Hif-1α metabolic pathways in human cancer

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. WebIDF-11774 inhibits angiogenesis, suppresses HIF-1α refolding, and stimulates proteosomal-mediated HIF-1α-degradation. 72 Additionally, IDF-11774 was shown to decrease the glucose-dependent energy metabolism. 72 This promising small-molecule inhibitor modulates both hypoxic regulators and glycolysis to prevent cancer cell growth.
