Target Background

The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the glycolytic pathway to the tricarboxylic cycle.

  12. In the presence of PPARbeta/delta, Vpr induced a 3.3-fold increase in PPAR response element-driven transcriptional activity, a 1.9-fold increase in PDK4 protein expression, and a 1.6-fold increase in the phosphorylated pyruvate dehydrogenase subunit E1alpha. PMID: 23842279
