• Background Sensitivity: on CD-1 background, 7% of mutants die and/or are resorbed on E16.5 while on a C57BL/6 background, 22% of mutants die on E16.5
|
|
• Background Sensitivity: 9% of young mutants aged 6-13 weeks exhibit rhabdomyosarcoma on a CD-1 background
• Background Sensitivity: incidence of rhabdomyosarcoma is lower on the C57BL/6 background than on the CD-1 background, with only 1 of 53 showing this phenotype
• tumors generally involve the skeletal muscle of the rear thigh, lumbar region or abdominal wall
• tumors are unencapsulated and neoplastic cells invade the adjacent muscle and fat
|
|
• mice exhibit a mandibular cyst lined by squamous epithelium adjacent to a tooth root
|
|
• 2 of 44 mutants on a CD-1 background at E16.5 exhibit failure of anterior neural tube closure
|
|
• mice exhibit a mandibular cyst lined by squamous epithelium adjacent to a tooth root
|
|
• dermal cyst is lined with keratinizing epithelium and filled with hair shafts
|
|
• generalized overgrowth by 20% at 6-8 weeks of age
|
|
• 12% increase in body size at E16.5
|
|
• 2 of 44 mutants on a CD-1 background at E16.5 exhibit failure of anterior neural tube closure
|
|
• develop medulloblastomas
|
|
• 2 of 44 mutants on a CD-1 background at E16.5 exhibit failure of anterior neural tube closure leading to exencephaly
|
|
• mice exhibit a mandibular cyst lined by squamous epithelium adjacent to a tooth root
|
|
• rib anomalies
|
|
• missing rib
|
|
• Background Sensitivity: 9% of young mutants aged 6-13 weeks exhibit rhabdomyosarcoma on a CD-1 background
• Background Sensitivity: incidence of rhabdomyosarcoma is lower on the C57BL/6 background than on the CD-1 background, with only 1 of 53 showing this phenotype
• tumors generally involve the skeletal muscle of the rear thigh, lumbar region or abdominal wall
• tumors are unencapsulated and neoplastic cells invade the adjacent muscle and fat
|
|
• develop medulloblastomas
|
|
• embryos on the CD-1 background exhibit increased sensitivity to ionizing radiation than wild-type embryos, with a 4.1 times higher frequency of defects such as micropthalmia, anopthalmia, exencephaly, polydactyly or syndactyly
|
|
• dermal cyst is lined with keratinizing epithelium and filled with hair shafts

• newborns irradiated with X-rays develop increased incidence of medulloblastoma and exhibit a higher mortality compared to irradiated wild-type mice or unirradiated heterozygotes, such that by 38 weeks of age, 33% of wild-type die versus 90% of mutants
• irradiated mutants die predominately from medulloblastomas while wild-type mice die from thymic lymphomas
|
|
• spontaneous medulloblastoma incidence of 7.7%
(J:79666)
• newborns, but not adults, show increased susceptibility to medulloblastoma formation following X-ray irradiation, with 74.5% incidence in mutants compared to 19.2% incidence in unirradiated mutants and 30.4% incidence in irradiated wild-type mice
(J:79666)
• tumors show loss of the wild-type allele
(J:79666)
• susceptibility of radiation-induced medulloblastoma development is increased in females that are ovariectomized compared to non-ovariectomized females
(J:165388)
• estrogen replacement reduces this susceptibility back to levels seen in non-ovariectomized females
(J:165388)
|
|
