Contribution of hypoxia inducible factor-1 during viral infections
Virulence, 2020 Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that plays critical roles during the cellular response to hypoxia. Under normoxic conditions, its function is tightly regulated by the degradation of its alpha subunit (HIF-1α), which impairs ...

Hypoxia-inducible factor-1 in tumour angiogenesis
World Journal of Gastroenterology, 2004 Hypoxia-inducible factor-1 (HIF-1), composed of HIF-alpha and HIF-beta subunits, is a heterodimeric transcriptional activator. In response to hypoxia, stimulation of growth factors, and activation of oncogenes as well as carcinogens, HIF-1alpha is overexpressed and/or activated and targets those genes which are required for angiogenesis, metabolic ...

Activation of Hypoxia-Inducible Factor-1 in Bacillary Angiomatosis [PDF]
Circulation, 2005 Background— Bartonella species are the only known bacterial pathogens causing vasculoproliferative disorders in humans (bacillary angiomatosis [BA]). Cellular and bacterial pathogenetic mechanisms underlying the induction of BA are largely unknown.

Synthesis of Neolamellarin A, an Inhibitor of Hypoxia-Inducible Factor-1 [PDF]
Natural Product Communications, 2009 Neolamellarin A, a metabolite isolated from the sponge Dendrilla nigra, was found to inhibit hypoxia-inducible factor-1 (HIF-1) activation by 26% at 10 μM concentration and inhibition of HIF-1 has become a major antitumor molecular target. Herein the first synthesis of neolamellarin A is described.

Regulation of Metabolism by Hypoxia-Inducible Factor 1 [PDF]
Cold Spring Harbor Symposia on Quantitative Biology, 2011 The maintenance of oxygen homeostasis is critical for survival, and the master regulator of this process in metazoan species is hypoxia-inducible factor 1 (HIF-1), which controls both O(2) delivery and utilization. Under conditions of reduced O(2) availability, HIF-1 activates the transcription of genes, whose protein products mediate a switch from ...

Hypoxia-induced signaling in angiogenesis : role of mTOR, HIF and Angiotensin II [PDF]
, 2007 This thesis includes the work of four different projects I have been following during my time as a PhD student; (1) the characterization of mTOR-associated signaling and endothelial cell proliferation in response to hypoxia, and (2) identification of ...
