Chemopreventive effects of soy protein and purified soy isoflavones on DMBA-induced mammary tumors in female Sprague-Dawley rats
(2001)There are conflicting reports on the effect of soy and its components on mammary carcinogenesis in adult female rats, mainly because of different rodent models that are used in chemoprevention studies. The present study ...

The effect of the phytoestrogens genistein, daidzein, and equol on the growth of tamoxifen-resistant T47D/PKCα
(2007)Soy supplements are often consumed by women for alleviating menopausal symptoms or for the perceived protective effects against breast cancer. More concerning is the concurrent consumption of soy isoflavones with tamoxifen ...

Flavonoids as DNA topoisomerase antagonists and poisons: Structure-activity relationships
(1995)Selected flavonoids were tested for their ability to inhibit the catalytic activity of DNA topoisomerase (topo) I and II. Myricetin, quercetin, fisetin, and morin were found to inhibit both enzymes, while phloretin, ...

Genistein inactivates bcl-2, delays the G2/M phase of the cell cycle, and induces apoptosis of human breast adenocarcinoma MCF-7 cells
(1998)The aim of this study was to identify the molecular mechanism of action of the isoflavone, genistein. Genistein at 0.15 mM caused MCF-7 apoptotic cell death, which was accompanied by cell cycle delay in the G2/M phase. ...

Induction of human adenocarcinoma cell differentiation by the phytoestrogen genistein is independent of its antiestrogenic function
(1997)The objective of the present study was to determine if genistein can induce human breast adenocarcinoma cell maturation. To gain understanding on its mechanism of action, we used estrogen receptor-positive (ER+) MCF-7, and ...

Inhibition of N-methyl-N-nitrosourea-induced mammary tumors in rats by the soybean isoflavones
(1996)Soy-based diets, rich in the isoflavones genistein and daidzein, are thought to protect against breast and prostate cancer. Soy-based diets, rich in the isoflavones genistein and daidzein, are thought to protect against ...

Phenoxodiol (2H-1-benzopyran-7-0,1,3-(4-hydroxyphenyl)), a novel isoflavone derivative, inhibits DNA topoisomerase II by stabilizing the cleavable complex
(2002)Cancer therapeutic drugs that inhibit DNA topoisomerase (topo) II by stabilizing the cleavable complex are collectively known as topo II poisons. Phenoxodiol is a synthetic derivative of the plant isoflavone daidzein and ...
