(WASHINGTON, February 3, 2009) - Green tea products have become regarded as a valuable health supplement, as studies have shown evidence of its benefit against a variety of diseases, including cancer. However, a new study suggests that some components of green tea may counteract the anticancer effects of one cancer therapy, bortezomib (Velcade®), and may be contraindicated for patients taking this medicine to ensure its maximum therapeutic benefit. This study is being prepublished online today in Blood, the official journal of the American Society of Hematology.
A chemical found in green tea appears to slow the progression of prostate cancer, a study has suggested.
Green tea has been linked to a positive effect on a wide range of conditions, including heart disease, cancer and Alzheimer's disease.
NEW YORK (Reuters Health) - Women who get plenty of mushrooms and green tea in their diets may have a lower risk of developing breast cancer, new study findings suggest.\n\nThe study, of more than 2,000 Chinese women, found that the more fresh and dried mushrooms the women ate, the lower was their breast cancer risk.
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
Simultaneously Blocking Glycolysis and Fat Metabolism
Can the use of DCA and a fatty acid metabolism blocker together force more cancer cells into using aerobic metabolism?
Tim McGough used green tea extract, which contains EGCG, in his fantastic response.
DCA works by reactivating mitochondria and shifts metabolism from glycolysis to glucose oxidation. Hopefully the cancer cell will then undergo apoptosis. However, cancer cells have an alternate energy source: fat metabolism. This page explores to possibility of blocking fat metabolism to help force the cell into apoptosis.
Oral squamous cell carcinoma is a cancer that does not respond well to DCA. This study, Head and Neck Cancer Cell Lines Are Resistant to Mitochondrial-Depolarization-Induced Apoptosis states:
"Results: ΔΨm in head and neck cell lines started to show slight loss of ΔΨm, while HL-60 showed significant loss of ΔΨm after 30 min of treatment. All cell lines demonstrated complete mitochondrial depolarization within 24 h, however, only the control cell line HL-60 underwent apoptosis. In addition, HNSCC cell lines did not demonstrate cytoplasmic cytochrome c release despite significant mitochondrial membrane depolarization, while HL-60 cell initiated apoptosis and cytochcrome c release after 24 h of treatment. Conclusions: Head and neck cancer cell lines exhibit defects in mitochondrial-membrane-depolarization-induced apoptosis as well as impaired release of cytochrome c despite significant mitochondrial membrane depolarization. Proximal defects in the mitochondrial apoptosis pathway are a feature of HNSCC.(head and neck squamous cell carcinoma)"
Note that although the cell lines were depolarized, apoptosis did not occur. So I checked to see if fatty acid metabolism is used by squamous cell carcinoma.
"Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.
Blueberry Punch is an Australian product but is available for sale on the internet at £16 a bottle.\n\nIt also includes a host of other natural ingredients thought to boost health, including green tea, olive leaves, the herb tarragon and the spices turmeric and ginger.\n\nIt is thought the ingredients act together to cut inflammation and block a cancer gene.\n\nDr Jas Singh, who conducted the research on mice at Sydney University, said: "We have undertaken efficacy studies on individual components of Blueberry Punch in the same laboratory setting and found these effective in suppressing cell growth in culture.\n\n"We reasoned that synergistic or additive effects are likely to be achieved when they are combined."\n\nThe researchers looked at the effect of Blueberry Punch on both cancer cell cultures in the laboratory and genetically engineered mice with human prostate tumours. After only two weeks of having the syrupy solution added to their drinking water, their tumours had shrunk by
