Hypoxia-inducible factor 1-alpha, also known as HIF-1-alpha, is a subunit of a heterodimeric transcription factor hypoxia-inducible factor 1 that is encoded by the HIF1A gene. [5] [6] [7] The Nobel Prize in Physiology or Medicine 2019 was awarded for the discovery of HIF.

Mar 30, 2025 · HIF1A (Hypoxia Inducible Factor 1 Subunit Alpha) is a Protein Coding gene. Diseases associated with HIF1A include Pheochromocytoma and Retinal Ischemia. Among its related pathways are Signaling by PTK6 and Autodegradation of the E3 ubiquitin ligase COP1.

Recently, it has been identified that hypoxia-inducible factor-1 alpha (HIF-1α) is a major transcriptional regulatory factor that responds to hypoxic environments and modulates the expression of many genes in the organism and is closely associated with the biological behavior of malignant tumors. 1,2 Importantly, HIF-1α is commonly highly expres...

Hypoxia-inducible factor-1 (HIF-1) has been recognized as an important cancer drug target. This review summarizes the role and regulation of the HIF-1 α in cancer and recent therapeutic approaches targeting this important pathway. 1. The role of HIF-1 α pathway in cellular adaptation to hypoxic stress.

Feb 15, 2008 · In keeping with the complexity of the hypoxic response, three principal isoforms of HIF- α exist (HIF-1 α, HIF-2 α and HIF-3 α). All are encoded by distinct gene loci and further diversity is...

HIF-1α can function as a multifunctional supplement for hypoxia since it regulates hypoxic genes and the environment, including angiogenesis, erythropoiesis, and glycolysis [3].

HIF1A promotes miR-210/miR-424 transcription to modulate the angiogenesis in HUVECs and HDMECs via sFLT1 under hypoxic stress. HIF-1alpha and Nrf2 regulates hypoxia induced overexpression of DDAH1 through promoter activation in prostate cancer.

Sep 1, 1998 · The HIF1A gene encodes the HIF-1alpha subunit of hypoxia-inducible factor 1, a transcription factor that is essential for cardiovascular development and systemic O2 homeostasis.

Jul 21, 2016 · Hypoxia-inducible factor-1α (HIF-1α) is a key transcription factor in cellular responses to hypoxia. We investigated the hypothesis that HIF-1α has effects on macrophage biology that promotes atherogenesis in mice.

Jun 9, 2023 · HIF-1α regulates the immune response, viability, migration, phenotypic plasticity, and metabolism of macrophages. Specifically, macrophage-derived HIF-1α can prevent excessive pro-inflammatory responses by attenuating the transcriptional activity of nuclear factor-kappa B in vivo and in vitro.
