Nutraceuticals and Cancer by Fazlul H. Sarkar download in ePub, pdf, iPad

Enzymes are essential biochemical units that play a necessary role in virtually all the functions of every organ system in the body. Some flavonoids were first shown to be apoptotic in human lymphoid leukemic cells and human carcinoma cells. The use of garlic as anticancer agent has long been established.

Caffeic acid phenethyl ester, an active phenolic component extracted from honey bee propolis, blocks tumorigenesis in a two stage model of mouse skin cancer. Silibinin can suppress the proliferation of these cells, while at the same time increasing the rate at which the die by apoptosis. The mechanisms responsible for these effects have been studied most intensively in human prostate cancer cells. Prostate cancer is the most common cancer affecting men in the U.

Mushroom extracts are known to have immunomodulation and antitumor effects. Their ability to reduce cancer incidence in these studies is likely related to apoptosis. Diallylsulfide and diallyldisulfide induce apoptosis in non-small cell lung cancer cells and in prostate cancer and breast cancer cells. These bacteria can stimulate the immune system because of the polysaccharides in their cell walls.

Caffeine Adenosine is another immunosuppressive agent produced in many tumors, especially in poorly oxygenated tumor regions. Half of cancer deaths are accounted for by cancers for which there are screenings. One of the nasty side effects of chemotherapy is that it can severely depress the immune system. Pancreatic Enzymes There is a key difference between normal cells and tumor cells.

It is an

However, there is also evidence that cimetidine has immuno-stimulant activity for natural killer cells and cytotoxic T-cells. Silibinin can suppress the proliferation of these cells and reduce their ability to migrate, invade tissues and roll themselves into tubes, which is how new blood vessels are formed. Indeed, defect in apoptosis mechanism is recognized as an important cause of carcinogenesis. In endothelial cells, it produces proteinoids required for vascular tube formation during the angiogenic process. They are catalysts, substances that accelerate and precipitate the biochemical reactions that control the basic processes of life in each living organism.

It is an essential component of the energy production process within our cells. Among them, tea polyphenols, quercetin, and genistein have been widely studied for their potential chemopreventive applications. Salicylyc acid, like aspirin, can inhibit cyclooxygenase enzymes, but its activity in this regard is very weak and reversible. Curcumin induces apoptosis in colon carcinoma cells, leukemic cells, prostate cancer cells, melanoma cells, and breast cancer cells. One can use it as a chemical template for combinatorial synthesis.

Among them tea polyphenols
