Supplementary information

HIF-1 alpha also known as hypoxia-inducible factor 1-alpha is a transcription factor critical in cellular response to low oxygen levels. Its molecular weight usually ranges from 93 to 120 kDa. You can find HIF-1 alpha expressed in tissues throughout the body but its expression significantly increases under hypoxic conditions. Researchers often use the HIF-1a ELISA to measure its expression levels. HIF-1 alpha forms a complex with other proteins to perform its functions effectively.

Biological function summary

HIF-1 alpha regulates gene expression in response to hypoxic conditions in cells. It forms a complex with HIF-1 beta to activate transcription of various genes involved in energy metabolism angiogenesis and erythropoiesis. HIF-1 alpha enables cells to adapt to reduced oxygen availability allowing for cellular survival and function under stress. It plays an important role in promoting the expression of genes like VEGF and EPO which are important for vascular and red blood cell development respectively.

Pathways

HIF-1 alpha plays an integral role in the hypoxia signaling pathway and the glycolytic pathway. In the hypoxia signaling pathway HIF-1 alpha partners with VHL (Von Hippel-Lindau) protein that regulates its degradation under normal oxygen conditions. When oxygen levels drop HIF-1 alpha avoids degradation stabilizes and translocates into the nucleus to initiate transcription of hypoxia-responsive genes. The glycolytic pathway involvement highlights its function in adapting energy production under hypoxic conditions through collaboration with enzymes and transporters associated with glycolysis.

HIF-1 alpha has been implicated in cancer and ischemic diseases. Its role in promoting angiogenesis and metabolic adaptation makes it a contributor to tumor growth and survival collaborating with oncogenes such as c-Myc. In ischemic diseases like stroke or myocardial infarction HIF-1 alpha's ability to induce protective responses can mitigate tissue damage through regulation of survival pathways. Understanding these interactions helps in the development of therapeutic strategies targeting HIF-1 alpha in disease contexts.

Target data

The protein expressed by the gene HIF1A functions as a master transcriptional regulator of the adaptive response to hypoxia, activating the transcription of over 40 genes under hypoxic conditions, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and others. These genes' protein products enhance oxygen delivery or facilitate metabolic adaptation to hypoxia. HIF1A is crucial for embryonic vascularization, tumor angiogenesis, and ischemic disease pathophysiology. Its activation requires transcriptional coactivators like CREBBP and EP300, with activity enhanced by interactions with NCOA1 and/or NCOA2. Interaction with redox regulatory protein APEX1 activates CTAD and enhances activation by NCOA1 and CREBBP. Additionally, HIF1A is involved in axonal distribution and mitochondrial transport in neurons during hypoxia. In the context of microbial infection, specifically human coronavirus SARS-CoV-2, HIF1A is necessary for glycolysis induction in monocytes, leading to a proinflammatory state, inducing expression of ACE2, cytokines, and promoting virus replication and monocyte inflammatory response.
