Another small-molecule FTO inhibitor, Dac51, has also been confirmed to serve as an essential reprogramming RNA epitranscriptome factor to prevent tumor cells from evading CD8+T cells surveillance mediated by glycolytic metabolism, which is induced by transcription factors c-Jun, JunB, and C/EBPβ mediated by FTO in an m6A dependent tone 216. This evidence concerns the gene CD8A and neoplasm.
