Key result
In a mouse model of Duchenne muscular dystrophy, selective mitochondrial dysfunction and elevated H2O2 emission preceded the onset of overt cardiomyopathy and cardiac remodelling at 4 weeks of age.
Why the study?
Most patients with Duchenne muscular dystrophy develop cardiomyopathy, but the contribution of mitochondrial dysfunction prior to the onset of cardiomyopathy remains unknown.
No takes yet. Share an insight, caveat, or question.
Mitochondrial impairments may precede cardiomyopathy in DMD; leaves open whether targeting respiratory control or H₂O₂ alters progression.
Hughes et al. (2019) studied Duchenne muscular dystrophy. DMD mutation (D2.B10-DMD mdx /2J mice) was evaluated on Mitochondrial bioenergetics (ADP-stimulated respiration and H2O2 emission). In a mouse model of Duchenne muscular dystrophy, selective mitochondrial dysfunction and elevated H2O2 emission preceded the onset of overt cardiomyopathy and cardiac remodelling at 4 weeks of age.
