Cancer cells have a complex interplay among different pathways, some components commonly associated with carcinogenesis are Mitogen-Activated Protein Kinase (MAPK) or Extracellular-signal-Regulated Kinase (ERK), Wnt/β-catenin, Phosphatidylinositol 3-kinase (PI3K)/AKT, mammalian Target of Rapamycin (mTOR), and Nuclear factor-E2 p45-related factor (Nrf2). Here, MTOR is linked to cancer.
