• despite altered response to Ras retroviral infection, mouse embryonic fibroblasts (MEFs) can enter replicative senescence and reach immortality at rates indistinguishable from wild-type MEFs and are as sensitive to apoptosis in thymocytes induced by DNA damage or other stimuli as wild-type MEFs
|
• mouse embryonic fibroblast cells (MEFs) are insensitive to infection with a retroviral Ras exhibiting an increase in proliferation relative to controls and decreased senescence unlike similarly treated wild-type MEFs
|
• very few cells exhibit senescence when infection with a retroviral Ras unlike similarly treated wild-type MEFs
