Regulation of glycolysis and gluconeogenesis enzymes by epigenetic modifications. Epigenetic regulatory enzymes, lncRNA, and circRNA regulate the epigenetic regulation of the key proteins, GLUT1, HK2, PKM, ENO2, LDHA, IDH, and the key enzymes FBP and PCK in the process of gluconeogenesis. GLUT1, glucose transporter type 1; HK2, hexokinase 2; PKM, pyruvate kinase M1/2; ENO2, enolase 2; LDHA, lactate dehydrogenase A; IDH, isocitrate dehydrogenase (NADP (+)); FBP, fructose-bisphosphatase; PCK, phosphoenolpyruvate carboxykinase.
