Web1 de jun. de 2024 · HIF-1 and HIF-2, the most extensively studied HIF transcription factors, facilitate oxygen delivery and cellular adaptation to hypoxia by regulating a wide spectrum of hypoxia responses such as angiogenesis, anaerobic glucose metabolism, mitochondrial biogenesis, and others. 18 The list of genes that are directly HIF-regulated is large and … WebFigure 3 Role of CircRNA-mediated HIF and S6K/S6 pathways in glucose metabolism in tumor cells. CircRNAs can regulate HIF-1α protein synthesis and stability, thereby modulating HIF-1-mediated metabolic reprogramming. HIF-1α plays a key role in stimulating glycolic enzymes and in blocking mitochondrial activity.
