METTL14-mediated Lnc-LSG1 m6A modification inhibits clear cell renal cell carcinoma metastasis via regulating ESRP2 ubiquitination.

ABSTRACT: Clear cell renal cell carcinoma (ccRCC) is the most lethal urological cancer and is characterized by a high rate of metastasis and relapse. N6-Methyladenosine (m⁶A) is implicated in various stages of cancer development. However, a thorough understanding of m⁶A-modified lncRNAs in ccRCC is lacking. The results showed that METTL14 had decreased expression in ccRCC tissues. In addition, the expression of METTL14 was negatively correlated to the prognosis, stage, and ccRCC tumor grade. The silencing of METTL14 was shown to significantly increase metastasis in vitro and in vivo. High-throughput methylated RNA immunoprecipitation sequencing (MeRIP-seq) showed that the m⁶A levels of Lnc-LSG1 could be regulated by METTL14. Lnc-LSG1 can directly bind t
