Prostate cancer is considered to be one of the most hormone-dependent human malignancies. As a key mediator of hormonal response, the androgen receptor (AR) is believed to have an important role in the progression of prostate cancer. Mutations in the coding region of the AR gene have been found in b

Abstract
The importance of androgens and androgen receptors (AR) in primary prostate cancer is well established. Metastatic disease is usually treated with some form of androgen ablation, which is effective for a limited amount of time. The role of AR in prostate cancers that recur despite androgen ablation therapy is less certain. Most of these tumors express prostate specific antigen (PSA), an androgenโregulated gene; moreover, AR is generally highly expressed in recurrent prostate cancer. We propose that AR continues to play a role in many of these tumors and that it is not only the levels of AR, ligands, and coโregulators, but also the changes in cell signaling that induce AR action in recurrent prostate cancer. These pathways are, therefore, potential therapeutic targets. J. Cell. Biochem. 99: 362โ372, 2006. ยฉ 2006 WileyโLiss, Inc.

## Abstract Androgens are critical regulators of prostate differentiation and function, as well as prostate cancer growth and survival. Therefore, androgen ablation is the preferred systemic treatment for disseminated prostate cancer. Androgen action is exerted in target tissues via binding the and
