hm1

• Allelic Composition: Uimc1^tm1.2Amj/Uimc1^tm1.2Amj
• Genetic Background: involves: BALB/cJ * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

increased susceptibility to xenobiotic induced morbidity/mortality ( J:191827 )

• when exposed to DMBA weekly for 4 weeks tumor free survival time is reduced compared to wild-type controls

neoplasm

increased incidence of tumors by chemical induction ( J:191827 )

• when exposed to DMBA weekly for 4 weeks 40% of mice develop mammary tumors compared to only 5% of wild-type controls

• however, no difference in the induction of lymphomas or ovarian carcinomas by DMBA is detected

increased lymphoma incidence ( J:191827 )

• by 20 months of age, 52% of mice develop either thymic or splenic lymphomas

• occasionally, lymphomas infiltrate nonlymphoid tissues

increased T cell derived lymphoma incidence ( J:191827 )

increased B cell derived lymphoma incidence ( J:191827 )

increased incidence of tumors by ionizing radiation induction ( J:191827 )

• after exposure to 6 Gy ionizing radiation about 18% (4 of 22) develop thymic lymphomas compared to only 4.7% (1 of 21) wild-type mice

homeostasis/metabolism

increased susceptibility to xenobiotic induced morbidity/mortality ( J:191827 )

• when exposed to DMBA weekly for 4 weeks tumor free survival time is reduced compared to wild-type controls

increased incidence of tumors by chemical induction ( J:191827 )

• when exposed to DMBA weekly for 4 weeks 40% of mice develop mammary tumors compared to only 5% of wild-type controls

• however, no difference in the induction of lymphomas or ovarian carcinomas by DMBA is detected

cellular

abnormal cell cycle checkpoint function ( J:191827 )

• prolonged G2-M arrest in response to ionizing irradiation

decreased fibroblast proliferation ( J:191827 )

• the doubling time of MEFs increases more rapidly upon passing compared to wild-type MEFs and cultures contain fewer proliferating cells

early cellular replicative senescence ( J:191827 )

• by passage 3 MEF cultures contain more giant non-dividing senescent cells

endocrine/exocrine glands

increased T cell derived lymphoma incidence ( J:191827 )
