Abstract
Abstract N 6 ‐methyladenosine (m 6 A) and long noncoding RNAs (lncRNAs) are both crucial regulators in non‐small‐cell lung cancer (NSCLC) tumorigenesis. However, the pathological roles of m 6 A and lncRNAs in NSCLC progression are still limited and undefined. Here, lncRNA ABHD11‐AS1 was upregulated in NSCLC tissue specimens and cells and the ectopic overexpression was closely correlated with unfavorable prognosis of NSCLC patients. Functionally, ABHD11‐AS1 promoted the proliferation and Warburg effect of NSCLC. Mechanistically, m 6 A profile was analyzed by methylated RNA immunoprecipitation sequencing (MeRIP‐Seq). MeRIP‐Seq presented that there was m 6 A modification site in ABHD11‐AS1. m 6 A methyltransferase‐like 3 (METTL3) installed the m 6 A modification and enhanced ABHD11‐AS1 transcript stability to increase its expression. In conclusion, our findings highlight the function and mechanism of METTL3‐induced ABHD11‐AS1 in NSCLC and inspire the understanding of m 6 A and lncRNA in cancer biology.
