Fig. 3: The roles of m6A in regulating KCTD21-AS1 activity.

a meRIP analysis of m6A-modified KCTD21-AS1 in A549 cells. b, c METTL14 overexpression increased, but siRNA-METTL14 inhibited KCTD21-AS1 levels in A549 cells. d, e Effect of METTL14 overexpression and siRNA-METTL14 on KCTD21-AS1 levels in H1975 cells. f, g CCK8 assay showed METTL14 overexpression promoted, whereas siRNA-METTL14 inhibited A549 cell proliferation. h, i METTL14 overexpression promoted, whereas siRNA-METTL14 inhibited H1975 cell growth. j Blocking KCTD21-AS1 attenuated the roles of METTL14 in increasing KCTD21-AS1 expression. k Blocking KCTD21-AS1 accelerated the roles of siRNA-METTL14 in decreasing KCTD21-AS1 expression. Data was presented as meanā±āSD for triplicate experiments. *pā<ā0.05; **pā<ā0.01; Studentās t-test or ANOVA.
