Mucosal Protection by Hypoxia-Inducible Factor Prolyl Hydroxylase Inhibition
Open accessAbstract
Background & aims A number of recent studies have implicated tissue hypoxia in both acute and chronic inflammatory diseases, particularly as they relate to mucosal surfaces lined by epithelial cells. In this context, a protective role for the transcriptional regulator hypoxia-inducible factor (HIF) was shown through conditional deletion of epithelial HIF-1alpha in a murine model of colitis. Here, we hypothesized that pharmacologic activation of HIF would similarly provide a protective adaptation to murine colitic disease.Methods For these purposes, we used a novel prolyl hydroxylase (PHD) inhibitor (FG-4497) that readily stabilizes HIF-1alpha and subsequently drives the expression downstream of HIF target genes (eg, erythropoietin).Results Our results show that the FG-4497-mediated induction of HIF-1alpha provides an overall beneficial influence on clinical symptoms [weight loss, colon length, tissue tumor necrosis factor-alpha (TNFalpha)] in murine trinitrobenzene sulfonic acid (TNBS) colitis, most likely because of their barrier protective function and wound healing during severe tissue hypoxia at the site of inflammation.Conclusions Taken together these findings emphasize the role of epithelial HIF-1alpha during inflammatory diseases in the colon and may provide the basis for a therapeutic use of PHD inhibitors in inflammatory mucosal disease.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
