mortality/aging
• mice begin to die between E10.5 and E12.5 with none present at birth
• mice begin to die between E10.5 and E12.5 with none present at birth

nervous system
• at E11.5, mice exhibit an increase in apoptotic cells in the brain compared to in wild-type mice
• at E9.5 to E11.5, the neural tube cell layer is thinner than in wild-type mice

cellular
• mouse embryonic fibroblasts exhibit clustered perinuclear mitochondria with extended tubules unlike in wild-type cells
• at E12.5, mitochondria are enlarged compared to in wild-type mice
• mouse embryonic fibroblasts exhibit elongated or swollen peroxisomes unlike in wild-type cells
• at E11.5, mice exhibit an increase in apoptotic cells in the brain compared to in wild-type mice
• slightly in mouse embryonic fibroblasts

embryo
• at E9.5 to E11.5
• at E9.5 to E11.5, the neural tube cell layer is thinner than in wild-type mice
