To study the expression of SOD2 in prostate cells, we performed western blot analysis, using known normal transformed prostate epithelial (RWPE-1) and PCa (LNCaP, 22Rv1, DU 145, PC-3, ARCaP E, ARCaP M, C4-2, and MDA-PCa-2b) cell lines. This evidence concerns the gene SOD2 and posterior cortical atrophy.
