PDH, mitochondrial pyruvate dehydrogenase (PDH): Click to Expand ⟱

Source:

Type:

-An enzyme complex that plays a crucial role in cellular metabolism, particularly in the conversion of pyruvate to acetyl-CoA, which is then used to produce energy in the form of ATP. -Key enzyme in cellular metabolism that catalyzes the conversion of pyruvate (produced during glycolysis) into acetyl-CoA, which then enters the tricarboxylic acid (TCA) cycle in the mitochondria.
The phosphorylation state of PDH (p-PDH) broadly exists in the cancer cells.
Some cancer cells have been found to inhibit PDH activity, which can lead to increased lactate production and a shift towards glycolysis, even in the presence of oxygen. This is known as the Warburg effect.
-In cancer cells, PDH has been shown to be inhibited.
PDH expression is regulated by various transcription factors, including HIF-1α, c-Myc, and p53.
