In conclusion, our results provide evidence in support of a model in which the high expression of PCBP2 and its binding to ARHGDIA may induce a local change in RNA structure that favors association with miR-151-5p and miR-16, thus leading to suppression of ARHGDIA expression, and the low expression or loss of ARHGDIA induces EMT and promotes glioma migration and invasion (Figure 6G). Here, PCBP2 is linked to glioma.
