METTL3 promotes resistance to cisplatin by enhancing autophagy. (A) LC3-II/GAPDH ratio and Beclin1 levels were determined by western blot analysis after overexpression or knockdown of METTL3 in TCam-2 cells. GAPDH served as the internal control. (B) Immunofluorescence of LC3-II was performed in TCam-2 cell line with different METTL3 expression. The red signal represents the LC3-II levels. (magnification, 400×). (C) Cell viability after 72 h treatment with IC25 concentration of CDDP. The METTL3-overexpressing TCam-2 cell were treated with or without autophagy inhibitor 3-MA. The data are shown as the means ± S.D. *, P<0.05; **, P<0.01; ***, P<0.001. 3-MA, 3-methyladenine; S.D., standard deviation; CDDP, cis-diamminedichloroplatinum II.
