DLX1 and posterior cortical atrophy: In order to screen out the genes associated with PCa, Venn analysis was conducted to analyse all the differentially expressed genes in GSE55945 and GSE45016 datasets as well as the first 500 significantly differentially expressed genes in the GSE38241 dataset (Figure 1D), the results of which showed that DLX1 was the only one of them that was simultaneously present and up‐regulated in all the three datasets.
