WebHIF-1 and metabolism. (A) Regulation of HIF-1α protein synthesis and stability and HIF-1-dependent metabolic reprogramming.The rate of translation of HIF-1α mRNA into protein in cancer cells is dependent upon the activity of the mammalian target of rapamycin (mTOR), which is determined by the activity of upstream tumor suppressor proteins (green ovals) … Web1 de set. de 2024 · Interestingly, global loss of FIH, the other HIF hydroxylase, leads to an increased metabolic rate and insulin sensitivity that does not coincide with increases in glycolysis, fatty acid oxidation, or HIF1 target gene expression (90, 91). Rather, FIH appears to regulate mitochondrial ROS production and glycogen storage .
