ICA1 and posterior cortical atrophy: To investigate the potential role of BAP1 in PCa progression, BAP1 was silenced by shRNAs targeting the 3′‐terminal untranslated region (UTR) of BAP1 mRNA in DU145 and P69 cells (Fig. S2A), or ectopically expressed in M12 cells by the lentiviral expressing system.
