Revisiting Androgen Receptor Signaling in Breast Cancer.

ABSTRACT: Aberrant estrogen receptor (ER) signaling is central to the pathogenesis of many breast cancers. Like ER, the androgen receptor (AR) is a steroid nuclear receptor that is frequently expressed in breast cancer and has long been considered an attractive therapeutic target. Although androgens were historically employed in the treatment of breast cancer, this strategy has largely fallen out of favor with the advent of modern anti--estrogens, due to virilizing effects from androgens, as well as concerns that androgens could be converted to estrogens to fuel tumor growth. Recent molecular advances, however, including the development of selective androgen receptor modulators, have renewed interest in targeting the AR. Yet androgen signaling in breast cancer remains incompletely understood, and pr
