Study TitleEffects of Exercise on Dystrophic Mouse Heart Meabolome (part IX)
Study SummaryWe will use male C57BL10, mdx, and nNOS-/- mice (n = 10 each group) to characterize the skeletal and cardiac muscle metabolomes. Half of the mice in each group will remain sedentary while the other half will be subjected to a single bout of treadmill exercise to exhaustion. Mice will be euthanized immediately postexercise and blood, hearts, and hindlimb muscles will be harvested and frozen as detailed in the General Methods. The heart and gastrocnemius, soleus, and quadriceps muscles of one hindlimb will be sent to the Mayo Clinic Metabolomics Resource Core. The heart and quadriceps muscle will be used for untargeted metabolomics profiling (LC/MS) while the gastrocnemius and soleus muscles will be used for targeted analyses of amino acids plus amino metabolites, non-esterified fatty acids, and citric acid cycle intermediates.

Project Title:The dystrophic muscle metabolome: effects of exercise and NO donor therapy
Project Summary:In Duchenne and Becker muscular dystrophy (DMD, BMD), loss of the cytoskeletal protein dystrophin weakens the sarcolemma and disrupts cellular signaling, rendering the diseased muscles susceptible to contractioninduced damage. We and others have shown that loss of neuronal nitric oxide synthase (nNOSμ) from the sarcolemma of dystrophin-deficient muscle causes functional muscle ischemia during exercise due to unopposed sympathetic vasoconstriction, thereby exacerbating fatigue and injury of the diseased muscles. Genetic and pharmacologic strategies targeting nNOSμ-NO signaling ameliorate functional muscle ischemia, as well as many other features of the dystrophic phenotype in the mdx mouse model of DMD/BMD. These findings suggest that the therapeutic benefit of NO likely extends beyond its vascular effects. A growing body of evidence indicates that NO directly influences muscle metabolism through effects on glucose transport as well as mitochondrial biogenesis and function. Both nNOS-/- mice and mdx mice exhibit muscle mitochondrial dysfunction, decreased resistance to fatigue, and exercise-induced muscle injury, suggesting a causal role of nNOSμ-NO deficiency. However, the specific metabolic changes resulting from reduced NO signaling that might render dystrophic muscle susceptible to fatigue and use-dependent injury remain poorly defined. Therefore, the goal of this pilot metabolomics study is to identify the unique biochemical profiles of skeletal and cardiac muscles of mdx mice to gain further mechanistic insight into the pathophysiological role of NO deficiency in muscular dystrophy. In Aim 1, we will characterize the skeletal and cardiac muscle metabolomes of mdx and nNOS-/- mice at rest and following a single bout of treadmill exercise with the goal of discovering common metabolic signatures caused by loss of NO signaling. In Aim 2, we will evaluate the potential of a NO donor drug that is under development as a therapeutic for DMD/BMD to improve the skeletal and cardiac muscle metabolomes in mdx mice. As a result of this pilot study, we hope to gain new understanding of the metabolic derangements in dystrophin-deficient muscle, insight into the therapeutic effects of NO replacement, and to identify new pathogenic mechanisms and putative therapeutic targets that will form the basis of future grant applications.

Collection:

Collection ID:CO000670
Collection Summary:Blood and Tissue Harvesting: Mice will be euthanized and blood will be taken by cardiac puncture, centrifuged, and the plasma will be stored at -80ºC. The heart, diaphragm, and muscles of both hindlimbs (gastrocnemius, soleus, quadriceps) will be dissected and snap frozen in liquid nitrogen. Tibialis anterior and plantaris muscles from both hindlimbs also will be dissected and one set will be snap frozen in liquid nitrogen while the other set will be mounted in OCT and frozen in isopentane cooled by liquid nitrogen. Cryosections will be used to evaluate disease activity and exercise-induced muscle injury by staining with: (a) hematoxylin and eosin to assess gross morphology, cellular infiltration, and necrosis, (b) anti-F4/80 to label macrophages, and (c) anti-IgG or IgM to label damaged muscle fibers.
Sample Type:Heart tissue

Treatment:

Treatment ID:TR000690
Treatment Summary:Studies will be performed in 12-16 week old male mdx mice, C57BL10 control mice, and nNOS-/- mice obtained from Jackson Laboratory. All protocols will be approved by the Penn State College of Medicine Institutional Animal Care and Use Committee. Treadmill Exercise: Mice will run on a horizontal treadmill (Columbus Instruments) to assess fatigue by a single bout of exercise beginning at 5 m/min for 5 min followed by 1 m/min increases every minute until exhaustion. Electric shocks will not be used to stimulate running due to adverse effects in mdx mice.
