miR-3188 expression was positively correlated with FOXO1 expression (Fig. 7e; Spearman's correlation coefficient, P=0.0326), but negatively associated with mTOR (Fig. 7e; Spearman's correlation coefficient, P=0.0288) and c-JUN expression (Fig. 7e; Spearman's correlation coefficient, P=0.0006) in the same NPC specimens. Here, FOXO1 is linked to nasopharyngeal carcinoma.
