|
muscle
|
• at birth, mice completely lack extraocular muscles or only have residual myofibers unlike in wild-type mice
|
|
• by E11.5, the extraocular muscle anlage fails to pattern and begins to atrophy unlike in wild-type mice
• extraocular muscle anlagen exhibits a 5- to 6-fold increase in apoptotic cells compared to in wild-type mice
|
embryo
|
• at E11.5, somatic muscle progenitor cells exhibit a temporary pause in development but do not apoptose
• however, somite fate is rescued thereafter by Myod1 expression
|
vision/eye
|
• at birth, mice completely lack extraocular muscles or only have residual myofibers unlike in wild-type mice
|
|
• by E11.5, the extraocular muscle anlage fails to pattern and begins to atrophy unlike in wild-type mice
• extraocular muscle anlagen exhibits a 5- to 6-fold increase in apoptotic cells compared to in wild-type mice
|
mortality/aging
|
• double homozygous mutants display postnatal lethality
|
muscle
|
• no skeletal myogenesis is seen at any developmental stage
|
|
• mutants lack skeletal muscle throughout the body including the head
