For a systematic study, we chose a PSMA‐positive, androgen‐dependent prostate cancer cell line (LNCaP) and a PSMA‐null, androgen‐independent cell line (PC3).[28] The cells were cultured under the same conditions (i.e., culture media supplemented with 10%, v/v FBS and 1%, v/v penicillin‐streptomycin). Here, FOLH1 is linked to prostate carcinoma.
