AR
Use
Androgen receptor (AR) is responsible for the regulation of the growth of the prostate epithelial cells. In untreated prostate carcinoma, AR positive cells are more likely to be responsive to hormonal therapy. In patients with hormone refractory prostate carcinoma, the presence of AR has a negative prognostic impact. It is also commonly expressed in salivary duct carcinoma.
