renal/urinary system
• following unilateral ureter obstruction, mice exhibit increased kidney size, distended renal tissue, unclear border between the outer and inner medulla, severe hydronephrosis, and smaller medulla to cortex ratio compared with similarly treated wild-type mice
• following unilateral ureter obstruction compared with similarly treated wild-type mice
• more severe following unilateral ureter obstruction compared to in similarly treated wild-type mice

homeostasis/metabolism
• following unilateral ureter obstruction, mice exhibit increased kidney size, distended renal tissue, unclear border between the outer and inner medulla, severe hydronephrosis, and smaller medulla to cortex ratio compared with similarly treated wild-type mice

cardiovascular system
N
• mice exhibit normal blood pressure and heart rate
• mutants exhibit adverse aortic remodeling after 2 weeks of angiotensin II infusion compared to wild-type mice, showing disorganized and disrupted elastin fibers and disorganized collagen structures, especially in the abdominal aorta
• angiotensin II infused mutants exhibit disrupted medial elastic lamellae and fibrillar structures in the abdominal aortic walls
• mutants treated with angiotensin II exhibit an increase in macrophage infiltration in the abdominal aorta and disrupted medial elastic lamellae and fibrillar structures in the abdominal aortic walls
• 60% of mutants develop abdominal aortic aneurysm after 4 weeks of angiotensin II infusion unlike wild-type mice, showing greater than 50% aortic dilation in the suprarenal region
• treatment with a broad spectrum protease inhibitor, PD166793, during the course of angiotensin II infusion blocks abdominal aortic aneurysm development
• the aortic systolic expansion index, a measure of aortic elasticity and recoil property during systole and diastole is suppressed in the aneurysmal aorta of angiotensin II infused mutants
• mutants treated with angiotensin II exhibit an increase in macrophage infiltration in the abdominal aorta

immune system
• mutants treated with angiotensin II exhibit an increase in macrophage infiltration in the abdominal aorta

mortality/aging
• survival is compromised after angiotensin II infusion due to aortic rupture, with mice showing 80-85% survival 28 days after infusion

growth/size/body
• following unilateral ureter obstruction compared with similarly treated wild-type mice

behavior/neurological
N
• mice exhibit normal passive avoidance and active avoidance
• after several days in an open-field, mice fail to become accustomed to their environment, as determined by maintenance of novel environment locomotion and rearing levels, unlike similarly treated wild-type mice
• in a water maze test with invisible platform, mice exhibit reduced memory acquisition on day 2 compared with wild-type mice
• deficit in memory acquisition in a water maze test with invisible platform lessens with time
• however, by day 5 memory acquisition in a water maze with invisible platform is normal and performance in a water maze test with visible platform is normal

cardiovascular system
N
• whether or not infused with angiotensin II, mice exhibit normal heart rate
• disorganized extracellular matrix collagen fibers with reduced collagen I protein level in the carotid arteries of mice treated with angiotensin II
• however, doxycycline treatment prevents aberrant arterial extracellular matrix degradation
• disorganized and interrupted elastin fibers and lower elastin protein content in carotid arteries of mice treated with angiotensin II
• following angiotensin II infusion, mice fail to exhibit an increase in blood pressure as observed in wild-type mice
• following angiotensin II infusion, mesenteric arteries exhibit a reduced increase in media to lumen ratio with reduced medial thickness and increased lumen diameter compared with wild-type mice
• however, doxycycline treatment prevents reduction in media to lumen ratio
• following angiotensin II infusion, arteries are more distensible than in wild-type mice
• however, doxycycline treatment prevents reduction lumen dilation
