AKT1 and neoplasm: Mechanistically, RNA-seq, MeRIP-seq and RIP-seq analysis, and molecular biology experiments demonstrated that YTHDF2 accelerated the degradation of DNA damage-inducible transcript 4 or regulated in DNA damage and development 1 (DDIT4, or REDD1) mRNA in an m6A-dependent manner, which in turn activated the AKT/mTOR signaling pathway and induced activation of epithelial-mesenchymal transition (EMT), thereby promoting ATC tumor progression.
