EGFR and posterior cortical atrophy: In agreement with this, data obtained for the Prostate Adenocarcinoma tumor samples from The Cancer Genome Atlas (TCGA‐PRAD) showed a significant increase in EGFR expression and a tendency for increased p‐EGFR expression in ETV1‐positive PCa (Fig. 1H,I), supporting differential EGFR regulation by ETS proteins and a positive association between EGFR and ETV1 expression in human PCas.
