mortality/aging
• mice begin to die before E10.5 and are dead by E11.5
|
cardiovascular system
• mice exhibit reduced vascular complexity particularly in the head capillary plexus and branchial arches compared with wild-type mice
|
• mice exhibit reduced vascular complexity particularly in the head capillary plexus and branchial arches compared with wild-type mice
|
• mice exhibit reduced number of myocardial cells compared with wild-type mice without an increase in apoptosis in the heart
|
• increased in thickness at E10.5
|
• the septum of the atrium of the E10.5 mutant mice has not developed
|
• thin
|
• at E10.5, mice exhibit dilated heart unlike wild-type mice
• however, heart development between E8.5 and E9.5 and heart looping are normal
|
embryo
• branchial arches remain at E11.5 unlike in wild-type mice
|
• at E9.5
|
nervous system
• at E9.5, mice exhibit apoptosis in the neural tube unlike in wild-type mice
• at E10.5, apoptosis in the neural tube is further increased unlike in wild-type mice
|
• at E10.5, forebrains are smaller than in wild-type mice
• at E11.5, the front brain is undifferentiated unlike in wild-type mice
|
growth/size/body
• at E9.5
|
homeostasis/metabolism
• mice exhibit increased squalene and lanosterol and decreased cholestenol, lathosterol, and desmosterol levels compared with wild-type mice
• however, total cholesterol levels are normal
|
craniofacial
• branchial arches remain at E11.5 unlike in wild-type mice
|
muscle
• mice exhibit reduced number of myocardial cells compared with wild-type mice without an increase in apoptosis in the heart
|
• increased in thickness at E10.5
|
cellular
• at E9.5, mice exhibit apoptosis in the neural tube unlike in wild-type mice
• at E10.5, apoptosis in the neural tube is further increased unlike in wild-type mice
