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 and Hypoxia-Inducible Factors in Leukemias

Despite huge improvements in the treatment of leukemia, the percentage of patients suffering relapse still remains significant. Relapse most often results from a small number of leukemic stem cells (LSCs) within the bone marrow, which are able to self-renew, and therefore reestablish the full tumor. The marrow microenvironment contributes considerably in supporting the protection and developmen...

SnapShot: Hypoxia-Inducible Factors

Molecular oxygen (O2) is a key substrate for mitochondrial ATP production and numerous intracellular biochemical reactions. The maintenance of O2 homeostasis is therefore essential for the survival of most species. During O2 deprivation, mammalian cells rely on multiple adaptations mediated by the hypoxia-inducible factors (HIFs), mTOR, autophagy, and the ER stress response. This SnapShot will ...

Developmental Expression and Hypoxic Induction of Hypoxia Inducible Transcription Factors in the Zebrafish

The hypoxia inducible transcription factor (HIF) has been shown to coordinate the hypoxic response of vertebrates and is expressed in three different isoforms, HIF-1α, HIF-2α and HIF-3α. Knock down of either Hif-1α or Hif-2α in mice results in lethality in embryonic or perinatal stages, suggesting that this transcription factor is not only controlling the hypoxic response, but is also involved ...

Prolyl Hydroxylase 2 and Activates Hypoxic Response Melanoma Antigen-11 Inhibits the Hypoxia-Inducible Factor

Activation of hypoxia-inducible factors (HIF), responsible for tumor angiogenesis and glycolytic switch, is regulated by reduced oxygen availability. Normally, HIF-A proteins are maintained at low levels, controlled by site-specific hydroxylation carried out by HIF prolyl hydroxylases (PHD) and subsequent proteasomal degradation via the von HippelLindau ubiquitin ligase. Using a yeast two-hybri...
