dc.description | Hypoxia inducible factor (HIF) is a heterodimer transcription factor composed of one
of three alpha (α) subunits and a beta (β) subunit. The expression of HIF-α is induced
under hypoxic conditions, HIF-1α and HIF-2α are shown to be regulator in
transcriptional response to hypoxia, they have similar protein structure (48% amino
acid sequence similarity), but different target genes and regulatory mechanism. HIF3α is the newest member of the family and its role is still unclear. HIF-1β is
constitutively expressed, which is a partner of aryl hydrocarbon receptor (AhR) it binds
to AhR helping its translocation to the nucleus, so it is also referred to as aryl
hydrocarbon nuclear translocator (ARNT). HIF-1α is encoded by HIF1A gene, which
is located in chromosome 14, that is expressed in most tissues with highest levels in
kidneys and heart | en_US |
dc.description.abstract | Our cells response to low oxygen tension (hypoxia) by transcriptional induction of a
series of genes, this induction is mediated by hypoxia-inducible factors (HIFs), which
are family of transcription factors consist of one of three α subunits (HIF-1α, HIF-2α,
HIF-3α) and β subunit (HIF-1β). HIF-1α expression is induced by hypoxia, it was found
that it is a master regulator of angiogenesis and plays a critical role in glucose metabolic
pathways which provide physiologic adaptation and cell survival during hypoxic
conditions. Clinical investigations have been shown a correlation between
overexpression of HIF-1 and aggressive cancer progression, which may be expected
considering the fact that cancer cells are known to be hypoxic. Thus, targeting HIF-1
could represent a novel approach to cancer therapy, as it allows for survival and
proliferation of cancerous cells due to its angiogenic and metabolic properties | en_US |
