We further investigated the correlation between AR signaling and miR-203 levels and observed that increased levels of miR-203 expression were strongly associated with the induced expression of two different AR pathway gene signatures [31, 32] according to a gene set enrichment analysis (GSEA) of the Taylor PCa dataset (Figure 1E, 1F, and Supplementary Figure S1C, S1D). This evidence concerns the gene AR and posterior cortical atrophy.
