N normal phenotype
cardiovascular system
decreased cardiac muscle contractility ( J:154303 )
• mice exhibit lower end-systolic pressure volume relationship compared with wild-type mice
abnormal myocardial fiber physiology ( J:154303 )
• cardiomyocyte sarcomeric function is decreased with impaired velocity of contraction and relaxation compared to in wild-type mice
• however, intracellular calcium is unchanged

homeostasis/metabolism
impaired exercise endurance ( J:154303 )
• mice exhibit decreased exercise endurance compared with wild-type mice
decreased oxygen consumption ( J:154303 )
• mice exhibit reduced maximal oxygen consumption compared with wild-type mice

muscle
