Interaction Information:
| Comment | Under hypoxic conditions, which are frequently encountered in the tumor environment, pyruvate enters mitochondria at reduced rates. This is, in part, because hypoxia induces the stabilization of the transcription factor HIF-1a (hypoxia-inducible factor-1a). One of the transcriptional targets of HIF-1a is pyruvate dehydrogenase kinase 1 (PDK1), which limits conversion of pyruvate into acetyl-CoA in mitochondria by phosphorylating the E1 subunit of PDH and thus inactivating the enzyme. Limiting pyruvate entry into mitochondria will also reduce glucose-derived carbons available for acetyl-CoA and ultimately lipid synthesis. |
