Recent Longevity News for the seven days ending 12/28/11.  You should consult your doctor if you are taking any medications.

IQ isn't fixed at birth, can increase - USATODAY.com, 12/27/11 - "the average increased by 0.6 points, which correlated with an increase in IQ of 3.7 points for an addition year of schooling"

Curcumin and Piperine Prevent Remodeling of Aorta - Medscape, 12/26/11 - "N-nitro-L-arginine-methylester (L-NAME) is a nonspecific inhibitor of all three NO synthase (NOS) isoforms (neuronal - nNOS; inducible - iNOS; endothelial - eNOS) and causes an increase of blood pressure in a dose-dependent manner when administered to the experimental animals ... Administration of piperine or curcumin to animals with L-NAME-induced hypertension lead to a decrease of blood pressure, curcumin causing a more significant drop. Similar hypertension reducing effect of curcumin has been reported recently by Nakmreong et al.[34] Another study[25] registered a significant decrease of blood pressure after intravenous piperine administration. Piperine treatment was effective also in lowering blood pressure in rats with L-NAME-induced experimental hypertension described by Kumar et al.[36] The combination of curcumin and piperine in our experiment did not cause a statistically significant blood pressure decrease (with the exception of the third week) but it is apparent that it copies the course of the piperine graph curve. These differences in the results are probably related to different mechanisms of effect by the spices on blood pressure" - See curcumin products at Amazon.com and piperine at Amazon.com.

Eau de DNA: Do genes determine our perfume preference? - MSNBC, 12/23/11 - "A perfume that one person loves may be repulsive to another. The difference is in our genes" - Tell me about it.  There are at least two that are so offensive to me that I have to leave the room.  Someone said one might be the "Poison" brand perfume.  To me it smells like flea spray.

Possible cure for leukemia found in fish oil - Science Daily, 12/22/11 - "The compound -- delta-12-protaglandin J3, or D12-PGJ3 -- targeted and killed the stem cells of chronic myelogenous leukemia, or CML, in mice ... The compound is produced from EPA -- Eicosapentaenoic Acid -- an Omega-3 fatty acid found in fish and in fish oil ... During the experiments, the researchers injected each mouse with about 600 nanograms of D12-PGJ3 each day for a week. Tests showed that the mice were completely cured of the disease. The blood count was normal, and the spleen returned to normal size. The disease did not relapse ... The researchers focused on D12-PGJ3 because it killed the leukemia stem cells, but had the least number of side effects" - See Mega Twin EPA at Amazon.com.

Statin Prescriptions and Breast Cancer Recurrence Risk - Medscape, 12/22/11 - "It is possible that some past incidence studies did not observe an association because a high proportion of statin users took hydrophilic drugs. For instance, Cauley et al.[16] observed a lower risk of breast cancer among lipophilic statin users, 82% of whom took either simvastatin or lovastatin (HR = 0.82, 95% CI = 0.70 to 0.97); and Boudreau et al.[17] observed an inverse association with overall statin use, when approximately 48% of the study participants were simvastatin or lovastatin users (odds ratio = 0.7, 95% CI = 0.4 to 1.0).[17] However, Woditschka et al.[14] observed no association between statin use and breast cancer incidence in which most users were exposed to the lipophilic drugs simvastatin and lovastatin (odds ratio = 1.02, 95% CI = 0.97 to 1.08);[52] and Friis et al.[12] studied statin use and breast cancer incidence in a Danish population that overlaps with the population analyzed in our study (so simvastatin is expected to have accounted for a large proportion of the overall statin exposure) and also observed no association; (relative risk = 1.02, 95% CI = 0.76 to 1.36).[12] Although the apparent discordance between the statin associations with breast cancer incidence and recurrence may be explained by inadequate exposure characterization with respect to solubility, it is also important to realize that factors which prevent recurrence are not necessarily expected to also prevent incidence"

Menopause pill may boost sex life - USATODAY.com, 12/20/11 - "This is the first evidence that low doses of DHEA (dehydroepiandrosterone), a hormone secreted by the adrenal glands, can help sexual function as well as menopausal symptoms ... women taking DHEA had a statistically significant increase in sexual interest and activity, with similar results for women in the HRT group. Sexual activity was also higher among the women taking tiboline, but the increase was not statistically significant" - See DHEA at Amazon.com.

Scientists identify an innate function of vitamin E - Science Daily, 12/20/11 - "Everyday activities such as eating and exercise can tear the plasma membrane and the new research shows that vitamin E is essential to repair. Without repair of muscle cells, for example, muscles eventually waste away and die in a process similar to what occurs in muscular dystrophy ... Vitamin E appears to aid repair in several ways. As an antioxidant, it helps eliminate destructive byproducts from the body's use of oxygen that impede repair. Because it's lipid-soluble, vitamin E can actually insert itself into the membrane to prevent free radicals from attacking. It also can help keep phospholipids, a major membrane component, compliant so they can better repair after a tear" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

Mediterranean diet gives longer life, Swedish study suggests - Science Daily, 12/20/11 - "A Mediterranean diet with large amounts of vegetables and fish gives a longer life. This is the unanimous result of four studies to be published by the Sahlgrenska Academy ... The results show that those who eat a Mediterranean diet have a 20% higher chance of living longer"

ω-3 and ω-6 polyunsaturated fatty acid intakes and the risk of breast cancer in Mexican women: impact of obesity status - Cancer Epidemiol Biomarkers Prev. 2011 Dec 22 - "Overall, there was no significant association between ω-3 PUFA intake and breast cancer risk (p=0.31). An increased risk of breast cancer was associated with increasing ω-6 PUFA intake in pre-menopausal women (OR=1.92, 95% CI=1.13;3.26; p=0.04). A decreased risk of breast cancer was significantly associated with increasing ω-3 PUFA intake in obese women (OR=0.58, 95%CI=0.39;0.87; p=0.008), but not in normoweight nor in overweight women (p for heterogeneity = 0.017)" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

COFFEE, TEA AND SUGAR-SWEETENED CARBONATED SOFT DRINK INTAKE AND PANCREATIC CANCER RISK: A POOLED ANALYSIS OF 14 COHORT STUDIES - Cancer Epidemiol Biomarkers Prev. 2011 Dec 22 - "Sugar-sweetened carbonated soft drink (abbreviated as SSB) intake has been associated with higher circulating levels of insulin, which may promote carcinogenesis. Few prospective studies have examined SSB intake and pancreatic cancer risk; results have been heterogeneous ... pooled analysis from 14 prospective cohort studies ... No statistically significant associations were observed between pancreatic cancer risk and intake of coffee (MVRR=1.10, 95% CI=0.81-1.48 comparing >900 to <0g/day; 237g≈8oz), tea (MVRR=0.96, 95% CI=0.78-1.16 comparing >400 to 0g/day; 237g≈8oz) or SSB (MVRR=1.19, 95% CI=0.98-1.46 comparing >250 to 0g/day; 355g≈12oz) (p-value, test for between-studies heterogeneity >0.05). These associations were consistent across levels of sex, smoking status and body mass index. When modeled as a continuous variable, a positive association was evident for SSB (MVRR=1.06, 95% CI=1.02-1.12)" - Big change compared to this study:

A Low-Glycemic Load Diet Reduces Serum C-Reactive Protein and Modestly Increases Adiponectin in Overweight and Obese Adults - J Nutr. 2011 Dec 21 - "Among participants with high-body fat mass (>32.0% for males and >25.0% for females), the low-GL diet reduced CRP (P = 0.02) and marginally increased adiponectin (P = 0.06). In conclusion, carbohydrate quality, independent of energy, is important. Dietary patterns emphasizing low-GL foods may improve the inflammatory and adipokine profiles of overweight and obese individuals"

Diet Quality Is Associated with All-Cause Mortality in Adults Aged 65 Years and Older - J Nutr. 2011 Dec 21 - "Three measures of diet quality were used: the Healthy Diet Score (HDS), the Recommended Food Score (RFS), and the Mediterranean Diet Score (MDS) ... After adjustment for confounders, the MDS was significantly associated with mortality [highest vs. lowest quartile; HR = 0.78 (95% CI = 0.62-0.98)]. Similarly, the RFS was also associated with mortality [HR = 0.67 (95 % CI = 0.52-0.86)]; however, there were no significant associations for the HDS [HR = 0.99 (95% CI = 0.79-1.24)]"

Effect of vitamin d supplementation on muscle strength, gait and balance in older adults: a systematic review and meta-analysis - J Am Geriatr Soc. 2011 Dec;59(12):2291-300 - "Supplemental vitamin D with daily doses of 800 to 1,000 IU consistently demonstrated beneficial effects on strength and balance. An effect on gait was not demonstrated, although further evaluation is recommended" - See vitamin D at Amazon.com.

Testosterone therapy decreased subcutaneous fat and adiponectin in ageing men - Eur J Endocrinol. 2011 Dec 21 - "Our data showed that testosterone therapy decreased subcutaneous fat on the abdomen and lower extremities, but had no significant effect on visceral fat. Moreover, adiponectin levels were significantly decreased during testosterone therapy"

Fruit, vegetables, fibre and micronutrients and risk of US renal cell carcinoma - Br J Nutr. 2011 Dec 20:1-9 - "Intake of vegetables was associated with a decreased risk of RCC (OR 0.5; 95 % CI 0.3, 0.7; Ptrend = 0.002), (top compared to the bottom quartile of intake). When intake of individual nutrients was investigated, vegetable fibre intake was associated with decreased risks (OR 0.4; 95 % CI 0.2, 0.6; P < 0.001), but this was not the case with fruit fibre (OR 0.7; 95 % CI 0.4, 1.1) or grain fibre (OR 1.0; 95 % CI 0.6, 1.5). β-Cryptoxanthin and lycopene were also associated with decreased risks, but when both were included in a mutually adjusted backwards stepwise regression model, only β-cryptoxanthin remained significant (OR 0.5; 95 % CI 0.3, 0.8). When other micronutrients and types of fibre were investigated together, only vegetable fibre and β-cryptoxanthin had significant trends (P < 0.01) (OR 0.6; 95 % CI 0.3, 0.9) (OR 0.5; 95 % CI 0.3, 0.9), respectively. These findings were stronger in those aged over 65 years (Pinteraction = 0.001). Among non-smokers, low intake of cruciferous vegetables and fruit fibre was also associated with increased risk of RCC (Pinteraction = 0.03); similar inverse associations were found for β-cryptoxanthin, lycopene and vitamin C. When nutrients were mutually adjusted by backwards regression in these subgroups, only β-cryptoxanthin remained associated with lower RCC risk"

Macronutrients, vitamins and minerals intake and risk of esophageal squamous cell carcinoma: a case-control study in Iran - Nutr J. 2011 Dec 20;10(1):137 - "ESCC cases consumed significantly more hot foods and beverages and fried and barbecued meals, compared to the controls (p<0.05). After adjusting for potential confounders, the risk of ESCC increased significantly in the highest tertiles of saturated fat [OR:2.88,95%CI:1.15-3.08], cholesterol [OR:1.53, 95%CI: 1.41-4.13], discretionary calorie [OR:1.51, 95%CI: 1.06-3.84], sodium [OR:1.49,95%CI:1.12-2.89] and total fat intakes [OR:1.48, 95%CI:1.09-3.04]. In contrast, being in the highest tertile of carbohydrate, dietary fiber and (n-3) fatty acid intake reduced the ESCC risk by 78%, 71% and 68%, respectively. The most cancer-protective effect was observed for the combination of high folate and vitamin E intakes (OR: 0.02, 95%CI: 0.00-0.87; p<0.001). Controls consumed 623.5 times higher selenium, 5.48 times as much beta-carotene and 1.98 times as much alpha-tocopherol as the amount ESCC cases consumed"

  • B-DIM Impairs Radiation-Induced Survival Pathways Independently of Androgen Receptor Expression and Augments Radiation Efficacy in Prostate Cancer - Cancer Lett. 2011 Dec 9 - "Increased consumption of cruciferous vegetables is associated with decreased risk in prostate cancer (PCa). The active compound in cruciferous vegetables appears to be the self dimerized product [3,3'-diindolylmethane (DIM)] of indole-3-carbinol (I3C). Nutritional grade B-DIM (absorption-enhanced) has proven safe in a Phase I trial in PCa ... B-DIM inhibited cell growth in a dose-dependent manner in both PC-3 (AR-) and C4-2B (AR+) cell lines. B-DIM was effective at increasing radiation-induced cell killing in both cell lines, independently of AR expression. B-DIM inhibited NF-κB and HIF-1α DNA activities and blocked radiation-induced activation of these transcription factors in both PC-3 and C4-2B cells. In C4-2B (AR+) cells, AR expression and nuclear localization were significantly increased by radiation. However, B-DIM abrogated the radiation-induced AR increased expression and trafficking to the nucleus, which was consistent with decreased PSA secretion. In vivo, treatment of PC-3 prostate tumors in nude mice with B-DIM and radiation resulted in significant primary tumor growth inhibition and control of metastasis to para-aortic lymph nodes. These studies demonstrate that B-DIM augments radiation-induced cell killing and tumor growth inhibition. B-DIM impairs critical survival signaling pathways activated by radiation, leading to enhanced cell killing. These novel observations suggest that B-DIM could be used as a safe compound to enhance the efficacy of radiotherapy for castrate-resistant PCa" - See diindolylmethane at Amazon.com.
  • You are what you eat: Low fat diet with fish oil slows growth of human prostate cancer cells, study suggests - Science Daily, 10/25/11 - "Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet ... The short-term study also found that blood obtained from patients after the low-fat, fish oil diet slowed the growth of prostate cancer cells in a test tube, while blood from men on the Western diet did not slow cancer growth ... Preclinical studies suggest that lowering dietary omega-6 fatty acids from corn oil and increasing omega-3 fatty acids from fish oil decreases the risk of prostate cancer development and progression," the study states. "We found this diet intervention resulted in a decrease in omega-6 vs. omega-3 fatty acid ratios in benign and malignant prostate tissue and a decrease in malignant cell proliferation" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Vitamin E and the risk of prostate cancer: the Selenium and Vitamin E Cancer Prevention Trial (SELECT) - JAMA. 2011 Oct 12;306(14):1549-56 - "Oral selenium (200 μg/d from L-selenomethionine) with matched vitamin E placebo, vitamin E (400 IU/d of all rac-α-tocopheryl acetate) with matched selenium placebo, both agents, or both matched placebos for a planned follow-up of a minimum of 7 and maximum of 12 years ... This report includes 54,464 additional person-years of follow-up and 521 additional cases of prostate cancer since the primary report. Compared with the placebo (referent group) in which 529 men developed prostate cancer, 620 men in the vitamin E group developed prostate cancer (hazard ratio [HR], 1.17; 99% CI, 1.004-1.36, P = .008); as did 575 in the selenium group (HR, 1.09; 99% CI, 0.93-1.27; P = .18), and 555 in the selenium plus vitamin E group (HR, 1.05; 99% CI, 0.89-1.22, P = .46). Compared with placebo, the absolute increase in risk of prostate cancer per 1000 person-years was 1.6 for vitamin E, 0.8 for selenium, and 0.4 for the combination" - Note:  The study used rac-α-tocopheryl acetate.  See my vitamin E page for several articles regarding taking only one of the  eight forms of vitamin E.  See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.
  • Zyflamend Reduces the Expression of Androgen Receptor in a Model of Castrate-Resistant Prostate Cancer - Nutr Cancer. 2011 Sep 29 - "These results demonstrated that Zyflamend inhibited IGF-1-stimulated cell growth, IGF-1R expression, and androgen receptor expression and its nuclear localization, but these effects were not dependent upon phosphatidylinositol 3-kinase/pAKT signaling. In conclusion, Zyflamend decreased cell proliferation and inhibited IGF-1R and androgen receptor expression in a phosphatidylinositol 3-kinase/pAKT independent manner" - See Zyflamend at Amazon.com.
  • Calcium intake and prostate cancer among African Americans: Effect modification by vitamin D receptor calcium absorption genotype - J Bone Miner Res. 2011 Sep 1 - "Compared to men in the lowest quartile of calcium intake, men in the highest quartile had an approximately two-fold increased risk of localized and advanced prostate cancer (odds ratio [OR]= 2.20, 95% confidence interval [CI]= 1.40, 3.46), with a significant dose-response. Poor absorbers of calcium (VDR Cdx2 GG genotype) had a significantly lower risk of advanced prostate cancer (OR= 0.41, 95% CI = 0.19, 0.90). The gene-calcium interaction was statistically significant (p = 0.03). Among men with calcium intake below the median (680 mg/day), carriers of the G allele had an approximately 50% decreased risk compared to men with the AA genotype. These findings suggest a link between prostate cancer risk and high intestinal absorption of calcium"
  • Associations of serum vitamin A and carotenoid levels with markers of prostate cancer detection among US men - Cancer Causes Control. 2011 Jul 29 - "Associations of serum vitamin A and carotenoid levels with markers of prostate cancer detection were evaluated among 3,927 US men, 40-85 years of age, who participated in the 2001-2006 National Health and Nutrition Examination Surveys. Five recommended definitions of prostate cancer detection were adopted using total and free prostate-specific antigen (tPSA and fPSA) laboratory measurements. Men were identified as high risk based on alternative cutoffs, namely tPSA > 10 ng/ml, tPSA > 4 ng/ml, tPSA > 2.5 ng/ml, %fPSA < 25%, and %fPSA < 15%. %fPSA was defined as (fPSA÷tPSA)× 100%. Serum levels of vitamin A (retinol and retinyl esters) and carotenoids (α-carotene, β-carotene, β-cryptoxanthin, lutein + zeaxanthin, lycopene) were defined as quartiles and examined as risk/protective factors for PSA biomarkers. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using binary logistic models. After adjustment for known demographic, socioeconomic, and lifestyle confounders, high serum levels of retinyl esters (tPSA > 10 ng/ml: Q4 vs. Q1 → OR = 0.38, 95% CI: 0.14-1.00) and α-carotene (%fPSA < 15%: Q4 vs. Q1 → OR = 0.49, 95% CI: 0.32-0.76) were associated with a lower odds, whereas high serum level of lycopene (tPSA > 2.5 ng/ml: Q4 vs. Q1 → OR = 1.49, 95% CI: 1.01-2.14) was associated with a greater odds of prostate cancer detection. Apart from the three significant associations observed, no other exposure-outcome association was significant. Monitoring specific antioxidant levels may be helpful in the early detection of prostate cancer"
  • Impact of Consumption of Vegetable, Fruit, Grain, and High Glycemic Index Foods on Aggressive Prostate Cancer Risk - Nutr Cancer. 2011 Jul 20 - "Here we further investigate such potential relationships with a case-control study of 982 men (470 more aggressive prostate cancer cases and 512 control subjects). Comparing the highest to lowest quartiles of intake, we found that increasing intakes of leafy vegetables were inversely associated with risk of aggressive prostate cancer [adjusted odds ratio (OR) = 0.66, 95% CI: 0.46, 0.96; P trend = 0.02], as was higher consumption of high carotenoid vegetables (OR = 0.71, 95% CI: 0.48, 1.04; P trend = 0.04). Conversely, increased consumption of high glycemic index foods were positively associated with risk of aggressive disease (OR = 1.64, 95% CI: 1.05, 2.57; P trend = 0.02). These results were driven by a number of specific foods within the food groups. Our findings support the hypothesis that diets high in vegetables and low in high glycemic index foods decrease risk of aggressive prostate cancer"
  • Green Tea Extract (Epigallocatechin-3-Gallate) Reduces Efficacy of Radiotherapy on Prostate Cancer Cells - Urology. 2011 Jun 13 - "Radiotherapy is effective in inducing apoptosis in DU145 cells, but its effect was significantly reduced in the presence of EGCG, and this was associated with an increase in the induction of manganese superoxide dismutase"
  • Androgen-independent Effects of Serenoa repens Extract (Prostasan®) on Prostatic Epithelial Cell Proliferation and Inflammation - Phytother Res. 2011 Jun 8 - "Prostasan® inhibited epidermal growth factor (EGF) and lipopolysaccharide (LPS) induced proliferation of the prostatic epithelial, androgen independent cell line PC-3. At effective concentrations of 50 µg/mL, Prostasan® partly displaced EGF from EGF receptor (EGFR) but fully blocked EGF-induced cell proliferation of PC-3 cells. Similarly, Prostasan® inhibited LPS-induced proliferation of PC-3 cells without affecting LPS activation of the NFĸB pathway via toll-like receptor-4 (TLR-4). Additionally, Prostasan® reduced the constitutive secretion of monocyte chemotactic protein-1 (MCP-1), the LPS-induced secretion of IL-12 and inhibited MCP-1 and granulocyte-macrophage colony-stimulating factor (GM-CSF) production in the presence of LPS on PC-3 cells. Taken together, our results suggest that S. repens extracts, in addition to other reported effects on BPH development and prostatitis, inhibits EGF-dependent growth and proinflammatory responses of the prostate epithelial cells" - See Prostasan at Amazon.com.
  • Omega-3 Fatty Acid Inhibition of Prostate Cancer Progression to Hormone Independence Is Associated With Suppression of mTOR Signaling and Androgen Receptor Expression - Nutr Cancer. 2011 Jun 10:1-7 - "We used an in vitro model of androgen ablation to determine the effect of treatment with omega-3 fatty acids on the progression to an androgen-independent state. The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) were able to prevent progression of LNCaP cells while the omega-6 fatty acid arachidonic acid (AA) actually promoted cell growth under conditions of hormone depletion. These results correlated with a decrease in the expression of the androgen receptor as well as suppression of the Akt/mTOR signaling pathway. Connecting the mechanisms by which omega-3 fatty acids affect phenotypic outcome is important for effective exploitation of these nutrient agents as a therapeutic approach" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

The compound, polysaccharopeptide (PSP), which is extracted from the 'turkey tail' mushroom, was found to target prostate cancer stem cells and suppress tumour formation in mice ... The findings are quite significant ... Importantly, we did not see any side effects from the treatment ... He said PSP had been previously shown to possess anti-cancer properties, and 'turkey tail' mushrooms (known as Coriolus versicolor or Yun-zhi) had been widely used in Asia for medicinal benefits" - See PSP supplement at Amazon.com.
  • Coffee Consumption and Prostate Cancer Risk and Progression in the Health Professionals Follow-up Study - J Natl Cancer Inst. 2011 May 17 - "Coffee contains many biologically active compounds, including caffeine and phenolic acids, that have potent antioxidant activity and can affect glucose metabolism and sex hormone levels ... The average intake of coffee in 1986 was 1.9 cups per day. Men who consumed six or more cups per day had a lower adjusted relative risk for overall prostate cancer compared with nondrinkers (RR = 0.82, 95% confidence interval [CI] = 0.68 to 0.98, P(trend) = .10). The association was stronger for lethal prostate cancer (consumers of more than six cups of coffee per day: RR = 0.40, 95% CI = 0.22 to 0.75, P(trend) = .03). Coffee consumption was not associated with the risk of nonadvanced or low-grade cancers and was only weakly inversely associated with high-grade cancer. The inverse association with lethal cancer was similar for regular and decaffeinated coffee (each one cup per day increment: RR = 0.94, 95% CI = 0.88 to 1.01, P = .08 for regular coffee and RR = 0.91, 95% CI = 0.83 to 1.00, P = .05 for decaffeinated coffee). The age-adjusted incidence rates for men who had the highest (≥6 cups per day) and lowest (no coffee) coffee consumption were 425 and 519 total prostate cancers, respectively, per 100 000 person-years and 34 and 79 lethal prostate cancers, respectively, per 100 000 person-years"
  • Coffee may reduce risk of lethal prostate cancer in men - Science Daily, 5/17/11 - "The researchers chose to study coffee because it contains many beneficial compounds that act as antioxidants, reduce inflammation, and regulate insulin, all of which may influence prostate cancer. Coffee has been associated in prior studies with a lower risk of Parkinson's disease, type 2 diabetes, gallstone disease, and liver cancer or cirrhosis ... Men who consumed the most coffee (six or more cups daily) had nearly a 20% lower risk of developing any form of prostate cancer ... Men who drank the most coffee had a 60% lower risk of developing lethal prostate cancer ... Even drinking one to three cups of coffee per day was associated with a 30% lower risk of lethal prostate cancer"
  • Aspirin reduces the risk of cancer recurrence in prostate cancer patients, study suggests - Science Daily, 5/2/11 - "After 10-years from completion of treatment, 31% of the men who took aspirin developed recurrence compared with 39% of non-aspirin users (p=0.0005). There was also a 2% improvement in 10-year prostate cancer related survival associated with aspirin use with a trend toward statistical significance"
  • Thiazolidenediones induce tumour-cell apoptosis through the Akt-GSK3β pathway - J Clin Pharm Ther. 2011 Mar 16 - "Prostate cancer is a major health threat for men. Thiazolidenediones (TZDs) are synthetic ligands of the peroxisome proliferator-activated receptor γ (PPARγ), and previous studies have shown that TZDs induce apoptosis of prostate cancer cells independently of PPARγ activation. However, the exact mechanism of these effects remains unknown ... The apoptosis-inducing effect of TZDs on prostate cancer cells involves the inhibition of Akt phosphorylation. Furthermore, TZDs induce inactivation of GSK3β, a multifunctional kinase that mediates essential events promoting prostate cancer development and acquisition of androgen independence. In addition, the GSK3β inhibitor lithium chloride sensitizes prostate cancer cells to TZDs cytotoxicity. What is new and Conclusion:  Our data suggest that modulation of Akt-GSK3β pathway is involved in the cell death pathway engaged by TZDs in prostate cancer cells.

  • Gamma-tocotrienol induces apoptosis and autophagy in prostate cancer cells by increasing intracellular dihydrosphingosine and dihydroceramide - Int J Cancer. 2011 Mar 11 - "Although cell-based studies have shown that γ-tocotrienol (γTE) exhibits stronger anticancer activities than other forms of vitamin E including γ-tocopherol (γT), the molecular bases underlying γTE-exerted effects remains to be elucidated ... In agreement with these cell-based studies, γTE inhibited LNCaP xenograft growth by 53% (P<0.05), compared with 33% (P = 0.07) by γT, in nude mice. These findings provide a molecular basis of γTE-stimulated cancer-cell death and support the notion that elevation of intracellular dihydroceramide and dihydrosphingosine is likely a novel anticancer mechanism" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

  • Chemopreventative Potential of the Cruciferous Vegetable Constituent Phenethyl Isothiocyanate in a Mouse Model of Prostate Cancer - J Natl Cancer Inst. 2011 Feb 17 - "This study was undertaken to determine the chemopreventative efficacy of phenethyl isothiocyanate (PEITC), a bioactive constituent of many edible cruciferous vegetables, in a mouse model of prostate cancer, and to identify potential biomarker(s) associated with PEITC response ... Administration of PEITC (3 μmol/g diet) decreased incidence (PEITC diet vs control diet, mean = 21.65 vs 57.58%, difference = -35.93%, 95% confidence interval = -45.48% to -13.10%, P = .04) as well as burden (affected area) (PEITC diet vs control diet, mean = 18.53% vs 45.01%, difference = -26.48%, 95% confidence interval = -49.78% to -3.19%, P = .02) of poorly differentiated tumors in the dorsolateral prostate of transgenic mice compared with control mice, with no toxic effects. PEITC-mediated inhibition of prostate carcinogenesis was associated with induction of autophagy and overexpression of E-cadherin in the dorsolateral prostate. However, PEITC treatment was not associated with a decrease in cellular proliferation, apoptosis induction, or inhibition of neoangiogenesis. Plasma proteomics revealed distinct changes in the expression of several proteins (eg, suppression of clusterin protein) in the PEITC-treated mice compared with control mice. Conclusions In this transgenic model, dietary PEITC suppressed prostate cancer progression by induction of autophagic cell death. Potential biomarkers to assess the response to PEITC treatment in plasma were identified" - See cruciferous supplements at Amazon.com.

  • Soy isoflavones in conjunction with radiation therapy in patients with prostate cancer - Nutr Cancer. 2010 Oct;62(7):996-1000 - "Soy isoflavones sensitize prostate cancer cells to radiation therapy by inhibiting cell survival pathways activated by radiation. At the same time, soy isoflavones have significant antioxidant and anti-inflammatory activity, which may help prevent the side effects of radiation ... Adverse effects of radiation therapy on bladder, bowel, and sexual function were assessed by a self-administered quality of life questionnaire at 3 and 6 mo. Only 26 and 27 patients returned completed questionnaires at 3 and 6 mo, respectively. At each time point, urinary, bowel, and sexual adverse symptoms induced by radiation therapy were decreased in the soy isoflavone group compared to placebo group. At 3 mo, soy-treated patients had less urinary incontinence, less urgency, and better erectile function as compared to the placebo group. At 6 mo, the symptoms in soy-treated patients were further improved as compared to the placebo group. These patients had less dripping/leakage of urine (7.7% in Group 1 vs. 28.4% in Group 2), less rectal cramping/diarrhea (7.7% vs. 21.4%), and less pain with bowel movements (0% vs. 14.8%) than placebo-treated patients. There was also a higher overall ability to have erections (77% vs. 57.1%).

An increased risk was also observed with increasing intake of sucrose and disaccharides. In contrast, men in the highest quartile of cholesterol intake were at lower risk of PCa. No association was found with intake of total proteins, total fat, monounsaturated fats, polyunsaturated fats, monosaccharides, and total carbohydrates. The findings provide evidence that a diet low in trans fat could reduce PCa risk"
  • Mixed Tocotrienols Inhibit Prostate Carcinogenesis in TRAMP Mice - Nutr Cancer. 2010 Aug;62(6):789-94 - "mixed-tocotrienol-fed groups had a lower incidence of tumor formation along with a significant reduction in the average wet weight of genitourinary apparatus. Furthermore, mixed tocotrienols significantly reduced the levels of high-grade neoplastic lesions as compared to the positive controls. This decrease in levels of high-grade neoplastic lesions was found to be associated with increased expression of proapoptotic proteins BAD (Bcl(2) antagonist of cell death) and cleaved caspase-3 and cell cycle regulatory proteins cyclin dependent kinase inhibitors p21 and p27. In contrast, the expression of cyclins A and E were found to be decreased in mixed-tocotrienol groups. Taken together, our results show that by modulating cell cycle regulatory proteins and increasing expression of proapoptotic proteins, mixed tocotrienols suppress prostate tumorigenesis in the TRAMP mice" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

  • Gamma-tocotrienol as an effective agent in targeting prostate cancer stem cell-like population - Int J Cancer. 2010 Jul 8 - "Emerging evidence supports that prostate cancer originates from a rare sub-population of cells, namely prostate cancer stem cells (CSCs). Conventional therapies for prostate cancer are believed to mainly target the majority of differentiated tumor cells but spare CSCs, which may account for the subsequent disease relapse after treatment. Therefore, successful elimination of CSCs may be an effective strategy to achieve complete remission from this disease. Gamma-tocotrienols (gamma-T3) is one of the vitamin-E constituents which have been shown to have anticancer effects against a wide-range of human cancers. Recently, we have reported that gamma-T3 treatment not only inhibits prostate cancer cell invasion but also sensitizes the cells to docetaxel-induced apoptosis, suggesting that gamma-T3 may be an effective therapeutic agent against advanced stage prostate cancer. Here, we demonstrate for the first time that gamma-T3 can down-regulate the expression of prostate CSC markers (CD133/CD44) in androgen independent (AI) prostate cancer cell lines (PC-3 & DU145), as evident from western blotting analysis. Meanwhile, the spheroid formation ability of the prostate cancer cells was significantly hampered by gamma-T3 treatment. In addition, pre-treatment of PC-3 cells with gamma-T3 was found to suppress tumor initiation ability of the cells. More importantly, while CD133-enriched PC-3 cells were highly resistant to docetaxel treatment, these cells were as sensitive to gamma-T3 treatment as the CD133-depleted population. Our data suggest that gamma-T3 may be an effective agent in targeting prostate CSCs, which may account for its anticancer and chemosensitizing effects reported in previous studies" - See Jarrow FamilE (contains all eight members of the vitamin E family, includes Tocomin) at Amazon.com.

  • Effects of phenylethyl isothiocyanate and its metabolite on cell-cycle arrest and apoptosis in LNCaP human prostate cancer cells - Int J Food Sci Nutr. 2010 May;11(7):324-36 - "Cruciferous vegetable consumption is associated with decreased risk of several cancers, including prostate cancer. Gluconasturtiin, one of the predominant glucosinolates in cruciferous vegetables, is hydrolyzed to yield phenylethyl isothiocyanate (PEITC). PEITC absorption and metabolism in humans involves glutathione conjugation followed by conversion via the mercapturic acid pathway to an N-acetylcysteine (NAC) conjugate that is excreted in the urine. We observed an inhibitory effect of PEITC and its metabolite, NAC-PEITC, on cancer cell proliferation, cell-cycle progression, and apoptosis in LNCaP human prostate cancer cells. PEITC and NAC-PEITC suppressed LNCaP cell proliferation in a dose-dependent manner, and exposure to 5 microM PEITC or NAC-PEITC reduced cell proliferation by 25% and 30%, respectively. Cell-cycle analysis revealed that cells treated with 5 microM PEITC or NAC-PEITC arrested at the G(2)/M phase. In addition, the percentage of cells in the S phase decreased from 46% to 25% following 48 h of incubation with PEITC or NAC-PEITC. The G(2)/M-phase cell-cycle arrest of LNCaP cells grown in the presence of PEITC or NAC-PEITC is correlated with the downregulation of Cdk1 and cyclin B(1) protein expression. Apoptosis was observed at the later stages of 24-h and 48-h treatments with 5 microM PEITC and NAC-PEITC. In conclusion, PEITC and NAC-PEITC are potential chemopreventive/chemotherapeutic agents against LNCaP human prostate cancer cells"

  • 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.

  • Intakes of meat, fish, poultry, and eggs and risk of prostate cancer progression - Am J Clin Nutr. 2009 Dec 30 - "Intakes of processed and unprocessed red meat, fish, total poultry, and skinless poultry were not associated with prostate cancer recurrence or progression. Greater consumption of eggs and poultry with skin was associated with 2-fold increases in risk in a comparison of extreme quantiles: eggs [hazard ratio (HR): 2.02; 95% CI: 1.10, 3.72; P for trend = 0.05] and poultry with skin (HR: 2.26, 95% CI: 1.36, 3.76; P for trend = 0.003). An interaction was observed between prognostic risk at diagnosis and poultry. Men with high prognostic risk and a high poultry intake had a 4-fold increased risk of recurrence or progression compared with men with low/intermediate prognostic risk and a low poultry intake (P for interaction = 0.003). CONCLUSIONS: Our results suggest that the postdiagnostic consumption of processed or unprocessed red meat, fish, or skinless poultry is not associated with prostate cancer recurrence or progression, whereas consumption of eggs and poultry with skin may increase the risk"
