The androgen receptor (AR) belongs to the superfamily of nuclear receptors that employ complex genetic mechanisms to guide the development and physiological functions of different target tissues. Upon interaction with its cognate hormone, AR activates or represses gene transcription through associat

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 androgen receptor (AR), a nuclear receptor transcription factor. Historically, the gene expression program mediated by the AR has been poorly understood. However, recent gene expression profiling and more traditional singleโgene characterization studies have revealed many androgenโregulated genes that are important mediators of androgen action in both normal and malignant prostate tissue. This review will focus on the androgenโregulated gene expression program, and examine how recently identified androgenโregulated genes are likely to contribute to the development and progression of prostate cancer. We will also summarize several recent studies that have attempted to unravel how these genes are deregulated in androgen depletion independent prostate cancer. J. Cell.
