Powerful Advances in Natural Cancer Prevention - Life Extension - 0 views

  •  
    Scientists have known that cruciferous vegetables contain a host of chemopreventive agents that act in many different ways to block cancer development.2 Key among these products are indole-3-carbinol (I3C) and sulforaphane.1,3 Cancer cells need a brisk blood supply to support their rampant growth and reproduction. Preliminary studies in vitro and in vivo have found that apigenin inhibits blood vessel growth (angiogenesis) in human ovarian cancer cells, blocking production of two main signaling molecules required to stimulate vessel growth.20,21 Scientists confirmed this effect in ovarian cancer cells, also finding that apigenin strongly inhibits cell proliferation.22 Apigenin and BITC: Complementary Cancer Protection Cancer cells also need energy to support their frenetic reproductive activity. Researchers applied apigenin to human pancreatic cancer cells in culture and studied the cells' uptake of glucose.14 Astonishingly, they found that apigenin deprived energy-hungry cancer cells of glucose to support their voracious appetites and aggressive growth. It did this by down-regulating vital glucose-transporting proteins in cancer cells. This approach could effectively starve deadly cancer cells and stop them in their tracks. Another cruciferous vegetable component receiving rave reviews is the sulfur-containing molecule benzyl isothiocyanate, or BITC (pronounced "bitsy"). As with apigenin, population studies have shown that higher intakes of BITC correlate with reduced risk of cancers of the lung, breast, and colon30 while blocking cancer development in a host of different ways. BITC induces breast cancer cell death by apoptosis (programmed cell death), interfering with cancer cells' energy utilization and causing them to die off before they can contribute to tumor growth.31,32 In human ovarian cancer cells, BITC induces apoptosis by a different mechanism. It stimulates "signaling" molecules that tell cancer cells it's time to close up shop.

    The effect of omega-3 FAs on tumour angiogenesis and their therapeutic potential. Spencer L, Mann C, Metcalfe M, Webb M, Pollard C, Spencer D, Berry D, Steward W, Dennison A. Eur J Cancer. 2009 Aug;45(12):2077-86. Epub 2009 Jun 1. Review. PMID: 19493674 Omega-3 fatty acid (omega-3 FA) consumption has long been associated with a lower incidence of colon, breast and prostate cancers in many human populations. Human trials have demonstrated omega-3 FA to have profound anti-inflammatory effects in those with cancer. In vitro and small animal studies have yielded a strong body of evidence establishing omega-3 FA as having anti-inflammatory, anti-apoptotic, anti-proliferative and anti-angiogenic effects. This review explores the evidence and the mechanisms by which omega-3 FA may act as angiogenesis inhibitors and identifies opportunities for original research trialling omega-3 FAs as anti-cancer agents in humans. The conclusions drawn from this review suggest that omega-3 FAs in particular eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found principally in oily fish have potent anti-angiogenic effects inhibiting production of many important angiogenic mediators namely; Vascular Endothelial Growth Factor (VEGF), Platelet-Derived Growth Factor (PDGF), Platelet-Derived Endothelial Cell Growth Factor (PDECGF), cyclo-oxygenase 2 (COX-2), prostaglandin-E2 (PGE2), nitric oxide, Nuclear Factor Kappa Beta (NFKB), matrix metalloproteinases and beta-catenin

New data on link between cancer and nutrition discussed at European symposium - 0 views

  •  
    European experts in cancer and nutrition are meeting in Zurich, Switzerland late this month to discuss cutting-edge research in one of the most important and fiercely debated topics in cancer prevention: the link between diet and cancer. There is growing evidence that many cancers may be prevented through healthy lifestyle, including a nutritionally balanced diet. In addition, nutritional problems can also have a negative impact on cancer management and the lives of patients. Other presentations will include new data on topics such as: Childhood nutrition and later breast cancer risk The anti-tumour effects of green tea Malnutrition and patient distress in cancer Possible anti-tumour effects of soy extracts in mice Estrogens in beef and cancer risk

    Berberine, a natural product, induces G1-phase cell cycle arrest and caspase-3-dependent apoptosis in human prostate carcinoma cells. Mantena SK, Sharma SD, Katiyar SK. Mol Cancer Ther. 2006 Feb;5(2):296-308. PMID: 16505103 doi: 10.1158/1535-7163.MCT-05-0448 The effectiveness of berberine in checking the growth of androgen-insensitive, as well as androgen-sensitive, prostate cancer cells without affecting the growth of normal prostate epithelial cells indicates that it may be a promising candidate for prostate cancer therapy. The evaluation of ancient herbal medicines may indicate novel strategies for the treatment of prostate cancer, which remains the leading cause of cancer-related deaths in American men (1). In our present investigation, we show that a naturally occurring isoquinoline alkaloid, berberine, significantly inhibits the proliferation and reduces the viability of DU145 and PC-3 as well as LNCaP cells (Fig. 1), which suggests that berberine may be an effective chemotherapeutic agent against both androgen-sensitive and androgen-insensitive prostate cancer cells. Importantly, we found that berberine did not exhibit toxicity to nonneoplastic human prostate epithelial cells under the conditions used, except for a moderate reduction in cell viability at higher concentrations when cells were treated in vitro for an extended period of time. In conclusion, the results of the present study indicate that berberine inhibits proliferation and induces G1-phase arrest and apoptosis in human prostate cancer cells but not in normal human prostate epithelial cells. In addition, we provide mechanistic evidence that berberine-induced apoptosis in prostate carcinoma cells, particularly hormone-refractory prostate carcinoma cells, is mediated through enhanced expression of Bax, disruption of the mitochondrial membrane potential, and activation of caspase-3.

    Berberine suppresses in vitro migration and invasion of human SCC-4 tongue squamous cancer cells through the inhibitions of FAK, IKK, NF-kappaB, u-PA and MMP-2 and -9. Ho YT, Yang JS, Li TC, Lin JJ, Lin JG, Lai KC, Ma CY, Wood WG, Chung JG. Cancer Lett. 2009 Jul 8;279(2):155-62. Epub 2009 Feb 28. PMID: 19251361 doi:10.1016/j.canlet.2009.01.033 There is increasing evidence that urokinase-type plasminogen activator (u-PA) and matrix metalloproteinases (MMPs) play an important role in cancer metastasis and angiogenesis. Inhibition of u-PA and MMPs could suppress migration and invasion of cancer cells. Berberine, one of the main constituents of the plant Rhizoma coptidis, is a type of isoquinoline alkaloid, reported to have anti-cancer effects in different human cancer cell lines. There is however, no available information on effects of berberine on migration and invasion of human tongue cancer cells. Here, we report that berberine inhibited migration and invasion of human SCC-4 tongue squamous carcinoma cells. This action was mediated by the p-JNK, p-ERK, p-p38, IκK and NF-κB signaling pathways resulting in inhibition of MMP-2 and -9 in human SCC-4 tongue squamous carcinoma cells. Our Western blowing analysis also showed that berberine inhibited the levels of urokinase-plasminogen activator (u-PA). These results suggest that berberine down-regulates u-PA, MMP-2 and -9 expressions in SCC-4 cells through the FAK, IKK and NF-κB mediated pathways and a novel function of berberine is to inhibit the invasive capacity of malignant cells.

Cancer Journal: Latest cancer research Link between cancer and dietary restriction | ec... - 0 views

  •  
    A signalling pathway that influences how sensitive cancer cells are to the beneficial effects of dietary restriction is described in this week's Nature. Dietary restriction - eating less calories while maintaining essential vitamins and minerals - can extend lifespan, and reduce cancer incidence and growth. But some types of cancer cell are more sensitive to the anti-growth effects of dietary restriction than others, Nada Kalaany and David Sabatini report. The effect hinges on the activity of the phosphatidylinositol-3-kinase (PI3K) pathway. If the pathway is active, dietary restriction has no effect on cancer cells. However, if the pathway is inactive, tumours are sensitive to dietary restriction.

Lingzhi mushroom - Wikipedia, the free encyclopedia - 0 views

  •  
    "Língzhī (traditional Chinese: 靈芝; simplified Chinese: 灵芝; Japanese: reishi; Korean: yeongji, hangul: 영지) is the name for one form of the mushroom Ganoderma lucidum, and its close relative Ganoderma tsugae. Ganoderma lucidum enjoys special veneration in Asia, where it has been used as a medicinal mushroom in traditional Chinese medicine for more than 4,000 years, making it one of the oldest mushrooms known to have been used in medicine. Lingzhi may possess anti-tumor, immunomodulatory and immunotherapeutic activities, supported by studies on polysaccharides, terpenes, and other bioactive compounds isolated from fruiting bodies and mycelia of this fungus (reviewed by R. R. Paterson[4] and Lindequist et al.[7]). It has also been found to inhibit platelet aggregation, and to lower blood pressure (via inhibition of angiotensin-converting enzyme[8]), cholesterol and blood sugar.[9] Laboratory studies have shown anti-neoplastic effects of fungal extracts or isolated compounds against some types of cancer. In an animal model, Ganoderma has been reported to prevent cancer metastasis,[10] with potency comparable to Lentinan from Shiitake mushrooms.[11] The mechanisms by which G. lucidum may affect cancer are unknown and they may target different stages of cancer development: inhibition of angiogenesis (formation of new, tumor-induced blood vessels, created to supply nutrients to the tumor) mediated by cytokines, cytoxicity, inhibiting migration of the cancer cells and metastasis, and inducing and enhancing apoptosis of tumor cells

Mango effective in preventing, stopping certain colon, breast cancer cells - 2 views

  •  
    "COLLEGE STATION - Mango. If you know little about this fruit, understand this: It's been found to prevent or stop certain colon and breast cancer cells in the lab. That's according to a new study by Texas AgriLife Research food scientists, who examined the five varieties most common in the U.S.: Kent, Francine, Ataulfo, Tommy/Atkins and Haden. Though the mango is an ancient fruit heavily consumed in many parts of the world, little has been known about its health aspects. The National Mango Board commissioned a variety of studies with several U.S. researchers to help determine its nutritional value. "If you look at what people currently perceive as a superfood, people think of high antioxidant capacity, and mango is not quite there," said Dr. Susanne Talcott, who with her husband, Dr. Steve Talcott, conducted the study on cancer cells. "In comparison with antioxidants in blueberry, acai and pomegranate, it's not even close." But the team checked mango against cancer cells anyway, and found it prevented or stopped cancer growth in certain breast and colon cell lines, Susanne Talcott noted. "It has about four to five times less antioxidant capacity than an average wine grape, and it still holds up fairly well in anticancer activity. If you look at it from the physiological and nutritional standpoint, taking everything together, it would be a high-ranking super food," she said. "It would be good to include mangoes as part of the regular diet." The Talcotts tested mango polyphenol extracts in vitro on colon, breast, lung, leukemia and prostate cancers. Polyphenols are natural substances in plants and are associated with a variety of compounds known to promote good health."

THE NEED FOR COMPLEMENTARY ALTERNATIVE CANCER THERAPIES - lefeurope.com - 0 views

  •  
    Mainstream medical treatment of cancer revolves around surgery, chemotherapy, and radiation therapy, used either alone or in combination (Isobe T et al 2005; Ostoros G et al 2005). Chemotherapy and radiation therapy cannot discriminate between cancer cells and healthy cells; thus, they damage both types of cells and cause serious and often debilitating side effects, frequently forcing patients to abandon treatment (Ettinger DS 2005; Giraud P et al 2004; Munden RF et al 2005). Therefore, it is not surprising that many cancer patients now opt to complement conventional treatments with alternative therapies that may not only temper the adverse side effects of conventional cancer therapy, but also improve its effectiveness via independent anti-cancer effects.

    Soy Food Intake and Breast Cancer Survival. Xiao Ou Shu et al. JAMA Vol. 302 No. 22, December 9, 2009; 302(22):2437-2443. Results During the median follow-up of 3.9 years (range, 0.5-6.2 years), 444 deaths and 534 recurrences or breast cancer-related deaths were documented in 5033 surgically treated breast cancer patients. Soy food intake, as measured by either soy protein or soy isoflavone intake, was inversely associated with mortality and recurrence. The hazard ratio associated with the highest quartile of soy protein intake was 0.71 (95% confidence interval [CI], 0.54-0.92) for total mortality and 0.68 (95% CI, 0.54-0.87) for recurrence compared with the lowest quartile of intake. The multivariate-adjusted 4-year mortality rates were 10.3% and 7.4%, and the 4-year recurrence rates were 11.2% and 8.0%, respectively, for women in the lowest and highest quartiles of soy protein intake. The inverse association was evident among women with either estrogen receptor-positive or -negative breast cancer and was present in both users and nonusers of tamoxifen. Conclusion Among women with breast cancer, soy food consumption was significantly associated with decreased risk of death and recurrence.

Apigenin flavonoid benefit and research studies : by Ray Sahelian, M.D. - 0 views

  •  
    "Apigenin is one of the flavonoids - more precisely one of the citrus bioflavonoids. Apigenin, just like most flavonoids, has antioxidant, anti-inflammatory, and anti-tumor properties. Perhaps apigenin can even block the formation of uric acid leading to beneficial effects in gout. Apigenin is found in high amounts in several herbs including parsley, thyme, and peppermint. It is is also found in a number of other herbs, including chamomile herb, Horsetail herb, lemon balm herb, perilla herb, vervain herb, and yarrow. Benefits of apigenin As with many flavonoids, apigenin has potential to reduce the risk of cancer since it has anti-tumor activity. Apigenin also could potentially be useful in allergy conditions since it can have anti-inflammatory properties.

    Berberine inhibits human tongue squamous carcinoma cancer tumor growth in a murine xenograft model. Ho YT, Yang JS, Lu CC, Chiang JH, Li TC, Lin JJ, Lai KC, Liao CL, Lin JG, Chung JG. Phytomedicine. 2009 Sep;16(9):887-90. Epub 2009 Mar 20. PMID: 19303753 Our primary studies showed that berberine induced apoptosis in human tongue cancer SCC-4 cells in vitro. But there is no report to show berberine inhibited SCC-4 cancer cells in vivo on a murine xenograft animal model. SCC-4 tumor cells were implanted into mice and groups of mice were treated with vehicle, berberine (10mg/kg of body weight) and doxorubicin (4mg/kg of body weight). The tested agents were injected once per four days intraperitoneally (i.p.), with treatment starting 4 weeks prior to cells inoculation. Treatment with 4mg/kg of doxorubicin or with 10mg/kg of berberine resulted in a reduction in tumor incidence. Tumor size in xenograft mice treated with 10mg/kg berberine was significantly smaller than that in the control group. Our findings indicated that berbeirne inhibits tumor growth in a xenograft animal model. Therefore, berberine may represent a tongue cancer preventive agent and can be used in clinic.

Study: Eating Soy Is Safe for Breast Cancer Survivors - TIME - 0 views

  •  
    "The common culprit is soy, a plant that contains chemicals with estrogen-like and anti-estrogenic properties - making it a nutritional minefield for breast cancer survivors. While Western diets are relatively low in soy - compared with the typical diet in Asia, where people eat soy daily - the percentage of Americans consuming soy at least once a week has increased from 15% in 1997 to 28% in 2003. In the meantime, studies on the effect of soy on breast cancer recurrence and mortality have been conflicting, with some showing that it can reduce risk, while others show an elevated rate of recurrent disease among high soy consumers. Now the largest study to date of soy's effect on breast cancer suggests that eating soy, even in large amounts, may not be harmful after all, and may even reduce recurrence and death from the disease. But while the findings are intriguing, not all doctors are ready to tout the benefits of tofu
