Through co-transfection of PCa cell lines with SNAI1 and miR-30e-5p-inhibitors, miR-30e-5p-mimics, or empty vectors, cell proliferation and migration were found to be enhanced, while cell apoptosis was retarded in the OE-SNAI1 + miR-30e-5p inhibitor group. Here, SNAI1 is linked to posterior cortical atrophy.
