AR and posterior cortical atrophy: To identify the associated molecular pathways, we performed GREAT analysis of the SE regions and found a significant enrichment for R1881 response genes or ‘genes up‐regulated in PCa samples’ (Table S12), but interestingly also for ‘positive regulation of mesenchymal cell proliferation’, ‘positive regulation of stem cell proliferation’, and ‘prostate gland morphogenesis’, indicating that besides controlling AR hallmark genes, SEs fulfill other important functions (Fig. 4F, Table S12).
