GENISTEIN INHIBITS $NF-_kB-DEPENDENT$ COX-2 INDUCTION IN HUMAN BREAST EPITHELIAL CELLS BY MODULATING THE ACTIVATION OF TATA-BINDING PROTEIN

Abstract

Genistein has been shown to possess chemopreventive potential. but its underlying molecular mechanisms are largely unclear. In the present study, we have investigated the effects of genistein on induction of cyclooxygenase-2 (COX-2) that plays an important role in the pathophysiology of carcinogenesis as well as in mediating inflammation. 12-Ο-Tetradecanoylphorbol-13-acetate(TPA) caused transient increases in cox-2 expression and prostaglandin E$_2$(PGE$_2$) production in MCF 10A cells, which was inhibited by genistein pretreatment.
