To determine whether miR-133a-3p participated in the VPS33B-modulated EGFR/PI3K/AKT/c-Myc/p53 signaling pathway and the formation of a loop mechanism in NPC cells, we examined the expression of miR-133a-3p in VPS33B-overexpressing cells by RT-qPCR analysis. Here, AKT1 is linked to nasopharyngeal carcinoma.
