METTL3 enhanced the stability of DLGAP1-AS2 in m6A-dependent manner. (a) GEPIA dataset revealed the positive correlation within METTL3 and DLGAP1-AS2 in LUSC (Lung squamous cell carcinoma, http://gepia.cancer-pku.cn/). (b) The METTL3 protein was detected in NSCLC cells upon METTL3 overexpression transfection. (c, d) The m6A modification levels were detected using m6A RNA Methylation Quantification Kit (Colorimetric). (e, f) RNA stability analysis revealed the RNA remaining of DLGAP1-AS2 in H1299 cells and A549 cells treated by Act D (actinomycin D, 1 μg/m). LncRNA DLGAP1-AS2 was determined by qRT-PCR assay. *p < 0.05.
