Abstract

Key points: Reactive oxygen species (ROS) and nitric oxide (NO) regulate exercise‐induced nuclear factor erythroid 2‐related factor 2 (NFE2L2) expression in skeletal muscle. NFE2L2 is required for acute exercise‐induced increases in skeletal muscle mitochondrial biogenesis genes, such as nuclear respiratory factor 1 (NRF‐1) and mitochondrial transcription factor A, and anti‐oxidant genes, such as superoxide dismutase (SOD)1, SOD2 and catalase. Following exercise training mice with impaired NFE2L2 expression have reduced exercise performance, energy expenditure, mitochondrial volume and anti‐oxidant activity. In muscle cells, ROS and NO can regulate mitochondrial biogenesis via a NFE2L2/NRF‐1‐dependent pathway. Regular exercise induces adaptations to skeletal muscle, which can include mitochondrial biogenesis and enhanced anti‐oxidant reserves. These adaptations and others are at least partly responsible for the improved health of physically active individuals. Reactive oxygen species (ROS) and nitric oxide (NO) are produced during exercise and may mediate the adaptive response to exercise in skeletal muscle. However, the mechanisms through which they act are unclear. In the present study, we aimed to determine the role of the redox‐sensitive transcription factor nuclear factor erythroid‐derived 2‐like 2 (NFE2L2) in acute exercise‐ and training‐induced mitochondrial biogenesis and the anti‐oxidant response. We report that ROS and NO regulate acute exercise‐induced expression of NFE2L2 in mouse skeletal muscle and muscle cells, and that deficiency in NFE2L2 prevents normal acute treadmill exercise‐induced increases in mRNA of the mitochondrial biogenesis markers, nuclear respiratory factor 1 (NRF‐1) and mitochondrial transcription factor A (mtTFA), and the anti‐oxidants superoxide dismutase (SOD) 1 and 2, as well as catalase, in mouse gastrocnemius muscle. Furthermore, after 5 weeks of treadmill exercise training, mice deficient in NFE2L2 had reduced exercise capacity and whole body energy expenditure, as well as skeletal muscle mitochondrial mass and SOD activity, compared to wild‐type littermates. In C2C12 myoblasts, acute treatment with exogenous H 2 O 2 (ROS)‐ and diethylenetriamine/NO adduct (NO donor) induced increases in mtTFA, which was prevented by small interfering RNA and short hairpin RNA knockdown of either NFE2L2 or NRF‐1. Our results suggest that, during exercise, ROS and NO can act via NFE2L2 to functionally regulate skeletal muscle mitochondrial biogenesis and anti‐oxidant defence gene expression.

  • Antioxidant supplements or the deletion of NFE2L2 can block acute exercise-induced increases in PGC1α and mitochondrial biogenesis.

    “Previous studies have shown that antioxidant supplements or the deletion of NFE2L2 can block acute exercise–induced increases in PGC1α and mitochondrial biogenesis (5–7).”
  • NFE2L2 is required for the induction of mitochondrial biogenesis after exercise and for optimal exercise performance.

    “NFE2L2 is thought to be required for the induction of mitochondrial biogenesis after exercise and for optimal exercise performance (3, 7).”
  • Exercise induces Nfe2l2 gene expression, whereas ROS generated during exercise would be expected to increase NFE2L2 stability.

    “Exercise induces Nfe2l2 gene expression (7), whereas ROS generated during exercise would be expected to increase NFE2L2 stability (4, 30).”
  • Contracting muscle generates ROS and this is accompanied by increased antioxidant defense orchestrated by NFE2L2.

    “It is well established that contracting muscle generates ROS and that this is accompanied by increased antioxidant defense orchestrated by NFE2L2 (2, 7, 36).”
  • The stress imposed by exercise training is recognized as the most effective stimulus for mitochondrial biogenesis as part of redox-sensitive adaptation, resulting in enhanced mitochondrial function across the life course.

    “Indeed, the stress imposed by exercise training is recognized as the most effective stimulus for mitochondrial biogenesis as part of redox-sensitive adaptation [96,97,98], resulting in enhanced mitochondrial function across the life course [99,100].”

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.
