In agreement, analysis of STAT3 expression in PCa tumors from the TCGA‐PRAD dataset revealed significantly higher levels of STAT3 mRNA in ETV1‐positive tumors compared to ETS‐negative tumors, with ERG‐positive tumors showing a tendency for increased STAT3 expression (Fig. 2K). The gene discussed is STAT3; the disease is posterior cortical atrophy.
