TSGA10 prevents nuclear localization of the hypoxia-inducible factor (HIF)-1alpha.

The hypoxia-inducible factor (HIF)-1 is a transcriptional regulator of genes involved in oxygen homeostasis. We previously described testis-specific isoforms of HIF-1alpha (mHIF-1alphaI.1 and hHIF-1alphaTe). Using mHIF-1alpha exon I.1 knock-out mice we confirmed the specific expression of mHIF-1alphaI.1 in the sperm tail. A protein-protein interaction between HIF-1alpha and the testis specific ...

Ubiquitin-specific protease 19 (USP19) regulates hypoxia-inducible factor 1α (HIF-1α) during hypoxia.

A proper cellular adaptation to low oxygen levels is essential for processes such as development, growth, metabolism, and angiogenesis. The response to decrease in oxygen supply, referred to as hypoxia, is also involved in numerous human diseases including cancer, inflammatory conditions, and vascular disease. The hypoxia-inducible factor 1-α (HIF-1α), a key player in the hypoxic response, is k...

The role of reactive oxygen species in the stabilisation of hypoxia-inducible factor-1α (HIF-1α)

4 Abstract: At physiological oxygen concentrations ([O2]) hypoxia-inducible factor-1α (HIF-1α) is constantly hydroxylated and thus prepared for proteosomal degradation through the action of the prolyl hydroxylases (PHDs) (Jiang et al., 1996). In hypoxia, however, the oxygen-sensitive PHDs are inhibited and HIF-1α is stabilised. Other agents, including cytokines and growth factors have been show...

A dynamic model of the hypoxia-inducible factor 1α (HIF-1α) network.

Activation of the hypoxia-inducible factor (HIF) pathway is a critical step in the transcriptional response to hypoxia. Although many of the key proteins involved have been characterised, the dynamics of their interactions in generating this response remain unclear. In the present study, we have generated a comprehensive mathematical model of the HIF-1α pathway based on core validated component...

Methylation impact analysis of erythropoietin (EPO) Gene to hypoxia inducible factor-1α (HIF-1α) activity

Erythropoietin (EPO) is a glycoprotein hormone that play a role as key regulator in the production of red blood cells. The promoter region of EPO is methylated in normoxic (non-hypoxia) condition, but not in hypoxic condition. Methylation of the EPO enhancer region decline the transcription activity of EPO gene. The aim of this study is to investigate how different methylation percentage affect...
