Hypoxia-inducible factor 1? (HIF-1?) turnover is initiated by prolyl hydroxylases (PHD), which hydroxylate proline residues on HIF-1?, facilitating ubiquitination. PHD activity is linked to the tricarboxylic acid (TCA) cycle, since the intermediate ?-ketoglutarate is a PHD substrate and succinate and fumarate inhibit PHD. Mutations in enzymes associated with the TCA cycle occur in certain cancers.{21411} Octyl-?-ketoglutarate is a stable, cell-permeable form of ?-ketoglutarate which accumulates rapidly and preferentially in cells with a dysfunctional TCA cycle.{21289} When used at 1 mM, it stimulates PHD activity, increasing HIF-1? turnover.{21289,21410} In addition, octyl-?-ketoglutarate competitively blocks succinate- or fumarate-mediated inhibition of PHD.{21289}
