The majority of KEGG mTOR signaling components (25 out of 38 genes) were predicted to be targeted by AA-depleted miRNAs (miR-34a-5p, miR-99b-5p, miR-125b-2-3p and miR-378a-5p, which were downregulated in AA PCa vs. EA PCa), and only five genes were predicted to be targeted by AA-enriched miRNAs (miR-96-5p and miR-130b-3p, which were upregulated in AA PCa vs. EA PCa). Here, MTOR is linked to posterior cortical atrophy.
