HIF-2α activation tips the balance toward ROS-induced cell death and thus provides specificity to cancer cells compared with normal tissues. We show that HIF-2α potentiates cell death via ferroptosis activators and DMF, and both pathways require ...
WebROS are a well-known upstream regulator that can stabilize HIF levels by preventing HIF degradation or increasing HIF gene expression (26, 47). A study in Caenorhabditis elegans has shown that ROS affects metabolic rate by regulating HIF protein levels ( 48 ).

WebDiscovery. The HIF transcriptional complex was discovered in 1995 by Gregg L. Semenza and postdoctoral fellow Guang Wang. In 2016, William Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza were presented the Lasker Award for their work in elucidating the role of HIF-1 in oxygen sensing and its role in surviving low oxygen conditions. In 2024, the … WebAbstract: Hypoxia-inducible factor-1 (HIF-1) is responsible for cellular adaptations to hypoxia. While oxygen (O 2) negatively regulates its stability, many other factors affect HIF-1 stability and activity, including nitric oxide (NO). NO derived from l-arginine and nitrite (NO 2–) could nitrosylate or nitrate HIF-1 and multiple proteins ...
