The prostate cancer cell lines that were chosen represent well-characterized tumor states (i.e., androgen dependent (LNCaP), androgen sensitive (LNCaP/C4-2) and castration resistant (22Rv1)), and also include examination of mutated forms of AR (i.e., LNCaP) and AR splice variants (i.e., 22Rv1). Here, AR is linked to prostate carcinoma.
