HIF-α Prolyl Hydroxylase Inhibitors and Their Implications for Biomedicine: A Comprehensive Review
Oxygen is essential for the maintenance of the body. Living organisms have evolved systems to secure an oxygen environment to be proper. Hypoxia-inducible factor (HIF) plays an essential role in this process; it is a transcription factor that mediates ...

Hypoxia-inducible factor-1 in tumour angiogenesis
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 ...

Contribution of hypoxia inducible factor-1 during viral infections
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 ...

Activation of Hypoxia-Inducible Factor-1 in Bacillary Angiomatosis [PDF]
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.

Hypoxia‐inducible factor 1 and cancer pathogenesis [PDF]
AbstractHypoxia‐inducible factor 1 (HIF‐1) is a transcriptional activator that mediates adaptive responses to hypoxia. HIF‐1 activity is increased in the majority of human cancers as a result of genetic alterations and intratumoral hypoxia. HIF‐1 activates the transcription of genes that increase O2 availability by stimulating angiogenesis or that ...

Synthesis of Neolamellarin A, an Inhibitor of Hypoxia-Inducible Factor-1 [PDF]
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.
