ALKBH5 and lung adenocarcinoma: Mechanistic analysis indicated that m6A demethylase ALKBH5 enhanced the proliferation and invasion of lung adenocarcinoma cells under intermittent hypoxia by down-regulating the level of m6A in FOXM1 mRNA and enhancing the translation efficiency of FOXM1 mRNA, resulting in the overexpression of FOXM1 protein [11].
