TOMM20 and posterior cortical atrophy: TOMM20 is positively correlated with AR at the mRNA levels in 548 PCa cases from TCGA database (Person r = 0.5069, Fig. 1B), and at the protein levels in non-malignant prostate epthelial cell line RWPE-1 and PCa cell lines as shown in Fig. 1C. By immunohistochemical (IHC) analysis, we further validated the correlation of AR and TOMM20 protein levels in 6 BPH and 39 PCa cases.
