Tspyl2tm1Sich/Tspyl2tm1Sich
Genetic
Background
involves: 129S/SvEv
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Tspyl2tm1Sich mutation (0 available); any Tspyl2 mutation (7 available)
phenotype observed in females
phenotype observed in males
N normal phenotype
cellular
N
• cultured ES cells, MEFs and thymocytes all show normal proliferation and senescence
• ionizing radiation induce cell death of cultured thymocytes and MEFs is similar to wild-type cells
• following exposure to 10 Gy ionizing radiation MEFs return to S phase more rapidly indicating a defect in maintenance of the G1 checkpoint
• however, checkpoint initiation is similar to wild-type cells and in the absence of treatment no defects in cell cycle are detected

mortality/aging
N
• normal lifespan

nervous system
N
• no decrease in proliferation of neuronal precursors in the dentate gyrus of the hippocampus or subependyma surrounding the lateral ventricles is detected
• brain morphology is normal

reproductive system
N
• despite high expression of the gene in wild-type gonads, mice are fertile

neoplasm
N
• no spontaneous tumor formation
