Hypoxia-Inducible Factor 1 Mediates Anoikis Resistance via Suppression of 5 Integrin

Hypoxia-inducible factor 1 mediates upregulation of telomerase (hTERT).

Hypoxia occurs during the development of the placenta in the first trimester and correlates with both trophoblast differentiation and the induction of telomerase activity through hTERT expression. We sought to determine the mechanism of regulation of hTERT expression during hypoxia. We show that hypoxia-inducible factor 1alpha (HIF-1alpha) and hTERT expression in the human placenta decrease wit...

Hypoxia-inducible factor 1

Naïve T cells activated by antigen-presenting cells (APC) can be differentiated into at least four major types of T-helper (T(H)) cells: T(H)1, T(H)2, T(H)17 and inducible regulatory T cells (iTreg) based on their unique cytokine production profiles and characteristic functions.(1) T(H)1 produce interferon-γ (IFNγ) and are important for protective immune responses to intracellular viral, bacter...

Hypoxia-inducible factor 1 mediates hypoxia-enhanced synthesis of progesterone during luteinization of granulosa cells

Hypoxia has been suggested to enhance progesterone (P4) synthesis in luteinizing granulosa cells (GCs), but the mechanism is unclear. The present study was designed to test the hypothesis that the hypoxia-induced increase in P4 synthesis during luteinization in bovine GCs is mediated by hypoxia-inducible factor 1 (HIF-1). GCs obtained from small antral follicles were cultured with 2 µg/ml insul...

Myeloid Hypoxia-Inducible Factor-1

Hypoxia-inducible factor-1 mediates adaptive developmental plasticity of hypoxia tolerance in zebrafish, Danio rerio.

In recent years, natural and anthropogenic factors have increased aquatic hypoxia the world over. In most organisms, the cellular response to hypoxia is mediated by the master regulator hypoxia-inducible factor-1 (HIF-1). HIF-1 also plays a critical role in the normal development of the cardiovascular system of vertebrates. We tested the hypothesis that hypoxia exposures which resulted in HIF-1...
