To further verify the role of the P53/miR-133a-3p axis in NPC, the miR-133a-3p inhibitor was transfected into P53-overexpressing HONE1 and SUNE1 cells and the expression of various proteins involved in the EGFR/PI3K/AKT/c-Myc signaling pathway was examined. Here, TP53 is linked to nasopharyngeal carcinoma.
