mortality/aging
• most mutant embryos look grossly abnormal and some of them start to die at E14.5
• mutant embryos appear to be phenotypically normal at E12.5
|
cardiovascular system
• delayed development of myofibrils resulting in scarce, disorganized myofibrils
• the myofibril structure and connections between the myocytes were disrupted
• sarcomere were collapsed at E14.5
|
• the filaments within a myofibril approaching the intercalated disk at different angles resulting in tapered, frayed and/or disorganized or disconnected morphology
|
• thin walls owing to the reduced size of the compact zone of the myocardium
|
hemorrhage
(
J:144625
)
• in E14.5 embryos
|
• of myocytes isolated from mutant embryo show reduced and abnormal contractility in culture
|
• the abolishment of actin arginylation was observed in alpha cardiac actin from E12.5 hearts
|
