homeostasis/metabolism
• mice subjected to pressure overload via transverse aortic constriction (TAC) exhibit left ventricular (LV) chamber dilation and cardiac dysfunction 4 weeks after surgery
• the LV weight-to-tibia length ratio is increased to a greater extent than in wild-type mice after TAC
• TAC-operated mice exhibit more severe cardiac hypertrophy and larger fibrosis fractions and cross-sectional areas of cardiomyocytes than TAC-operated wild-type mice
|
• cytosolic ATP concentration in TAC-operated hearts is lower
|
• TAC-operated mice exhibit lower levels of mitophagy
|
cardiovascular system
• cardiomyocyte cross-sectional area is larger in the TAC-operated mice compared to TAC-operated wild-type mice
|
• the population of mitochondria with longer lengths and smaller mitochondrial areas is increased in TAC-operated hearts
