The data indicated that the AR mRNA expression in GOLM1‐overexpressing PCa cells and control cells was the same, but its target genes (KLK3, TMPRSS2 and NKX3‐1) mRNA expressions were obviously upregulated in the GOLM1‐overexpressing PCa cells in comparison to control cells (Figure 5A). This evidence concerns the gene KLK3 and posterior cortical atrophy.
