«Our work suggests that AMPK signaling may be one of the links between the loss of dystrophin and the impaired nNOS function that is seen in muscular dystrophy,» says Michele, senior study author and professor of molecular & integrative physiology and internal medicine at the University of Michigan.
Experiments have shown treatment with sildenafil significantly improved heart function in mice missing the dystrophin protein.
«AMPK normally helps to turn on nNOS function in muscle cells, for instance when we exercise, and when dystrophin is lost, AMPK does not turn on appropriately.»
These splice sites instruct the genetic machinery to build abnormal dystrophin molecules, but once the gene is successfully edited it expresses a much - improved dystrophin protein product, enhancing the function of the muscle tissue.
12 guide RNAs developed to find mutation «hotspots» along the dystrophin gene helped rescue cardiac function to near - normal levels in human heart muscle tissue.
Moreover, large - scale screens in the C. elegans DMD model allowed identifying genetic and pharmacologic suppressors of dystrophin - dependent muscle degeneration; some of them positively impact mitochondrial functions or structure under stress conditions, or are involved in signaling pathways linked to mitochondria, and others are associated to proteostasis pathways such as autophagy, proteasome and Unfolded Protein Response (UPR).
Campbell and his colleagues began their work by genetically engineering knockout mice that lacked a functioning protein called δ - sarcoglycan, which is part of a larger molecular assemblage called the dystrophin - glycoprotein complex (DGC).
DMD is caused by the absence of a protein called dystrophin which is essential in maintaining the healthy function of muscles in the body.
«This evidence supports our concept of «tipping point» where the number and extent of fiber branching reaches a level where the branching itself terminally compromises muscle function, irrespective of the absence of dystrophin,» the researchers wrote.
«Our work suggests that AMPK signaling may be one of the links between the loss of dystrophin and the impaired nNOS function that is seen in muscular dystrophy,» says Michele, senior study author and associate professor of molecular & integrative physiology and internal medicine at the University of Michigan.
The technique partially restored not only functional dystrophin expression, but also dystrophic muscle function.
Muscular dystrophy in dogs is caused by an inherited mutated dystrophin gene that disrupts the dystrophin protein production, resulting in loss of muscle function.
