Function
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.

Mechanism Description LDHB and PDHA1 were downregulated in GEO-CR tumor xenografts, similarly to the corresponding deregulations observed in the derived cell lines. Upregulation of G6PDH and transketolase (TkT) was also actually maintained in tumor xenografts. Indeed, PPP2CA expression in xenografted samples was similarly evaluated, demonstrating that protein downregulation in vivo was even more pronounced than that measured in GEO-CR cells.
