Pyruvaldehyde 108-121 glyoxalase 1 Rattus norvegicus 71-76 21124777-4 2010 In this work, we identified a new molecular mechanism whereby methylglyoxal (MGO), which accumulates in high-glucose conditions, led to a rapid proteasome-dependent degradation of HIF-1alpha under hypoxia. Pyruvaldehyde 62-75 hypoxia inducible factor 1 subunit alpha Homo sapiens 180-190 21124777-7 2010 Consistently, silencing of endogenous CHIP and overexpression of glyoxalase I both stabilized HIF-1alpha under hypoxia in the presence of MGO. Pyruvaldehyde 138-141 glyoxalase I Homo sapiens 65-77 21124777-4 2010 In this work, we identified a new molecular mechanism whereby methylglyoxal (MGO), which accumulates in high-glucose conditions, led to a rapid proteasome-dependent degradation of HIF-1alpha under hypoxia. Pyruvaldehyde 77-80 hypoxia inducible factor 1 subunit alpha Homo sapiens 180-190 21124777-5 2010 Significantly, MGO-induced degradation of HIF-1alpha did not require the recruitment of the ubiquitin ligase pVHL nor did it require hydroxylation of the proline residues P402/P564 of HIF-1alpha.
