Phytoestrogens and Colon Cancer

Phytoestrogens as Nutritional Modulators in Colon Cancer Prevention

Phytoestrogens regulate vitamin D metabolism in the mouse colon: relevance for colon tumor prevention and therapy.

Soybean products are highly represented in the traditional Asian diet. Major components of soy proteins are phytoestrogens, such as isoflavones. They may be responsible for the extremely low incidence of prostate and mammary tumors and possibly also of colon cancer in countries such as China and Japan. Serum 1,25-dihydroxyvitamin D3 level is inversely related to incidence of some cancers. Level...

Phytoestrogens regulate transcription and translation of vitamin D receptor in colon cancer cells.

The present study assesses the effects of two isoflavones, genistein and glycitein, and equol - a product of intestinal bacterial metabolism of dietary isoflavones, on vitamin D receptor (VDR) expression in an intestinal HT29 cell line. Genistein and glycitein significantly upregulated the VDR transcription and translation in HT29 cells. The effect of equol was less pronounced. Treating HT29 ce...

Compare the effect of ginger extract and aspirin on COX-2 gene expression in colon cancer cell line HT-29

Background and aim: Colon cancer is the third most prevalent cancer in Iran. Prolonged colon inflammation is an important factor, in the development of colon cancer. Ginger has anti-inflammatory properties due to its content of [6]-gingerol and hence can play a role in the prevention of colon cancer. In this research the effects of ginger extract on reducing expression of the C...

Phytoestrogens: recent developments

Phytoestrogens are polyphenolic non-steroidal plant compounds with estrogen like activity exerted through estrogen receptors. These receptors are distributed in several tissues such as male and female reproductive systems, bones, cardiovascular and central nervous systems. These natural phenolic compounds include isoflavonoids, flavonoids, lignans and stilbenes. Isoflavonoids are the most studi...
