Consistent with RT-qPCR results from patient samples, miR-34a-5p and miR-99b-5p were downregulated in AA PCa vs. EA PCa cell lines (Figure 3A), while their predicted targets PIK3CB, MTOR, HIF1A and IGFBP2 were upregulated in AA PCa vs. EA PCa cells (Figure 3B). This evidence concerns the gene PIK3CB and posterior cortical atrophy.
