Collection:
| Collection ID: | CO000663 |
| 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. |

Treatment:
| Treatment ID: | TR000683 |
| 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. |
