Yao et al.80verified that METTL14 enhances phosphatase and tensin homologue (PTEN) m6A modification by interconnecting the m6A characteristic sequence GGACT with PTEN mRNA, improving RNA stability of PTEN and playing a role in cancer inhibition in stomach adenocarcinoma (STAD). This evidence concerns the gene METTL14 and gastric adenocarcinoma.
