While inhibiting the Akt-mTOR pathway [57,58,59] and thus promoting autophagy, quercetin can also downregulate the expression of glucose transporter protein 1 (GLUT1) and the expression of pyruvate kinase M2 (PKM2) and lactate dehydrogenase A (LDHA), which are key enzymes of glycolysis, and inhibit tumor cell glycolysis and cell migration [58]. This evidence concerns the gene LDHA and neoplasm.
