cardiovascular system
• cardiomyocytes of older mutants (9 months of age) exhibit increased length but not width
• myocardium of older mutants (9 months of age) shows disorganized myofibrils with increased nonmyofibrillar space filled with swelled mitochondria
• develop eccentric cardiac hypertrophy (normal left ventricle wall thickness and increased left chamber dimension) upon stimulation with angiotensin II or pressure overload by transverse aortic constriction, exhibiting an increase in heart/body weight ratios and elevated markers of cardiac hypertrophy
• older mutants develop spontaneous cardiac chamber dilation
• develop multifocal interstitial fibrosis upon stimulation with angiotensin II

mortality/aging
• mutant embryos are progressively lost starting at E13.5 with only 3% of pups at birth having the conditional null genotype

cardiovascular system
• endothelial cells lining small capillaries have pyknotic and karyorrhetic changes and many are rounded, detached, and sloughing off into the lumen
• apoptotic and necrotic endothelial cells are seen
• many capillaries with abnormal endothelial cells are collapsed
• arterial canals and canal branches lack fetal red blood cells and some of the vessels appear collapsed; however the heart appears normal

• fewer branched vessels and a marked decrease in sprouting angiogenesis are seen in the yolk sac
• at E13.5, multifocal, scattered, and variably sized hemorrhages are seen and at E14.5 these are large and superficial
