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...
متن کاملThe 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...
متن کاملHypoxia-inducible factor-1 (HIF-1).
Adaptation to low oxygen tension (hypoxia) in cells and tissues leads to the transcriptional induction of a series of genes that participate in angiogenesis, iron metabolism, glucose metabolism, and cell proliferation/survival. The primary factor mediating this response is the hypoxia-inducible factor-1 (HIF-1), an oxygen-sensitive transcriptional activator. HIF-1 consists of a constitutively e...

متن کاملPosttranslational hydroxylation of ankyrin repeats in IkappaB proteins by the hypoxia-inducible factor (HIF) asparaginyl hydroxylase, factor inhibiting HIF (FIH).
Studies on hypoxia-sensitive pathways have revealed a series of Fe(II)-dependent dioxygenases that regulate hypoxia-inducible factor (HIF) by prolyl and asparaginyl hydroxylation. The recognition of these unprecedented signaling processes has led to a search for other substrates of the HIF hydroxylases. Here we show that the human HIF asparaginyl hydroxylase, factor inhibiting HIF (FIH), also e...
