WebNational Center for Biotechnology Information WebThe ARNT gene encodes the aryl hydrocarbon receptor nuclear translocator protein that forms a complex with ligand-bound aryl hydrocarbon receptor (AhR), and is required for receptor function. The encoded protein has also been identified as the beta subunit of a heterodimeric transcription factor, hypoxia-inducible factor 1 (HIF1). A t(1;12)(q21;p13) …
WebHypoxia Inducible Factor 1. Hypoxia inducible factor 1 (HIF-1) is composed of two subunits, an oxygen-sensitive inducible factor (HIF-1α) and the constitutive HIF-1β (also known as AhR nuclear translocator (ARNT)), which may prove to be an important target in diseases that have a hypoxic component such as cancer (where the interior of a tumor is … Web18 de mai. de 2024 · The interaction of HIF-1α and HIF-1β is required for the transcriptional function of HIF-1; HIF-1α serves as the major regulatory subunit responsible for hypoxic …
Web1 de abr. de 2002 · Abstract. Hypoxia-inducible factor 1 (HIF-1) controls oxygen delivery (via angiogenesis) and metabolic adaptation to hypoxia (via glycolysis). HIF-1 consists of a constitutively expressed HIF-1β subunit and an oxygen- and growth-factor-regulated HIF-1α subunit. In xenografts, tumor growth and angiogenesis are correlated with HIF-1 … WebHypoxia-inducible factor. Hypoxia-inducible factors ( HIFs) are transcription factors that respond to decreases in available oxygen in the cellular environment, or hypoxia. [1] [2] …
Webwhere it binds to ARNT/HIF-1β, which is constitutively expressed, and recruits transcriptional cofactors such as CBP and p300. The heterodimer HIF binds to the hypoxic response elements (HREs) of target gene regulatory sequences, resulting in the transcription of genes implicated in the control of metabolism and angiogenesis, as well as
