cellular
decreased thymocyte apoptosis ( J:80311 )
• radiation-induced apoptosis in the thymus is increased as compared to homozygous Trp53tm1Tyj mice, but is decreased as compared to wild-type, and is similar to heterozygous Trp53tm1Tyj mice

endocrine/exocrine glands
decreased thymocyte apoptosis ( J:80311 )
• radiation-induced apoptosis in the thymus is increased as compared to homozygous Trp53tm1Tyj mice, but is decreased as compared to wild-type, and is similar to heterozygous Trp53tm1Tyj mice

hematopoietic system
decreased thymocyte apoptosis ( J:80311 )
• radiation-induced apoptosis in the thymus is increased as compared to homozygous Trp53tm1Tyj mice, but is decreased as compared to wild-type, and is similar to heterozygous Trp53tm1Tyj mice

immune system
decreased thymocyte apoptosis ( J:80311 )
• radiation-induced apoptosis in the thymus is increased as compared to homozygous Trp53tm1Tyj mice, but is decreased as compared to wild-type, and is similar to heterozygous Trp53tm1Tyj mice

mortality/aging
premature death ( J:80311 )
• average lifespan is 9.5 months
• mice live longer than homozygous Trp53tm1Tyj mice (4.5 months)
• but, not as long as heterozygous Trp53tm1Tyj mice (14 months)

neoplasm
decreased tumor incidence ( J:80311 )
• 17% of mice exhibit tumors following spontaneous death as compared to 47% of wild-type mice
decreased incidence of tumors by chemical induction ( J:80311 )
• mice develop fewer 3MC-induced fibrosarcomas as compared to wild-type; 8/12 mice are tumor free, 11/12 wild-type mice develop fibrosarcomas
• mice develop fewer BBN-induced urinary bladder carcinomas as compared to wild-type; tumors that develop are monofocal rather than multifiocal and develop later

immune system
increased thymocyte apoptosis ( J:80311 )
• increased induction of apoptosis in thymus following whole body irradiation
