MTOR and neoplasm: Significant progress has been made in understanding the critical role of m6A regulatory proteins involved in many canonical pathways, such as C-MYC, Wnt/β-catenin, PI3K/AKT/mTOR, p53, and epithelial-mesenchymal transition (EMT), which may be potential therapeutic signaling pathways due to their key role in tumor occurrence, migration, proliferation, apoptosis, metastasis, drug resistance, and treatment response.
