behavior/neurological

behavior/neurological phenotype ( J:154709 )

N	• mice exhibit normal passive avoidance and active avoidance

abnormal learning/memory/conditioning ( J:154709 )

• 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

abnormal spatial learning ( J:154709 )

• 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

cardiovascular system phenotype ( J:211441 )

N	• whether or not infused with angiotensin II, mice exhibit normal heart rate

abnormal artery morphology ( J:211441 )

• disorganized extracellular matrix collagen fibers with reduced collagen I protein level in the carotid arteries of mice treated with angiotensin II

• at baseline

abnormal blood vessel physiology ( J:211441 )

• 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

decreased vasodilation ( J:211441 )

• following angiotensin II infusion, arteries are more distensible than in wild-type mice

• however, doxycycline treatment prevents reduction lumen dilation
