Several studies have reported that 3′ UTR of FOXO3a is targeted by oncogenic microRNAs, including miR-10b [223], miR-27a [224], miR-93 [225], miR-155 [226], and miR-184 [218] that their expression is upregulated in glioma cell lines (Table 5). This evidence concerns the gene FOXO3 and central nervous system cancer.
