FACTOR INHIBITING HIF-1 ALPHA WITH FUMARATE

OverviewOverview

In humans both the levels and activity of the alpha-subunit of the, hypoxia-inducible transcription factor (HIF-alpha) are regulated by its, post-translation hydroxylation as catalyzed by iron- and 2-oxoglutarate, (2OG)-dependent prolyl and asparaginyl hydroxylases (PHD1-3 and, factor-inhibiting HIF (FIH), respectively). One consequence of hypoxia is, the accumulation of tricarboxylic acid cycle intermediates (TCAIs). In, vitro assays were used to assess non-2OG TCAIs as inhibitors of purified, PHD2 and FIH. Under the assay conditions, no significant FIH inhibition, was observed by the TCAIs or pyruvate, but fumarate, succinate, and, isocitrate inhibited PHD2. Mass spectrometric analyses under nondenaturing, conditions were used to investigate the binding of TCAIs to PHD2 and, supported ... [(full description)]
