The 110 kDa molecular weight protein known as theandrogen receptor (AR) is recognized by the androgenreceptor antibody. It responds to the receptor’s entirelength and A shape. It is quite selective and doesn’t interactwith glucocorticoid, progesterone, or estrogen receptors.According to reports, there is an inverse relationshipbetween the expression of AR and poorly differentiatedtumors; well-differentiated tumors have high levels of ARexpression, while poorly differentiated tumors exhibit littleto no androgen receptor expression. High expression of theandrogen receptor in prostate cancer biopsies may aid inidentifying patients who would benefit from anti-androgentherapy because androgen has been suggested as ameasure of hormone responsiveness in prostate cancer.Dermatopathology, Paget’s disease, and breast cancer arefurther uses for the androgen receptor.
