Journal ArticleDOI
Targeting of HIF-alpha to the von Hippel-Lindau Ubiquitylation Complex by O2-Regulated Prolyl Hydroxylation
Panu Jaakkola,David R. Mole,Ya-Min Tian,Michael I. Wilson,Janine Gielbert,Simon J. Gaskell,Alex von Kriegsheim,Holger F. Hebestreit,Mridul Mukherji,Christopher J. Schofield,Patrick H. Maxwell,Christopher W. Pugh,Peter J. Ratcliffe +12 more
TL;DR: It is shown that the interaction between human pVHL and a specific domain of the HIF-1α subunit is regulated through hydroxylation of a proline residue by an enzyme the authors have termed Hif-α prolyl-hydroxylase (HIF-PH).
Journal ArticleDOI
The tumour suppressor protein VHL targets hypoxia-inducible factors for oxygen-dependent proteolysis
Patrick H. Maxwell,Michael S. Wiesener,Gin-Wen Chang,Steven C. Clifford,Emma C. Vaux,Matthew Edward Cockman,Charles C. Wykoff,Christopher W. Pugh,Eamonn R. Maher,Peter J. Ratcliffe,Peter J. Ratcliffe +10 more
TL;DR: It is indicated that the interaction between HIF-1 and pVHL is iron dependent, and that it is necessary for the oxygen-dependent degradation of HIF α-subunits, which may underlie the angiogenic phenotype of VHL-associated tumours.
Journal ArticleDOI
C. elegans EGL-9 and mammalian homologs define a family of dioxygenases that regulate HIF by prolyl hydroxylation.
Andrew C. R Epstein,Jonathan M. Gleadle,Luke A. McNeill,Kirsty S. Hewitson,J F O'Rourke,David R. Mole,Mridul Mukherji,Eric Metzen,Michael A Wilson,Anu Dhanda,Ya-Min Tian,Norma Masson,Donald L. Hamilton,Panu Jaakkola,Robert Barstead,Jonathan Hodgkin,Patrick H. Maxwell,Christopher W. Pugh,Christopher J. Schofield,Peter J. Ratcliffe +19 more
TL;DR: Direct modulation of recombinant enzyme activity by graded hypoxia, iron chelation, and cobaltous ions mirrors the characteristics of HIF induction in vivo, fulfilling requirements for these enzymes being oxygen sensors that regulate HIF.
Journal ArticleDOI
Oxygen Sensing by Metazoans: The Central Role of the HIF Hydroxylase Pathway
TL;DR: HIF plays a central role in the transcriptional response to changes in oxygen availability and is modulated by FIH1-mediated asparagine hydroxylation, and HIF-modulatory drugs are now being developed for diverse diseases.
Journal ArticleDOI
Role of HIF-1alpha in hypoxia-mediated apoptosis, cell proliferation and tumour angiogenesis.
Peter Carmeliet,Yuval Dor,Jean-Marc Herbert,Dai Fukumura,Koen Brusselmans,Mieke Dewerchin,Michal Neeman,Françoise Bono,Rinat Abramovitch,Patrick H. Maxwell,Cameron J. Koch,Peter J. Ratcliffe,Lieve Moons,Rakesh K. Jain,Desire Collen,Eli Keshert +15 more
TL;DR: It is shown that hypoxia and hypoglycaemia reduce proliferation and increase apoptosis in wild-type (Hif-1α+/+) embryonic stem (ES) cells, but not in ES cells with inactivated HIF-1 α genes (HIF- 1α−/−), suggesting that there are at least two different adaptive responses to being deprived of oxygen and nutrients.
