17Beta-estradiol induces ERbeta up-regulation via p38/MAPK activation in colon cancer cells.

Abstract

Estrogen receptors (ERalpha and ERbeta) mediate opposite functions on cancer growth induced by 17beta-estradiol (E2). E2 binding to ERalpha induces a cancer promoting response, whereas E2 binding to ERbeta exerts a protective action against cancer growth. Moreover, E2 can diversely modulate the ERalpha and ERbeta levels intensifying or decreasing their… (More)
