MEN1 and posterior cortical atrophy: Interestingly, MEN1-KD also led to a decreased number of colonies formed in PC3 cells re-expressing AR (PC3-AR), to a lesser extent than in AR-dependent cells but significantly greater than AR-independent PCa cells (Fig. S1a-b), consistent with the previously observed reduced cell proliferation in MEN1-KD PC3-AR cells [23].
