METTL3 and lung cancer: Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a LncRNA highly correlate to the occurrence and development of lung cancer, has been also indicated that its level was increased due to a higher level of m6A modification mediated by METTL3 and meanwhile, METTL3/YTHDF3 complex is able to elevate the stability of MALAT1 in non-small cell lung carcinoma (NSCLC) cells [22].
