Abstract

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by severe mitochondrial dysfunction, associated with the production of mitochondrial reactive oxygen species (mROS). The substantial generation of mROS in the MASH liver, resulting from lipid surplus and electron transport chain (ETC) overload, impairs mitochondrial structure and functionality, thereby contributing to the development of severe hepatic steatosis and inflammation. Regular exercise represents an effective strategy for the treatment of MASH. Understanding the effects of exercise on oxidative stress and mitochondrial function is essential for effective treatment of MASH. This article reviews the pathological alterations in mitochondrial β-oxidation, ETC efficiency and mROS production within MASH liver. Additionally, it discusses how exercise influences the redox state and mitochondrial quality control mechanisms-such as biogenesis, mitophagy, fusion, and fission-within the MASH liver. The article emphasizes the importance of in-depth studies on exercise-induced MASH mitigation through the enhancement of mitochondrial redox balance, quality control, and function. Exploring the relationship between exercise and hepatic mitochondria could provide valuable insights into identifying potential therapeutic targets for MASH.

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.
