mortality/aging

embryo
increased embryonic tissue cell apoptosis ( J:111066 )
• at E9 (20 to 25 somite stage), embryos exhibit increased apoptosis compared with wild-type mice
decreased embryo size ( J:111066 )
• at E9 (20 to 21 somite stage), mice are smaller than normal due to fewer cells
decreased somite size ( J:111066 )
• slightly reduced size at E9

cellular
increased embryonic tissue cell apoptosis ( J:111066 )
• at E9 (20 to 25 somite stage), embryos exhibit increased apoptosis compared with wild-type mice
abnormal respiratory electron transport chain ( J:111066 )
• at 7 to 13 somite stages, mitochondria RC complex I activity is impaired

growth/size/body
decreased embryo size ( J:111066 )
• at E9 (20 to 21 somite stage), mice are smaller than normal due to fewer cells

nervous system
decreased brain size ( J:111066 )
• slightly reduced anterior brain at E9
