Androgen Receptor (AR)

Identifies cells responsible for the regulation of the growth of the prostate epithelial cells, positive in a subset of carcinomas, including those primary to the breast, salivary gland, and prostate. In untreated prostate carcinoma, AR positive cells are more likely to be responsive to hormonal therapy, while in hormone refractory prostate carcinoma, the presence of AR has a negative prognostic impact.
