LIN28A and prostate disorder: To confirm this point, soft agar colony‐forming assays were performed with T47D‐shLIN28A re‐expressing HA‐LIN28A‐WT/‐K15R, DU145 stably expressing HA‐LIN28A‐WT/‐K15R cell lines and BPH1 (human prostate hyperplasia cells) stably expressing HA‐LIN28A‐WT/‐K15R cell lines (Fig. S7A).
