Cover Story: Commonly in lung cancer, EGFR mutations increase PI3K activity through PKB/AKT activation; in addition, these kinases simultaneously participate in cell metabolism through stimulation of HIF1a expression and mTOR activation. This effect promotes translocation and increased expression of GLUTs and HKs, increasing glycolytic potential. Metformin treatment blocks mTOR activity through AMPK activation, increasing the function of TSC2/RHEB, which inhibits protein synthesis promoted by mTOR and its effectors. In addition, metformin modulates protein and enzymes that regulate key metabolic pathways, such as glycolysis and lipid metabolism, leading to the down-regulation of cell proliferation, migration and protein synthesis.
