CDC20 and posterior cortical atrophy: In addition to EMT genes, the expression of four other genes, namely AR, CHEK-2, CDKN-1B, and CDC-20, implicated in the oncogenesis of PCa, was found to be significantly different (p < 0.05) in EBV-positive compared to EBV-negative PCa tissues (Fig. 3A; Table S1).
