Hif-2alpha ros
WebIn the next section, we discuss how mitochondrial respiration, ROS and TCA cycle metabolites regulate HIF-α hydroxylation. Mitochondrial ROS regulates HIFs. During mitochondrial respiration under normal oxygen conditions, O 2 is chemically reduced to water by the transfer of four electrons at cytochrome oxidase.
