cellular
abnormal cell cycle ( J:139510 )
• mouse embryonic fibroblasts exhibit delayed entry into S phase compared to wild-type cells
decreased fibroblast proliferation ( J:139510 )
• mouse embryonic fibroblasts exhibit reduced proliferation and reach plateau sooner compared to wild-type cells
early cellular replicative senescence ( J:139510 )
• mouse embryonic fibroblasts cease replicating sooner than in wild-type cells
abnormal DNA repair ( J:139510 )
• mouse embryonic fibroblasts exhibit increased accumulation of DNA damage following treatment with gamma radiation compared to in similarly treated wild-type cells
• however, the DNA of mouse embryonic fibroblasts exhibit normal sensitivity to DNA damage

growth/size/body
decreased body size ( J:139510 )
• at birth

respiratory system
abnormal pulmonary alveolus morphology ( J:139510 )
• mice die within hours of birth probably due to alveolar defects

homeostasis/metabolism
abnormal DNA repair ( J:139510 )
• mouse embryonic fibroblasts exhibit increased accumulation of DNA damage following treatment with gamma radiation compared to in similarly treated wild-type cells
• however, the DNA of mouse embryonic fibroblasts exhibit normal sensitivity to DNA damage
