What is Genistein?

Genistein is a soy-derived isoflavone and phytoestrogen with antineoplastic activity. Genistein binds to and inhibits protein-tyrosine kinase, thereby disrupting signal transduction and inducing cell differentiation. This agent also inhibits topoisomerase-II, leading to DNA fragmentation and apoptosis, and induces G2/M cell cycle arrest. Genistein exhibits antioxidant, antiangiogenic, and immunosuppressive activities.

Usage And Synthesis 

Estrogenic effect

The estrogenic activity of genistein has been confirmed in many studies. Of all the isoflavones, genistein has the strongest estrogenic activity. The estrogenic effect of genistein may explain its protective action against osteoporosis and its possible effect on body weight reductions. Genistein is also used to ease menopause symptoms, such as hot flushes.
Genistein is a strong antioxidant. Genistein removes damaging free radicals and reduces lipid peroxidation. Genistein increases the activity of other antioxidant enzymes such as glutathione peroxidase, superoxide dismutase and glutathione reductase. Studies have shown that genistein can also influence the growth of cells which are not hormone-dependent.
Genistein seems to reduce the risk for some hormone related cancers, principally breast cancer and prostate cancer. Epidemiological studies show that consumption of isoflavones may protect against breast and prostate cancer. High dietary intake of soy products China and Japan are linked with low incidence of these cancers. There are lots of theories to explain the anti-cancer action of genistein: inhibition of angiogenesis, inhibition of tyrosine kinases, antioxidant property, and anti-estrogen action (it is known that estrogen increases risk for certain cancers). Genistein binds with estrogen receptors, preventing the estrogen from binding and initiating cancer growth.
Heart health
Many in-vitro tests have demonstrated that genistein inhibits cellular cholesterol synthesis and cholesterol esterification. Genistein also reduces fatty acid oxidation and exerts lipid lowering effect. Only oxidized LDL cholesterol is absorbed by the arterial cells and prevention of this oxidation will reduce the risk for arteriosclerosis. Gensistein prevents the formation of hearth attacks and strokes by acting as anticlotting agent.
