1 Proline-hydroxylated hypoxia-inducible factor 1alpha (HIF-1alpha) upregulation in human tumours. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
2 Proline-hydroxylated hypoxia-inducible factor 1alpha (HIF-1alpha) upregulation in human tumours. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
3 To this end we optimised antibodies against the proline-hydroxylated forms of HIF-1alpha for use in formalin fixed paraffin embedded (FFPE) immunohistochemistry to assess effects in tumour cells in vivo. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
4 We found that HIF-1alpha proline-hydroxylated at both VHL binding sites (Pro402 and Pro564), was present in hypoxic regions of a wide range of tumours, tumour xenografts and in moderately hypoxic cells in vitro. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
5 Our conclusions are that the degradation of proline-hydroxylated HIF-1alpha may be rate-limited in tumours and therefore provides new insights into mechanisms of HIF upregulation. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
6 Persistence of proline-hydroxylated HIF-1alpha in perinecrotic areas suggests there is adequate oxygen to support prolyl hydroxylase domain (PHD) activity and proline-hydroxylated HIF-1alpha may be the predominant form associated with the poorer prognosis that higher levels of HIF-1alpha confer. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
7 Persistence of proline-hydroxylated HIF-1alpha in perinecrotic areas suggests there is adequate oxygen to support prolyl hydroxylase domain (PHD) activity and proline-hydroxylated HIF-1alpha may be the predominant form associated with the poorer prognosis that higher levels of HIF-1alpha confer. Proline hypoxia inducible factor 1 subunit alpha Homo sapiens
