Recent Longevity News for the seven days ending 2/17/10.  You should consult your doctor if you are taking any medications.

High levels of vitamin D in older people can reduce heart disease and diabetes - Science Daily, 2/16/10 - "Researchers looked at 28 studies including 99,745 participants across a variety of ethnic groups including men and women. The studies revealed a significant association between high levels of vitamin D and a decreased risk of developing cardiovascular disease (33% compared to low levels of vitamin D), type 2 diabetes (55% reduction) and metabolic syndrome (51% reduction)" - See vitamin D at Amazon.com.

Fox segment on halitosis, recommends SmartMouth brand, just in time for Valentine's (video) - 2/13/10 - See SmartMouth Alcohol-Free Mouthwash, Fresh Mint, 16-Ounce Box (Pack of 2) and SmartMouth Toothpaste, 6-Ounce Tubes (Pack of 3) at Amazon.com.

Dietary formula that maintains youthful function into old age - Science Daily, 2/12/10 - "Using bagel bits soaked in the supplement to ensure consistent and accurate dosing, the formula maintained youthful levels of locomotor activity into old age whereas old mice that were not given the supplement showed a 50 per cent loss in daily movement, a similar dramatic loss in the activity of the cellular furnaces that make our energy, and declines in brain signaling chemicals relevant to locomotion. This builds on the team's findings that the supplement extends longevity, prevents cognitive declines, and protects mice from radiation ... Ingredients consists of items that were purchased in local stores selling vitamin and health supplements for people, including vitamins B1, C, D, E, acetylsalicylic acid, beta carotene, folic acid, garlic, ginger root, ginkgo biloba, ginseng, green tea extract, magnesium, melatonin, potassium, cod liver oil, and flax seed oil" - Sounds like most of what I'm already taking. - Ben

About ten years ago I did a lot of reading on Dr. Judah Folkman and Angiostatin, Endostatin & other anti-angiogenesis drugs and started that webpage on it.  What really caught my eye with Dr, Folkman's research was a picture of a mouse with a tumor the size of it's head that was fully cured by angiostatin.  They had problems duplicating it in humans though.  Someone sent these articles and they seem to be picking up research on it again:

  • TED 2010: Halting Blood Vessels Key to New Cancer Treatment; Possibly Obesity - wired.com, 2/10/10 - "What he found was that nature has laced a large number of foods, beverages and herbs with naturally occurring inhibitors of angiogenesis ... He and his researchers built a simulator to test the effect different foods (see list of foods at right) would have on blood vessels at concentrations that are available through eating, rather than concentrated, encapsulated forms. The tests showed that an extract of resveratrol, found in red grapes and red wine, would inhibit abnormal angiogenesis by 60 percent. Extracts from strawberries and soybeans had similar benefits ... They also tested four teas — a Chinese jasmine tea, Japanese sencha, Earl Gray and a blend of the Chinese jasmine and Japanese sencha teas. The teas varied in their potencies. The Chinese Jasmine and Japanese sencha teas were each less potent than the Earl Grey tea. But when they combined the two teas, the combination was more potent than either one alone or than the Earl Grey tea. This means there’s food synergy, Li said, and that foods likely work best in combination to create benefits"
  • Highlights from TED 2010, Wednesday: "We can eat to starve cancer" - boingboing.net, 2/10/10 - "Angiogenesis means the growth of blood vessels. Your body usually knows how to regulate the growth of blood vessels, but sometimes there are defects in blood growing and pruning. Too little angiogenesis can lead to things like wounds that won't heal, heart attack, and other diseases. Too much angiogenesis leads to other bad things such as blindness, arthritis. It's is a common denominator of many diseases. It's also the "hallmark of every type of cancer." ... In autopsies of people who died in car accidents, doctors have found microscopic cancers in 40% of woman (breast) and 40% of men (prostate). Something like 70% of older people have microcancers in their thyroid. But the cancer is harmless -- "cancer without disease." If you block angiogenesis the cancer can't grow. "It's a tipping point between harmless cancer and deadly one.""

  • Dog's tale of survival opens door in cancer research - USA Today, 7/24/02 - "The treatment is a cocktail of so-called anti-angiogenic drugs, which have been widely researched for more than a decade and work by starving tumors of their blood supply. Researchers say the three-drug combination, which Haber mixed into Navy's regular dog food, targets the cancer from many angles ... When researchers heard that Navy was cancer-free after receiving a cocktail of drugs already approved by the Food and Drug Administration — Celebrex, tamoxifen (sold as Nolvadex) and doxycycline — the treatment became known as the Navy Protocol ... Navy's treatment, though experimental, cost $2,000"

DHA omega-3 may improve chemotherapy outcomes: Study - Nutra USA, 2/10/10 - "Our data show for the first time that a dietary intervention targeted on DHA is a feasible approach that has potential to substantially increase survival in metastatic breast cancer patients treated with chemotherapy ... the overall survival of women was 22 months, and reached 34 months in women with the highest DHA levels in their blood" - [Abstract] - See Jarrow Max DHA at Amazon.com.

Dry Cleaning Chemical 'Likely' Causes Cancer - WebMD, 2/9/10 - "PERC is a chemical known as perchloroethylene or tetrachloroethylene. It's the solvent used by about 85% of U.S. dry cleaners ... In 2008, the Environmental Protection Agency (EPA) suggested that PERC be classified as a "likely human carcinogen." Moreover, the EPA found that PERC's most dangerous noncancer toxicity is brain and nervous system damage -- and set safe exposure levels well below levels that cause such damage"

Lycopene effects contributing to prostate health - Nutr Cancer. 2009 Nov;61(6):775-83 - "Epidemiological evidence links lycopene consumption with decreased prostate cancer risk ... Lycopene modulates several of the aforementioned pathways, providing a promising rationale for prostate cancer risk reduction by lycopene: In many experimental setups, lycopene reduced inflammatory signals, prevented oxidative DNA damage, modulated the expression or activity of IGF axis members, of Wnt/beta-catenin and androgen signalling, and enhanced gap junctional communication. Lycopene's influence on these pathways likely contributes to the observed cell growth inhibition and apoptosis induction by lycopene. A substantial part of the lycopene effects can be explained by its antioxidant action, but other mechanisms might also be involved" - See lycopene at Amazon.com.

Lycopene in the prevention of gastrointestinal toxicity of radiotherapy - Nutr Cancer. 2009 Nov;61(6):784-8 - "The rats receiving RT only had significantly higher weight loss rate compared to the lycopene plus RT group (P = 0.001). Plasma TBARS levels after RT were also significantly higher in the RT only group compared to lycopene plus RT group (P = 0.001). In conclusion, lycopene supplementation significantly reduced the weight loss and prevented oxidative stress in rats treated with abdominopelvic radiation" - See lycopene at Amazon.com.

Synergistic role of curcumin with current therapeutics in colorectal cancer: minireview - Nutr Cancer. 2009 Nov;61(6):842-6 - "Despite the use of surgical resection and aggressive chemotherapy, nearly 50% of patients with colorectal carcinoma develop recurrent disease, highlighting the need for improved therapies. Curcumin (diferuloylmethane), the major active ingredient of turmeric (curcuma longa) with no discernable toxicity, has been shown to inhibit the growth of transformed cells and colon carcinogenesis at the initiation, promotion, and progression stages in carcinogen-induced rodent models. In a Phase I clinical trial, curcumin has been found to be extremely well tolerated and effective ... Existing data suggest that curcumin in combination with chemotherapy is a superior strategy for treatment of gastrointestinal cancer" - See curcumin products at Amazon.com.

Zinc in cancer prevention - Nutr Cancer. 2009 Nov;61(6):879-87 - "Zinc not only improves cell mediated immune functions but also functions as an antioxidant and anti-inflammatory agent. Oxidative stress and chronic inflammation have been implicated in development of many cancers. In patients with head and neck cancer, we have shown that nearly 65% of these patients were zinc deficient based on their cellular zinc concentrations. Natural killer (NK) cell activity and IL-2 generation were also affected adversely ... Zinc status also correlated with number of hospital admissions and incidences of infections. NF-kappa B is constitutively activated in many cancer cells, and this results in activation of antiapoptotic genes, VEGF, cyclin DI, EGFR, MMP-9 and inflammatory cytokines. Zinc inhibits NF-kappa B via induction of A-20. Thus, zinc supplementation should have beneficial effects on cancer by decreasing angiogenesis and induction of inflammatory cytokines while increasing apoptosis in cancer cells. Based on the above, we recommend further studies and propose that zinc should be utilized in the management and chemoprevention of cancer" - See Jarrow Zinc Balance at Amazon.com.

Successful Treatment of Severe Hypertriglyceridemia with a Formula Diet Rich in Omega-3 Fatty Acids and Medium-Chain Triglycerides - Ann Nutr Metab. 2010 Feb 12;56(3):170-175 - "Patients with highly increased plasma triglyceride levels are at risk of developing serious complications such as pancreatitis, coronary heart disease and stroke. Therefore it is important to rapidly decrease plasma triglyceride levels. A sufficient control of triglyceride levels with drugs like fibrates, statins or nicotinic acid can usually only be attained after a couple of weeks. Plasma exchange appears to be a fast but expensive method to reduce triglyceride levels. In this study we describe the use of a new omega-3 fatty acid and medium-chain triglyceride-rich formula diet as a therapeutic concept to reduce plasma triglyceride levels fast and effectively ... Thirty-two patients with severe hypertriglyceridemia were treated with the especially composed formula diet for a period of 7 days. Results: Within this period of time, plasma triglycerides decreased from 1,601 (402-4,555) to 554 (142-2,382) mg/dl (p < 0.05). Total cholesterol levels were reduced from 417 (211-841) to 287 (165-457) mg/dl (p < 0.001). Fasting glucose and uric acid levels also slightly decreased (-8%; -12%). The formula diet as a 1-week treatment was well tolerated and accepted by the patients" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

Docosahexaenoic Acid Deficiency and Prefrontal Cortex Neuropathology in Recurrent Affective Disorders - J Nutr. 2010 Feb 10 - "Increasing evidence suggests that docosahexaenoic acid [DHA, 22:6(n-3)], the principal (n-3) fatty acid in brain gray matter, has neurotrophic and neuroprotective properties. Preliminary clinical evidence also suggests that the perinatal accrual, and the subsequent dietary maintenance of, cortical DHA is positively associated with cortical gray matter volumes. The pathophysiology of recurrent affective disorders, including unipolar and bipolar depression, is associated with (n-3) fatty acid deficiency, DHA deficits, impaired astrocyte mediated vascular coupling, neuronal shrinkage, and reductions in gray matter volume in the prefrontal cortex (PFC). Preclinical studies have also observed neuronal shrinkage and indices of astrocyte pathology in the DHA-deficient rat brain. Together, this body of evidence supports the proposition that DHA deficiency increases vulnerability to neuronal atrophy in the PFC of patients with affective disorders" - See Jarrow Max DHA at Amazon.com.

Telmisartan: a Different Angiotensin II Receptor Blocker Protecting a Different Population? - J Int Med Res. 2009;37(6):1662-1679 - "Telmisartan has a unique profile among ARBs, with a high affinity for the angiotensin II type 1 receptor, a long duration of receptor binding, a high lipophilicity and a long plasma half life. This leads to sustained and powerful blood pressure lowering when compared with the first marketed ARBs, such as losartan and valsartan. Some pharmacological properties of telmisartan clearly distinguish it from other members of the ARB class and may contribute to the clinical effects seen with telmisartan. A class effect for ARBs cannot be assumed. To date, telmisartan is the only ARB that has been shown to reduce cardiovascular risk in at-risk cardiovascular patients" - Click here for reasons to consider telmisartan as a first line treatment for hypertension.  See telmisartan at OffshoreRx1.com.

Improved Survival in Patients with End-stage Cancer Treated with Coenzyme Q(10) and Other Antioxidants: a Pilot Study - J Int Med Res. 2009;37(6):1961-1971 - "This pilot study evaluated the survival of patients with end-stage cancer who received supplements of coenzyme Q(10) and a mixture of other antioxidants (e.g. vitamin C, selenium, folic acid and beta-carotene) ... Median predicted survival was 12 months (range 3 - 29 months), whereas median actual survival was 17 months (1 - 120 months), which is > 40% longer than the median predicted survival. Mean actual survival was 28.8 months versus 11.9 months for mean predicted survival. Ten patients (24%) survived for less time than predicted, whereas 31 (76%) survived for longer. Treatments were very well tolerated with few adverse effects" - See ubiquinol products at Amazon.com.

Improving outcome of chemotherapy of metastatic breast cancer by docosahexaenoic acid: a phase II trial - Br J Cancer. 2009 Dec 15;101(12):1978-85 - "The objective response rate was 44%. With a mean follow-up time of 31 months (range 2-96 months), the median TTP was 6 months. Median OS was 22 months and reached 34 months in the sub-population of patients (n = 12) with the highest plasma DHA incorporation. The most common grade 3 or 4 toxicity was neutropaenia (80%). CONCLUSION: DHA during chemotherapy was devoid of adverse side effects and can improve the outcome of chemotherapy when highly incorporated. DHA has a potential to specifically chemosensitise tumours" - See Jarrow Max DHA at Amazon.com.

Red clover extract: a source for substances that activate peroxisome proliferator-activated receptor alpha and ameliorate the cytokine secretion profile of lipopolysaccharide-stimulated macrophages - Menopause. 2010 Feb 5 - "In lipopolysaccharide-stimulated macrophages, red clover extract and its compounds reduced the secretion of proinflammatory cytokines, interleukin-6 and tumor necrosis factor alpha, increased the secretion of the anti-inflammatory interleukin-10, and/or reduced the expression of nuclear factor-kappaB, inducible nitric oxide synthase, and/or cyclooxygenase 2. Tumor necrosis factor alpha production was most efficiently reduced by biochanin A and genistein. Interleukin-6 levels were most efficiently reduced by genistein and equol. CONCLUSIONS:: Owing to its PPARalpha activation and modulation of the secreted cytokine profile, red clover extract is a putative candidate for preventing atherosclerosis and, thus, cardiovascular disease" - See Trinovin at Amazon.com.

EGCG diet also considerably lowered the levels of plasma triglyceride and liver lipid. In the epididymal white adipose tissue of EGCG diet-fed mice, the mRNA levels of adipogenic genes such as peroxisome proliferator-activated receptor-gamma (PPAR-gamma), CCAAT enhancer-binding protein-alpha (C/EBP-alpha), regulatory element-binding protein-1c (SREBP-1c), adipocyte fatty acid-binding protein (aP2), lipoprotein lipase (LPL) and fatty acid synthase (FAS) were significantly decreased. However, the mRNA levels of carnitine palmitoyl transferase-1 (CPT-1) and uncoupling protein 2 (UCP2), as well as lipolytic genes such as hormone sensitive lipase (HSL) and adipose triglyceride lipase (ATGL), were significantly increased ... These results suggest that green tea EGCG effectively reduces adipose tissue mass and ameliorates plasma lipid profiles in high-fat diet-induced obese mice. These effects might be at least partially mediated via regulation of the expression of multiple genes involved in adipogenesis, lipolysis, beta-oxidation and thermogenesis in white adipose tissue"
  • Catechin prevents endothelial dysfunction in the prediabetic stage of OLETF rats by reducing vascular NADPH oxidase activity and expression - Atherosclerosis. 2009 Feb 3 - "studies have indicated that regular intake of green tea reduces the risk of cardiovascular diseases.

  • Dietary Green Tea Extract Lowers Plasma and Hepatic Triglyceride and Decreases the Expression of Sterol Regulatory Element-Binding Protein-1c mRNA and Its Responsive Genes in Fructose-Fed Ovariectomized Rats - J Nutr. 2009 Feb 4 - "Fructose elevated plasma TG and cholesterol compared with the S group. GT at 0.5 and 1.0% markedly lowered plasma and liver TG. Fructose increased the expression of SREBP-1c, fatty acid synthase, and stearoyl-CoA desaturase 1 mRNAs in the liver, whereas GT decreased the expression of these lipogenic genes. Similarly, fructose increased the abundance of hepatic 3-hydroxy-3-methyl-glutaryl-CoA reductase mRNA, whereas GT significantly decreased its expression ... the lipid-lowering effect of GT is mediated partly by its inhibition of hepatic lipogenesis involving SREBP-1c and its responsive genes without affecting lipoprotein assembly"

Mechanisms that have been suggested as being involved in the antiatherosclerotic effects of green tea consumption primarily entail antioxidative, antiinflammatory, antiproliferative, and antithrombotic properties, as well as beneficial effects on endothelial function. Moreover, evidence exists for myocardial effects of tea constituents, including positive inotropic and antihypertrophic effects, and beneficial impact in myocardial ischaemia-reperfusion injury"
  • Epigallocatechin-3-gallate inhibits IL-6 synthesis and suppresses transsignaling by enhancing soluble gp130 production - Proc Natl Acad Sci U S A. 2008 Sep 16 - "Results from in vivo studies using a rat adjuvant-induced arthritis model showed specific inhibition of IL-6 levels in the serum and joints of EGCG-treated rats by 28% and 40%, respectively, with concomitant amelioration of rat adjuvant-induced arthritis. We also observed a marked decrease in membrane-bound gp130 protein expression in the joint homogenates of the EGCG-treated group. In contrast, quantitative RT-PCR showed that the gp130/IL-6Ralpha mRNA ratio increased by approximately 2-fold, suggesting a possible mechanism of sgp130 activation by EGCG. Gelatin zymography results showed EGCG inhibits IL-6/soluble IL-6R-induced matrix metalloproteinase-2 activity in RA synovial fibroblasts and in joint homogenates, possibly via up-regulation of sgp130 synthesis. The results of these studies provide previously undescribed evidence of IL-6 synthesis and transsignaling inhibition by EGCG with a unique mechanism of sgp130 up-regulation, and thus hold promise as a potential therapeutic agent for RA"
  • The major green tea polyphenol, (-)-epigallocatechin-3-gallate, inhibits obesity, metabolic syndrome, and Fatty liver disease in high-fat-fed mice - J Nutr. 2008 Sep;138(9):1677-83 - "In mice fed a high-fat diet (60% energy as fat), supplementation with dietary EGCG treatment (3.2 g/kg diet) for 16 wk reduced body weight (BW) gain, percent body fat, and visceral fat weight (P < 0.05) compared with mice without EGCG treatment ... EGCG treatment attenuated insulin resistance, plasma cholesterol, and monocyte chemoattractant protein concentrations in high-fat-fed mice (P < 0.05). EGCG treatment also decreased liver weight, liver triglycerides, and plasma alanine aminotransferase concentrations in high-fat-fed mice (P < 0.05). Histological analyses of liver samples revealed decreased lipid accumulation in hepatocytes in mice treated with EGCG compared with high-fat diet-fed mice without EGCG treatment. In another experiment, 3-mo-old high-fat-induced obese mice receiving short-term EGCG treatment (3.2 g/kg diet, 4 wk) had decreased mesenteric fat weight and blood glucose compared with high-fat-fed control mice (P < 0.05). Our results indicate that long-term EGCG treatment attenuated the development of obesity, symptoms associated with the metabolic syndrome, and fatty liver. Short-term EGCG treatment appeared to reverse preexisting high-fat-induced metabolic pathologies in obese mice. These effects may be mediated by decreased lipid absorption, decreased inflammation, and other mechanisms"

  • (-)-Epigallocatechin-3-gallate (EGCG) inhibits HGF-induced invasion and metastasis in hypopharyngeal carcinoma cells - Cancer Lett. 2008 Jul 14 - "Hepatocyte growth factor (HGF) has recently attracted a considerable amount of attention as a stromal-derived mediator in tumor-stromal interactions, particularly because of its close involvement in cancer invasion and metastasis, and (-)-epigallocatechin-3-gallate (EGCG) can modulate the cell signaling associated with angiogenesis, metastasis, and migration of cancer cells ... EGCG at physiologically relevant concentration (1muM) suppressed HGF-induced tumor motility and MMP-9 and uPA activities, and the suppression of Akt and Erk pathway by EGCG was one of the downstream mechanisms to facilitate EGCG-induced anti-invasion effects. These results suggest that EGCG may serve as a therapeutic agent to inhibit HGF-induced invasion in hypopharyngeal carcinoma patients" - I took six capsules per day of green tea extract when I had my neck cancer.  Maybe that's what saved me.  See green tea extract at Amazon.com.
