ATG5 is a downstream target of METTL3 for autophagy regulation. (A) m6A modification level of ATG5 in TCam-2 cells upregulating or downregulating METTL3. (B,C) mRNA and protein expression of ATG5 in TCam-2 cells transfected with METTL3 plasmid or si-METTL3. GAPDH served as the internal control. (D) Immunofluorescence image of LC3-II (red) in TCam-2 cells. TCam-2 cells were treated with METTL3 transfection or si-ATG5. (E) Western blot analysis of LC3II/GAPDH ratio and Beclin1. GAPDH served as the internal control. (F) Cell viability of METTL3 overexpressing TCam-2 cells treated with or without si-ATG5 after incubated with CDDP (IC25) for 72 h. All data are shown as the means ± S.D. *, P<0.05; **, P<0.01; ***, P<0.001. m6A, N6-methyladenosine; CDDP, cis-diamminedichloroplatinum II; S.D., standard deviation.
