Identification of Novel Small Molecule Inhibitors of Hypoxia-Inducible Factor-1 That Differentially Block Hypoxia-Inducible Factor-1 Activity and Hypoxia-Inducible Factor-1α Induction in Response to Hypoxic Stress and Growth Factors

Identification of Novel Small Molecule Inhibitors of Hypoxia- Inducible Factor-1 That Differentially Block Hypoxia-Inducible Factor-1 Activity and Hypoxia-Inducible Factor-1A Induction in Response to Hypoxic Stress and Growth Factors

Hypoxia-inducible factor-1 (HIF-1) is a transcriptional complex that is activated in response to hypoxia and growth factors. HIF-1 plays a central role in tumor progression, invasion, and metastasis. Overexpression of the HIF-1A subunit has been observed in many human cancers and is associated with a poor prognostic outcome with conventional treatments. Targeting HIF-1 using novel small molecul...

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...

Identification of novel small-molecule inhibitors of hypoxia-inducible factor-1 transactivation and DNA binding.

Hypoxia-inducible factor-alpha (Hif-alpha) plays an important role in tumor growth by increasing resistance to apoptosis and the production of angiogenic factors, such as vascular endothelial growth factor (VEGF). Therefore, Hif-alpha is an attractive target for development of novel cancer therapeutics. We have generated Chinese hamster ovary cells, which stably express luciferase reporter cons...

The Effect of Aerobic Training on Tumor Necrosis Factor alpha, Hypoxia-Inducible Factor-1 alpha & Vascular Endothelial Growth Factor Gene Expression in Cardiac Tissue of Diabetic Rats

Objective: The goal of this research was to determine the influence of 4 weeks aerobic training on gene expression of tumor necrosis factor alpha (TNF-α), hypoxia-inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in the cardiac tissue of diabetic rats. Materials and Methods: In an experimental study, 30 male wistar rats were partitioned into three groups (n=10), d...
