..., the mitochondrial enzyme that converts pyruvate into acetyl-CoA. In combination with the hypoxia-induced expression of LDHA (lactate dehydrogenase A), which converts pyruvate into lactate, PDK1 reduces the delivery of acetyl-CoA to the tricarboxylic acid cycle, thus reducing the levels of NADH and FADH 2 delivered...

...) resulted in a surprising decrease in the contribution from glycogen and an increase in that from PEP to glucose production. A change in the lactate/pyruvate ratio from 10:1 to 1:10 also stimulated flux through the tricarboxylic acid cycle (2-fold), while leaving oxygen consumption and overall glucose...
