cardiovascular system
• at P0, the aortic laminae is disrupted unlike in wild-type mice
• at P14, the elastic laminae is disrupted unlike in wild-type mice
• at 12 weeks, aorta are less distensible than in wild-type mice
• mice loss the internal elastic lamina in the ascending aorta unlike wild-type mice
• slightly elongated
• severe ascending aortic aneurysms
• the ascending aorta from the aortic root to just distal to the branching point of the brachiocephalic artery is dilated
• however, no aortic stenosis is observed
• at 12 weeks, aorta are less distensible and stiffer than in wild-type mice
