Mechanism of Selenium Chemoprevention and Therapy in Prostate Cancer
Abstract
Prevention trials demonstrated that selenium is a promising chemopreventive agent for prostate cancer. Selenium inhibited human prostate cancer cell growth blocked cell cycle progression and induced apoptotic cell death. We have demonstrated a novel mechanism of selenium anticancer action in which selenium markedly reduces androgen receptor (AR) expression and AR-mediated gene expression including prostate-specific antigen (PSA) in human prostate cancer cells in vitro and in vivo. Based on our novel finding that selenium disrupts AR signaling by reducing AR expression it is conceivable that selenium (reducing AR expression) might improve the efficacy of androgen deprivation therapy. In this application we will test the effects of selenium on prostate cancer therapy.
