CDH1 and posterior cortical atrophy: The differential mRNA expression of EMT-associated transcripts showed a statistically significant difference only in the expression of CDH1 (E-cadherin; p-value < 0.0004) in EBV-positive and EBV-negative tissues (Fig. 3A ; Figure S1), where the expression of CDH1 was found to be 1.2-fold lower in EBV-positive PCa tissues compared to EBV-negative PCa tissues (Fig. 3A; Table S1).
