Abstract

Objective Mitochondria are organelles primarily responsible for energy production, and recent evidence indicates that alterations in size, shape, location, and quantity occur in response to fluctuations in energy supply and demand. We tested the impact of acute and chronic exercise on mitochondrial dynamics signaling and determined the impact of the mitochondrial fission regulator Dynamin related protein (Drp)1 on exercise performance and muscle adaptations to training. Methods Wildtype and muscle-specific Drp1 heterozygote (mDrp1 +/− ) mice, as well as dysglycemic (DG) and healthy normoglycemic men (control) performed acute and chronic exercise. The Hybrid Mouse Diversity Panel, including 100 murine strains of recombinant inbred mice , was used to identify muscle Dnm1L (encodes Drp1)-gene relationships. Results Endurance exercise impacted all aspects of the mitochondrial life cycle , i.e. fission-fusion, biogenesis, and mitophagy . Dnm1L gene expression and Drp1 Ser616 phosphorylation were markedly increased by acute exercise and declined to baseline during post-exercise recovery. Dnm1L expression was strongly associated with transcripts known to regulate mitochondrial metabolism and adaptations to exercise. Exercise increased the expression of DNM1L in skeletal muscle of healthy control and DG subjects, despite a 15% ↓( P = 0.01) in muscle DNM1L expression in DG at baseline. To interrogate the role of Dnm1L further, we exercise trained male mDrp1 +/− mice and found that Drp1 deficiency reduced muscle endurance and running performance, and altered muscle adaptations in response to exercise training. Conclusion Our findings highlight the importance of mitochondrial dynamics, specifically Drp1 signaling, in the regulation of exercise performance and adaptations to endurance exercise training.

Figure 1 Schematic depicting exercise protocols for humans and mice. (A) Acute and chronic cyclying exercise was performed by healthy normoglycemic (control) and Dysglycemic (DG) men, age 40–65 years (N = 13/group). (B) Wildtype mice were studied during acute (EX45, EX90, EX90 + 3 h Rest) and chronic exercise (TRN, TRN + EX90) experiments 1–3. Exercise training (TRN) was achieved using voluntary running wheels for 30 days. Muscle was harvested 30 h after the last bout of exercise. An additional cohort of TRN mice performed an acute bout of moderate intensity treadmill running (TRN + EX90). (C) A panel of recombinant inbred strains of mice (84 strains of male and female mice, N = 4 mice/strain and a 15-strain subset of female mice, N = 4 mice/strain), the UCLA HMDP, were studied to determine the relationship between sex and Dnm1L expression and Dnm1L gene–gene relationships. (D) Muscle-specific Drp1 heterozygous (mDrp1+/−) mice were studied at rest and following EX90 and TRN.

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.
