XPO1 and posterior cortical atrophy: We previously published a list with proteins (n = 263) that were identified in EVs from normal prostate (PNT2C2 and RWPE‐1) and PCa (VCaP and PC346c) cell lines by using mass spectrometry.7 From this list, 10 proteins were identified as higher expressed in PCa‐derived EVs of which expression of 3 proteins (XPO1, FASN, and PDCD6IP) were further analyzed for EV and tissue expression.
