The PTGES-AKT-HIF-1 axis constitutes a core pathway for inflammation-induced glycolysis: pro-inflammatory factors such as IL-4 and IL-13 upregulate PTGES, which catalyzes the conversion of PGH2 to PGE2 to activate the PI3K-AKT pathway downstream of G protein-coupled receptors ( Abnormalities in the PPP are primarily manifested as oxidative stress-induced compensatory activation
