatory hormone, adiponectin, and increases in the circulating concentrations of multiple proinflammatory cytokines. These changes contribute to colon tumorigenesis. Resveratrol increases adiponectin production in adipocytes and attenuates the development of colon cancer. Thus, we hypothesized that adiponectin is an integral component of the mechanism by which resveratrol antagonizes colorectal tumorigenesis. To investigate this, we induced tumorigenesis in adiponectin knockout (KO) and wild-type (Wt) C57BL/6 mice through combined azoxymethane and dextran sodium sulfate treatment during which mice were fed a high-fat, lard-based diet, or the same diet containing 20 mg/kg resveratrol. After 14 wk on diet, Wt mice gained more weight and, on a percentage basis, had higher fat mass and lower lean mass than KO mice. Resveratrol tended to attenuate this response in male Wt mice. Resveratrol also tended to reduce aberrant crypt foci development and decrease circulating interleukin 6 and insulin concentrations in male but not female Wt mice. Taken together, resveratrol improved overall health of obese Wt but not KO mice as hypothesized with a differential sex response"
  • Repeated and long-term treatment with physiological concentrations of resveratrol promotes NO production in vascular endothelial cells - Br J Nutr. 2011 Jul 27:1-7 - "Repeated treatment with resveratrol for 5 d resulted in an increase in endothelial NO synthase (eNOS) protein content and NO production in human umbilical vein endothelial cell (HUVEC) in a concentration-dependent manner. A significant increase in functional eNOS protein content was observed with resveratrol, even at 50 nm. In contrast, eNOS phosphorylation was not stimulated and inducible NO synthase (iNOS) was not detected after resveratrol treatment. Both eNOS protein and mRNA expression were promoted by 50 nm-resveratrol in a time-dependent manner. Increased eNOS mRNA expression in response to resveratrol was not decreased by an oestrogen receptor (ER) antagonist ICI182780, a PPARα inhibitor MK886 or a sirtuin inhibitor Salermide. However, a combination of ICI182780 and MK886 significantly inhibited resveratrol-induced eNOS mRNA expression. Salermide had no effect even in the presence of ICI182780 or MK886. These results demonstrate that resveratrol within the physiological range increases eNOS mRNA and protein expression through ER and PPARα activation, thereby promoting NO production in endothelial cells. eNOS induction might result from the accumulative effect of nanomolar concentrations of resveratrol. The present study results can account in part for the observation that cardiovascular benefits of red wine are experienced with routine consumption, but not with acute consumption"
  • Resveratrol attenuates steatosis in obese Zucker rats by decreasing fatty acid availability and reducing oxidative stress - Br J Nutr. 2011 Jun 28:1-9 - "Resveratrol reduced liver weight and TAG content. It did not modify the activity of lipogenic enzymes but it did increase CPT-Ia and ACO activities. NEFA and ALP were reduced in both resveratrol-treated groups. AST/GOT was reduced only by the lowest dose. ALT/GPT, TAG and adiponectin remained unchanged. Resveratrol reduced liver oxidative stress. This study demonstrates that resveratrol can protect the liver from NAFLD by reducing fatty acid availability. Moreover, resveratrol also protects liver from oxidative stress"

  • Oral Resveratrol Therapy Inhibits Cancer-Induced Skeletal Muscle and Cardiac Atrophy In Vivo - Nutr Cancer. 2011 Jun 8:1 - "The mechanism by which cancer mediates muscle atrophy has been delineated in the past 3 decades and includes a prominent role of tumor-derived cytokines, such as IL-6, TNFα, and IL-1. These cytokines interact with their cognate receptors on muscle to activate the downstream transcription factor NF-κB and induce sarcomere proteolysis. Experimentally, inhibiting NF-κB signaling largely prevents cancer-induced muscle wasting, indicating its prominent role in muscle atrophy. Resveratrol, a natural phytoalexin found in the skin of grapes, has recently been shown to inhibit NF-κB in cancer cells, which led us to hypothesize that it might have a protective role in cancer cachexia. Therefore, we investigated whether daily oral resveratrol could protect against skeletal muscle loss and cardiac atrophy in an established mouse model. We demonstrate resveratrol inhibits skeletal muscle and cardiac atrophy induced by C26 adenocarcinoma tumors through its inhibition of NF-κB (p65) activity in skeletal muscle and heart. These studies demonstrate for the first time the utility of oral resveratrol therapy to provide clinical benefit in cancer-induced atrophy through the inhibition of NF-κB in muscle. These findings may have application in the treatment of diseases with parallel pathophysiologies such as muscular dystrophy and heart failure"

Interestingly, there were also significant increases in expression levels of LASS genes and decreases in expression levels of GCS and SK-1 in K562 cells in response to resveratrol. Our data, in total, showed for the first time that resveratrol might kill CML cells through increasing intracellular generation and accumulation of apoptotic ceramides"
  • A Dietary Mixture Containing Fish Oil, Resveratrol, Lycopene, Catechins, and Vitamins E and C Reduces Atherosclerosis in Transgenic Mice - J Nutr. 2011 Mar 16 - "Chronic inflammation and proatherogenic lipids are important risk factors of cardiovascular disease (CVD). Specific dietary constituents such as polyphenols and fish oils may improve cardiovascular risk factors and may have a beneficial effect on disease outcomes ... AIDM was evaluated in an inflammation model, male human C-reactive protein (CRP) transgenic mice, and an atherosclerosis model, female ApoE*3Leiden transgenic mice. Two groups of male human-CRP transgenic mice were fed AIDM [0.567% (wt:wt) powder and 0.933% (wt:wt oil)] or placebo for 6 wk. The effects of AIDM on basal and IL-1β-stimulated CRP expression were investigated. AIDM reduced cytokine-induced human CRP and fibrinogen expression in human-CRP transgenic mice. In the atherosclerosis study, 2 groups of female ApoE*3Leiden transgenic mice were fed an atherogenic diet supplemented with AIDM [0.567% (wt:wt) powder and 0.933% (wt:wt oil)] or placebo for 16 wk. AIDM strongly reduced plasma cholesterol, TG, and serum amyloid A concentrations compared with placebo. Importantly, long-term treatment of ApoE*3Leiden mice with AIDM markedly reduced the development of atherosclerosis by 96% compared with placebo. The effect on atherosclerosis was paralleled by a reduced expression of the vascular inflammation markers and adhesion molecules inter-cellular adhesion molecule-1 and E-selectin. Dietary supplementation of AIDM improves lipid and inflammatory risk factors of CVD and strongly reduces atherosclerotic lesion development in female transgenic mice" - See resveratrol products at Amazon.com, Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com, Jarrow Formulas, CarotenALL at Amazon.com, green tea extract at Amazon.com and Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.
  • Resveratrol improves insulin sensitivity, reduces oxidative stress and activates the Akt pathway in type 2 diabetic patients - Br J Nutr. 2011 Mar 9:1-7 - "After an initial general examination (including blood chemistry), nineteen patients enrolled in the 4-week-long double-blind study were randomly assigned into two groups: a resveratrol group receiving oral 2 × 5 mg resveratrol and a control group receiving placebo. Before and after the second and fourth weeks of the trial, insulin resistance/sensitivity, creatinine-normalised ortho-tyrosine level in urine samples (as a measure of oxidative stress), incretin levels and phosphorylated protein kinase B (pAkt):protein kinase B (Akt) ratio in platelets were assessed and statistically analysed. After the fourth week, resveratrol significantly decreased insulin resistance (homeostasis model of assessment for insulin resistance) and urinary ortho-tyrosine excretion, while it increased the pAkt:Akt ratio in platelets. On the other hand, it had no effect on parameters that relate to β-cell function (i.e. homeostasis model of assessment of β-cell function). The present study shows for the first time that resveratrol improves insulin sensitivity in humans, which might be due to a resveratrol-induced decrease in oxidative stress that leads to a more efficient insulin signalling via the Akt pathway"
  • Resveratrol improves hippocampal atrophy in chronic fatigue mice by enhancing neurogenesis and inhibiting apoptosis of granular cells - Biol Pharm Bull. 2011;34(3):354-9 - "Neuroimaging evidence showed structural and/or functional abnormalities existing in the central nervous system, especially the hippocampus, in chronic fatigue syndrome (CFS) patients. However, its pathophysiologic mechanisms are unclear in part due to the lack of an applicable animal model. We established a chronic fatigue murine model by six repeated injections of Brucella abortus antigen to mice, which was manifested as reduced daily running activity and hippocampal atrophy. Thereafter, resveratrol, a polyphenolic activator of sirtuin 1, was used for treatment in this model. Daily running activity was increased by more than 20%, and the hippocampus was enlarged after 4-week resveratrol therapy. Furthermore, resveratrol inhibited neuronal apoptosis and expression of hippocampal acetylated p53 in the fatigue mice. Resveratrol also improved neurogenesis and expression of brain-derived neurotrophic factor mRNA in the hippocamous. We concluded that repeated injection of B. abortus antigen could induce hypoactivity and hippocampal atrophy in mice. Resveratrol may be effective for improving fatigue symptoms and enlarging the atrophic hippocampus by repressing apoptosis and promoting neurogenesis"
  • Pterostilbene Is More Potent than Resveratrol in Preventing Azoxymethane (AOM)-Induced Colon Tumorigenesis via Activation of the NF-E2-Related Factor 2 (Nrf2)-Mediated Antioxidant Signaling Pathway - J Agric Food Chem. 2011 Feb 28 - "Inflammatory bowel diseases have been a risk factor of colorectal cancer (CRC). The reactive oxygen species (ROS) generated by inflammatory cells create oxidative stress and contribute to neoplastic transformation, proliferation, and even metastasis. Previously, resveratrol (RS) and pterostilbene (PS) had been reported to prevent chemical-induced colon carcinogenesis by anti-inflammatory and pro-apoptotic properties ... Administrations of PS can be more effective than RS in reducing AOM-induced formation of aberrant crypt foci (ACF), lymphoid nodules (LNs), and tumors. We also find that PS is functioning more effectively than RS to reduce nuclear factor-κB (NF-κB) activation by inhibiting the phosphorylation of protein kinase C-β2 (PKC-β2) and decreasing downstream target gene expression, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and aldose reductase (AR) in mouse colon stimulated by AOM. Moreover, administration of RS and PS for 6 weeks significantly enhanced expression of antioxidant enzymes, such as heme oxygenase-1 (HO-1) and glutathione reductase (GR), via activation of NF-E2-related factor 2 (Nrf2) signaling. When the above findings are taken together, they suggest that both stilbenes block cellular inflammation and oxidative stress through induction of HO-1 and GR, thereby preventing AOM-induced colon carcinogenesis. In comparison, PS was a more potent chemopreventive agent than RS for the prevention of colon cancer. This is also the first study to demonstrate that PS is a Nrf2 inducer and AR inhibitor in the AOM-treated colon carcinogenesis model" - See pterostilbene at iHerb.
  • A Resveratrol and Polyphenol Preparation Suppresses Oxidative and Inflammatory Stress Response to a High-Fat, High-Carbohydrate Meal - J Clin Endocrinol Metab. 2011 Feb 2 - "High-fat, high-carbohydrate (HFHC) meals are known to induce oxidative and inflammatory stress, an increase in plasma endotoxin concentrations, and an increase in the expression of suppressor of cytokine signaling-3 (SOCS-3) ...

  • RESVERATROL-MEDIATED SIRT-1 INTERACTIONS WITH P300 MODULATE RANKL-ACTIVATION OF NF-kappaB SIGNALING AND INHIBIT OSTEOCLASTOGENESIS IN BONE-DERIVED CELLS - J Biol Chem. 2011 Jan 14 - "Resveratrol is a polyphenolic phyto-estrogen that has been shown to exhibit potent anti-oxidant, anti-inflammatory and anti-catabolic properties. Increased osteoclastic and decreased osteoblastic activity result in bone resorption and loss of bone mass. These changes have been implicated in pathological processes in rheumatoid arthritis (RA) and osteoporosis. Receptor activator of NF-kappaB ligand (RANKL), a member of the TNF superfamily, is a major mediator of bone loss. In this study we investigated the effects of resveratrol on RANKL during bone morphogenesis in high-density bone cultures in vitro ... Treatment with RANKL induced formation of TRAP positive multinucleated cells that exhibited morphological features of osteoclasts. RANKL induced NF-kappaB activation, whereas pre-treatment with resveratrol completely inhibited this activation, suppressed the activation of IkappaBα kinase, IkappaBα phosphorylation and degradation ... Resveratrol inhibited RANKL-induced acetylation and nuclear translocation of NF-kappaB in a time and concentration dependent manner. In addition, activation of Sirt-1 (a histone deacetylase) by resveratrol induced Sirt-1-p300 association in bone-derived and pre-osteoblastic cells, leading to deacetylation of RANKL-induced NF-kappaB, inhibition of NF-kappaB transcriptional activation and osteoclastogenesis. Co-treatment with resveratrol activated the bone transcription factor Cbfa-1, Sirt-1 and induced the formation of Sirt-1/Cbfa-1-complexes. Overall, these results demonstrate that resveratrol-activated Sirt-1 plays pivotal roles in regulating the balance between osteoclastic versus osteoblastic activity result in bone formation in vitro thereby highlighting its therapeutic potential for treating osteoporosis and RA-related bone loss"

  • Resveratrol enhances the anti-tumor activity of the mTOR inhibitor rapamycin in multiple breast cancer cell lines mainly by suppressing rapamycin-induced AKT signaling - Cancer Lett. 2010 Dec 16 - "The anti-tumor activity of rapamycin is compromised by the feedback-loop-relevant hyperactive PI3K and ERK-MAPK pathway signaling. In breast cancer cells treated with rapamycin, we observed a moderate increase of AKT phosphorylation (P-AKT) in a rapamycin resistant cell line, MDA-MB-231, as well as a slight increase of P-AKT in a rapamycin sensitive cell line, MCF-7. We found that resveratrol, a natural phytoalexin, suppressed the phosphorylation and activation of the PI3K/AKT pathway in all the three breast cancer cell lines that we tested. It also had a weak inhibitory effect on the activation of the mTOR/p70S6K pathway in two cell lines expressing wildtype PTEN, MCF-7 and MDA-MB-231. The combined use of resveratrol and rapamycin resulted in modest additive inhibitory effects on the growth of breast cancer cells, mainly through suppressing rapamycin-induced AKT activation"

  • Resveratrol Protects against Oxidized LDL-Induced Breakage of the Blood-Brain Barrier by Lessening Disruption of Tight Junctions and Apoptotic Insults to Mouse Cerebrovascular Endothelial Cells - J Nutr. 2010 Oct 27 - "Cerebrovascular endothelial cells (CEC) ... Exposure of mouse CEC to 200 μmol/L oxLDL for 1 h did not cause cell death but significantly altered the permeability and transendothelial electrical resistance of the cell monolayer. However, resveratrol completely normalized such injury. As for the mechanisms, resveratrol completely protected oxLDL-induced disruption of F-actin and microtubule cytoskeletons as well as occludin and zona occludens-1 (ZO-1) tight junctions. The oxLDL-induced decreases in the mitochondrial membrane potential and intracellular ATP levels were normalized by resveratrol. Exposure of mouse CEC to 200 μmol/L oxLDL for 24 h elevated oxidative stress and simultaneously induced cell apoptosis. However, resveratrol partially protected against oxLDL-induced CEC apoptosis. The oxLDL-induced alterations in levels of Bcl-2, Bax, and cytochrome c were completely normalized by resveratrol. Consequently, resveratrol partially decreased oxLDL-induced activation of caspases-9 and -3. Therefore, in this study, we show that resveratrol can protect against oxLDL-induced damage of the BBB through protecting disruption of the tight junction structure and apoptotic insults to CEC"

  • Dietary polyphenols: Focus on resveratrol, a promising agent in the prevention of cardiovascular diseases and control of glucose homeostasis - Nutr Metab Cardiovasc Dis. 2010 Oct;20(8):618-25 - "Plants continuously produce an extraordinary variety of biologically active low-molecular-mass compounds. Among them, resveratrol (3,5,4'-trihydroxystilbene) is endowed with significant positive activities by protecting against cardiovascular diseases and preventing the development and progression of atherosclerosis. Furthermore, the molecule significantly ameliorates glucose homeostasis in obese mice. These beneficial effects have driven considerable interest towards resveratrol molecular activities, and intensive efforts for the identification of the stilbene targets have been made. The molecule shows a pleiotropic mode of action. Particularly, its cellular targets are crucial for cell proliferation and differentiation, apoptosis, antioxidant defence and mitochondrial energy production. The complexity of resveratrol activities might account for its effectiveness in ameliorating multifactorial processes, including the onset and/or progression of several degenerative diseases such as myocardial infarction, atherosclerosis and type 2 diabetes"

  • Dietary supplementation of resveratrol attenuates chronic colonic inflammation in mice - Eur J Pharmacol. 2010 May 10;633(1-3):78-84 - "Our results demonstrated that resveratrol group significantly attenuated the clinical signs such as loss of body weight, diarrhea and rectal bleeding improving results from disease activity index and inflammatory score. Moreover, the totality of resveratrol-fed animals survived and finished the treatment while animals fed with standard diet showed a mortality of 40%. Three weeks after DSS removal, the polyphenol caused substantial reductions of the rise of pro-inflammatory cytokines, TNF-alpha and IL-1beta and an increase of the anti-inflammatory cytokine IL-10. Also resveratrol reduced prostaglandin E synthase-1 (PGES-1), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) proteins expression, via downregulation of p38, a mitogen-activated protein kinases (MAPK) signal pathway. We conclude that resveratrol diet represents a novel approach to the treatment of chronic intestinal inflammation"

  • Pro-ulcer effects of resveratrol in mice with indomethacin-induced gastric ulcers are reversed by l-arginine - Br J Pharmacol. 2010 Jan 8 - "Although resveratrol is currently being evaluated in pre-clinical studies as a potential cancer chemopreventive agent and cardiovascular stress-releasing compound, treatment with resveratrol severely delays healing of pre-existing gastric ulcers. Resveratrol treatment can also induce endothelial NOS (eNOS) expression ... Resveratrol significantly aggravated damage from indomethacin-induced gastric ulcers, and delayed healing, as shown by increased DS and MPO activity. The mRNA for cyclooxygenase (COX)-1, but not that for COX-2, was inhibited by resveratrol treatment, with reduced synthesis of PGE(2) by gastric tissue. However, resveratrol treatment induced eNOS gene expression and shifted the eNOS/iNOS balance. l-Arginine given before resveratrol in mice with indomethacin-induced ulcers significantly increased tissue NO synthesis and improved ulcer healing" - See L-arginine products at Amazon.com.
  • Resveratrol Prevents the Development of Pathological Cardiac Hypertrophy and Contractile Dysfunction in the SHR Without Lowering Blood Pressure - Am J Hypertens. 2009 Nov 26 - "Resveratrol treatment significantly prevented the development of concentric hypertrophy, and systolic and diastolic dysfunction in SHR without lowering blood pressure.

Thus, resveratrol may have potential in preventing cardiac impairment in patients with essential hypertension"
  • Resveratrol Modulates Tumor Cell Proliferation and Protein Translation via SIRT1-Dependent AMPK Activation - J Agric Food Chem. 2009 Nov 20 - "Similar to those effects associated with caloric restriction (CR), resveratrol has multiple beneficial activities, such as increased life span and delay in the onset of diseases associated with aging ... Here, we show that resveratrol activated AMPK in both ER-positive and ER-negative breast cancer cells ... Here, we show that resveratrol activated AMPK in both ER-positive and ER-negative breast cancer cells. Once activated, AMPK inhibited 4E-BP1 signaling and mRNA translation via mammalian target of rapamycin (mTOR). Moreover, we also found that AMPK activity mediated by resveratrol in cancer cells was due to inducing the expression of Sirtuin type 1 (SIRT1) via elevation in the cellular NAD(+)/NADH in ER-positive cells. To our knowledge, we demonstrate here for the first time that resveratrol induces the expression of SIRT1 protein in human cancer cells. These observations raise the possibility that SIRT1 functions as a novel upstream regulator for AMPK signaling and may additionally modulate tumor cell proliferation. Targeting SIRT1/AMPK signaling by resveratrol may have potential therapeutic implications for cancer and age-related diseases"
  • Effects of diverse dietary phytoestrogens on cell growth, cell cycle and apoptosis in estrogen-receptor-positive breast cancer cells - J Nutr Biochem. 2009 Oct 2 - "While genistein, resveratrol and glycitein all increased apoptosis and reduced the Bcl-2/Bax ratio, resveratrol reduced this ratio more than either genistein or glycitein. Moreover, resveratrol significantly enhanced p53-dependent transcriptional activity, but slightly reduced NF-kappaB-dependent transcriptional activity. On knockdown analysis, genistein, resveratrol and glycitein all reduced the Bcl-2/Bax ratio in the presence of apoptosis-inducing stimuli, and estrogen receptor (ER) alpha silencing had no effect on these reductions. In contrast, in the absence of apoptosis-inducing stimuli, only resveratrol reduced the ratio, and ERalpha silencing abolished this reduction. Thus, resveratrol might be the most promising candidate for HRT and chemoprevention of breast cancer due to its estrogenic activity and high antitumor activity" - See resveratrol products at Amazon.com.
  • Effect of resveratrol on helicobacter pylori-induced interleukin-8 secretion, reactive oxygen species generation and morphological changes in human gastric epithelial cells - Biol Pharm Bull. 2009 Nov;32(11):1931-5 - "preincubation of the cells with 75 and 100 muM of resveratrol significantly (p<0.05 and p<0.01 respectively) inhibited the secretion of IL-8 from H. pylori-infected cells. In addition, resveratrol pretreatment at 1-100 muM suppressed H. pylori-induced ROS generation in a concentration dependent manner. Moreover, H. pylori-initiated morphological changes were markedly blocked by resveratrol. Hence, resveratrol can be considered as a potential candidate against various H. pylori related gastric pathogenic processes" - See resveratrol products at Amazon.com.
  • Curcumin synergizes with resveratrol to inhibit colon cancer - Nutr Cancer. 2009;61(4):544-53 - "the combination of curcumin and resveratrol was found to be more effective in inhibiting growth of p53-positive (wt) and p53-negative colon cancer HCT-116 cells in vitro and in vivo in SCID xenografts of colon cancer HCT-116 (wt) cells than either agent alone. Analysis by Calcusyn software showed synergism between curcumin and resveratrol. The inhibition of tumors in response to curcumin and/or resveratrol was associated with the reduction in proliferation and stimulation of apoptosis accompanied by attenuation of NF-kappaB activity. In vitro studies have further demonstrated that the combinatorial treatment caused a greater inhibition of constitutive activation of EGFR and its family members as well as IGF-1R. Our current data suggest that the combination of curcumin and resveratrol could be an effective preventive/therapeutic strategy for colon cancer"

  • Resveratrol attenuates angiotensin II-induced interleukin-6 expression and perivascular fibrosis - Hypertens Res. 2009 Apr 17 - "Resveratrol significantly attenuated Ang II-induced IL-6 mRNA expression and IL-6 protein in the supernatant of VSMC in a dose-dependent manner. Resveratrol suppressed the IL-6 gene promoter activity. Resveratrol inhibited the Ang II-induced cAMP-response element-binding protein and nuclear factor-kappa B activity, which are critical for Ang II-induced IL-6 gene activation. An increase in the serum concentration of IL-6 induced by Ang II infusion was attenuated by an oral administration of resveratrol. Resveratrol also inhibited Ang II-induced hypertension and perivascular fibrosis of the heart. Although hydralazine reduced blood pressure level equal to resveratrol, it did not reduce the Ang II-induced IL-6 production and perivascular fibrosis. These data suggest that the inhibition of Ang II-induced vascular inflammation and high blood pressure by resveratrol may contribute, at least in part, to the anti-atherogenic effects of resveratrol"

  • Resveratrol inhibits the mTOR mitogenic signaling evoked by oxidized LDL in smooth muscle cells - Atherosclerosis. 2008 Nov 24 - "Smooth muscle cell (SMC) proliferation is a major feature in atherosclerosis, since it contributes to the formation of the fibrous cap, thus to plaque stability, but also to arterial stenosis and post-angioplasty restenosis ... These data indicate that the mTOR pathway is activated by oxLDL via PI3K/PDK1/Akt, and is required for SMC proliferation. Resveratrol blocks specifically this pathway, thereby inhibiting oxLDL-induced SMC proliferation. These data highlight a new property for resveratrol that could contribute to the general anti-atherogenic properties of this polyphenol"
  • Resveratrol protects cardiomyocytes from hypoxia-induced apoptosis through the SIRT1-FoxO1 pathway - Biochem Biophys Res Commun. 2008 Dec 3 - "Loss of cardiomyocytes through apoptosis has been proposed as a cause of ventricular remodeling and heart failure. Ischemia- and hypoxia-induced apoptosis of cardiomyocytes reportedly plays an important role in many cardiac pathologies. We investigated whether resveratrol (Res) has direct cytoprotective effects against ischemia/hypoxia for cardiomyocytes. Exposure of H9c2 embryonic rat heart-derived cells to hypoxia for 24h caused a significant increase in apoptosis, as evaluated by TUNEL and flow cytometry, while treatment with 20muM Res greatly decreased hypoxia-induced apoptosis in these cells. Exposure of the cells to Res (20muM) caused rapid activation of SIRT1, which had a dual effect on FoxO1 function: SIRT1 increased FoxO1's ability to induce cell cycle arrest, but inhibited FoxO1's ability to induce cell death. This effect could be reversed by SIRT1 inhibition. Results of our study indicate that Res inhibits hypoxia-induced apoptosis via the SIRT1-FoxO1 pathway in H9c2 cells. This polyphenol may have potential in preventing cardiovascular disease, especially in coronary artery disease (CAD) patients"

Under all stress conditions, both polyphenols increased tolerance, although their protection was more evident under peroxide exposure. By using mutant strains deficient in specific antioxidant defense systems (superoxide dismutases, catalase, or glutathione), it was observed that increased H 2O 2 tolerance produced by both polyphenols was associated with catalase, as well as the rise in survival rates caused by resveratrol under CCl 4. The acquisition of tolerance was correlated with a reduction in lipid peroxidation, indicating that the antioxidant property of resveratrol and catechin involves protection against membrane oxidation"
  • Dietary resveratrol administration increases MnSOD expression and activity in mouse brain - Biochem Biophys Res Commun. 2008 May 15 - "trans-Resveratrol (3,4',5-trihydroxystilbene; RES) ...
