Abstract

Ischaemia-reperfusion injury occurs when the blood supply to an organ is disrupted and then restored, and underlies many disorders, notably heart attack and stroke. While reperfusion of ischaemic tissue is essential for survival, it also initiates oxidative damage, cell death and aberrant immune responses through the generation of mitochondrial reactive oxygen species (ROS). Although mitochondrial ROS production in ischaemia reperfusion is established, it has generally been considered a nonspecific response to reperfusion. Here we develop a comparative in vivo metabolomic analysis, and unexpectedly identify widely conserved metabolic pathways responsible for mitochondrial ROS production during ischaemia reperfusion. We show that selective accumulation of the citric acid cycle intermediate succinate is a universal metabolic signature of ischaemia in a range of tissues and is responsible for mitochondrial ROS production during reperfusion. Ischaemic succinate accumulation arises from reversal of succinate dehydrogenase, which in turn is driven by fumarate overflow from purine nucleotide breakdown and partial reversal of the malate/aspartate shuttle. After reperfusion, the accumulated succinate is rapidly re-oxidized by succinate dehydrogenase, driving extensive ROS generation by reverse electron transport at mitochondrial complex I. Decreasing ischaemic succinate accumulation by pharmacological inhibition is sufficient to ameliorate in vivo ischaemia-reperfusion injury in murine models of heart attack and stroke. Thus, we have identified a conserved metabolic response of tissues to ischaemia and reperfusion that unifies many hitherto unconnected aspects of ischaemia-reperfusion injury. Furthermore, these findings reveal a new pathway for metabolic control of ROS production in vivo, while demonstrating that inhibition of ischaemic succinate accumulation and its oxidation after subsequent reperfusion is a potential therapeutic target to decrease ischaemia-reperfusion injury in a range of pathologies.

  • These ischemic conditions promote reverse electron transfer upon reperfusion, resulting in significant superoxide production from complex I.

    “Together, these conditions promote reverse electron transfer upon reperfusion, which results in significant superoxide production from complex I (171).”
  • Reverse electron transport ROS generation occurs when succinate is present in high concentration and is responsible in vivo for ROS generated after ischemia upon reperfusion.

    “This type of ROS generation occurs when succinate, the substrate for complex II, is present in high concentration and is responsible in vivo for the ROS generated after ischemia upon reperfusion (171, 172).”
  • α-KG and succinate regulate the activity of JMJD histone demethylases and TET family 5mC hydroxylases.

    “α-KG and succinate can regulate the activity of other members of the α-KGDD family of enzymes, in particular those involved in the regulation of histone and DNA demethylation, the α-KG-dependent Jumonji C-domain containing histone demethylases (JMJDs) and the Ten eleven translocation (TET) family of 5mC hydroxylases, which play a role in DNA demethylation.”
  • Numerous metabolic pathways have been implicated in the metabolic reprogramming of immune cells, particularly those that regulate succinate levels, which can influence HIF signaling or other pathways.

    “Numerous metabolic pathways have been implicated in the metabolic reprogramming of immune cells, in particular those that regulate succinate levels, which, in turn, can influence HIF signaling or other pathways (13,25,40,41).”
  • Inhibition of SDH by endogenously produced itaconate may buffer against potential oxidative damage that can occur under ischemia/reperfusion conditions.

    “Notably, SDH inhibition protected against brain injury after ischemia/reperfusion (40,41), suggesting that inhibition of SDH by endogenously produced itaconate may buffer against potential oxidative damage that can occur under such conditions.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
