Through searching a TCGA database repository of Ualcan, we found a transcriptional profile of 52 normal prostate tissues and 491 PCa specimens by microarrays, which revealed that the expression of hepaCAM in the PCa tissues was markedly lower than in the normal tissues, while the mRNA level of EZH2 showed the opposite pattern (Fig. 4b). This evidence concerns the gene HEPACAM and posterior cortical atrophy.
