mortality/aging

mortality/aging ( J:142586 )

N • mice exhibit normal survival during the first year of life

cellular

abnormal cell physiology ( J:142586 )

• mouse embryonic fibroblasts (MEFs) exhibit a 30% reduction in ATP levels compared to wild-type cells

• heart, kidney and liver ATP levels are more than 50% decreased compared to in wild-type mice

• MEFs are insensitive to rotenone or hydrogen peroxide induced ATP reduction unlike wild-type cells

• however, MEF sensitivity to a cytochrome c oxidase

abnormal cellular respiration ( J:142586 )

• complex I activity is decreased compared to in wild-type mice

• however, complex II activity is normal

• cellular respirations in mouse embryonic fibroblasts is decreased compared to in wild-type cells
