KCNQ5 and posterior cortical atrophy: After constructing miRNA-mRNA interaction networks (Figure 9), we identified six miRNAs: mmu-miR-6962-3p, mmu-miR-6989-3p, mmu-miR-6998-3p, mmu-miR-5627-5p, mmu-miR-15a-3p, and mmu-miR-6922-3p that have a potential interaction that regulate three DEGs KCNQ5, MUC1, and F3 in PCa (Figure 9).
