WebSep 5, 2024 · As a consequence of heightened glycolysis, lactate levels can be up to 40 mM in tumors; otherwise, the physiological concentration of lactate is between 1.8 mM and 2 mM in normal tissue [ 4]. Hence, lactic acidosis generally exists in solid tumor microenvironments. WebDec 4, 2015 · Lactate first stabilizes hypoxia-inducible factor-2α (HIF-2α), and HIF-2α then transactivates c-Myc in a pathway that mimics a response to hypoxia. Consequently, lactate-induced c-Myc activation triggers the expression of glutamine transporter ASCT2 and of glutaminase 1 (GLS1), resulting in improved glutamine uptake and catabolism.
