We explored the expression of GRPR, PSMA, and NTR1 in PCa cell lines and found low expression of PSMA but high expressions of GRPR and NTR1 in PC-3 cells; however, there were increased expressions of GRPR and NTR1 in the DU145 and LNCaP cells. The gene discussed is FOLH1; the disease is posterior cortical atrophy.
