PPIB and posterior cortical atrophy: A comparison of CypA and CypB protein levels revealed that (1) CypA is 2.8-fold higher in PCa/CRPC/NEPC compared to RWPE-1 non-cancer cells, and (2) CypB is 2-fold lower in PC3, H660, and LASCPC compared to LNCaP, 22Rv1, and RWPE-1 (Supplementary Materials, Figure S11).
