Hypoxia-Inducible Factors in Cancer

Cancer Research, 2022
Abstract Low oxygen concentrations (hypoxia) are detrimental to most species on Earth; thus, cells have evolved with adaptations allowing them to withstand transient hypoxia. As with other survival pathways, cancer cells have co-opted these mechanisms to keep up with the metabolic demands of rapid growth and proliferation in harsh tumor ...

Hypoxia and Hypoxia-Inducible Factors in Leukemias [PDF]

open access: yesFrontiers in Oncology, 2016
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.

Hypoxia-inducible factors and cancer

Clinical and Translational Oncology, 2007
Decreased oxygen availability is a common feature during embryonic development as well of malignant tumours. Hypoxia regulates many transcription factors, and one of the most studied is the hypoxia-inducible factor (HIF). As a consequence of HIF stabilisation, the cell constitutively upregulates the hypoxic programme resulting in the expression of ...

Hypoxia-inducible factor in brain

2001
HIF-1 is composed of HIF-1alpha and HIF-1beta protein subunits. HIF-1 is induced by hypoxia and binds to promoter/enhancer elements and stimulates the transcription of hypoxia-inducible target genes. Because HIF-1 activation might promote cell survival in hypoxic tissues, we studied the effect of stroke on the expression of HIF-1alpha, HIF-1beta and ...

Mitochondria and Hypoxia‐induced Gene Expression Mediated by Hypoxia‐inducible Factors

Annals of the New York Academy of Sciences, 2008
The influence of mitochondrial activity on gene expression programs, particularly those involved in neuroprotection and repair, is likely to play an important role in the pathophysiology of neurodegenerative diseases. One such gene expression program is activated by the cellular pathway that senses a decrease in optimal oxygen levels and leads to ...

Hypoxia-induced radioresistance is independent of hypoxia-inducible factor-1A in vitro

International Journal of Radiation Oncology*Biology*Physics, 2005
We sought to determine whether hypoxia-induced radioresistance is mediated by the transcription factor hypoxia-inducible factor-1alpha (HIF-1alpha).We used 2 mouse embryonic fibroblast cell lines transformed with H-ras and TAg, 1 HIF-1alpha+/+ and the other HIF-1alpha-/-.
