mortality/aging

increased susceptibility to induced morbidity/mortality ( J:152458 )

• following carotid artery ligation, 50% of mice die compared to less than 10% of similarly treated wild-type mice

cardiovascular system

abnormal blood vessel morphology ( J:152458 )

• mice exhibit thicker extracellular matrix surrounding vessels compared with wild-type mice

abnormal vascular smooth muscle morphology ( J:152458 )

• vascular smooth muscle cells exhibit a reduction in the number and prominence of stress fibers compared with wild-type cells

vascular smooth muscle hypotrophy ( J:152458 )

• mice exhibit a reduction in vascular smooth muscle wall thickness and in the width of vascular smooth muscle cells in the aorta and other arteries compared with wild-type mice

abnormal vascular wound healing ( J:152458 )

• following carotid artery ligation, mice fail to exhibit neointimal thickening, exhibit reduced medial layer thickness, and develop neurological abnormalities associated with left hemisphere necrosis prior to death in 50% of mice compared with similarly treated wild-type mice

behavior/neurological

impaired coordination ( J:152458 )

• prior to death induced by carotid artery ligation

circling ( J:152458 )

• prior to death induced by carotid artery ligation

seizures ( J:152458 )

• prior to death induced by carotid artery ligation

homeostasis/metabolism

abnormal vascular wound healing ( J:152458 )
