Overview

Also Known As:p53 KO

Trp53 knockout mutant mice develop tumors at three to six months of age. They are suitable for use in applications related to the study of familial breast cancers such as Li-Fraumeni syndrome as well as research of lung, brain and bone tumors, lymphoma and leukemia, and other rare cancers.

Detailed Description

A neomycin cassette replaces exons 2-6 (including the start codon) of the transformation related protein 53 gene (Trp53). Mice homozygous for the mutation show no visible phenotype but most develop tumors (principally lymphomas and sarcomas) at three to six months of age. Heterozygous mice develop tumors at about 10 months of age. These mice model some of the features of human Li-Fraumeni syndrome, a form of familial breast cancer with mutations in TRP53. Homozygous mice may produce a litter before succumbing to tumors.

For the C57BL/6-J congenic Trp53^tm1Tyj mouse line (Stock No. 002101), it is the experience of The Jackson Laboratory that homozygous males have expected Mendelian survival rates at wean age, but homozygous females have significantly reduced survival by wean age. Specifically, breeding heterozygous females to heterozygous males results in only ~3.5% homozygous females by wean age (expected Mendelian 12.5%). Additionally, breeding heterozygous females to homozygous males results in only ~6.8% homozygous females by wean age (expected Mendelian 25%).

Development

The Trp53^tm1Tyj mutant strain was developed in the laboratory of Dr. Tyler Jacks at the Center for Cancer Research at the Massachusetts Institute of Technology. The 129-derived D3 ES cell line was used. The C57BL/6J strain was produced by backcrossing the Trp53^tm1Tyj mutation at least five times to C57BL/6J inbred mice.

A 48 SNP (single nucleotide polymorphism) panel analysis, with 43 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. One of the 43 markers, on Chromosome 8, was segregating with 129.

Trp53^tm1Tyj

Allele Symbol: Trp53^tm1Tyj

Allele Name	targeted mutation 1, Tyler Jacks
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	p53-; p53^delta; p53^null; p53KO; Trp53-; Trp53^KO
Gene Symbol and Name	Trp53, transformation related protein 53
Gene Synonym(s)
Site of Expression	Normal Trp53 expression is widespread.
Strain of Origin	129S2/SvPas
Chromosome	11
General Note	This mutant allele was produced by a targeted neo insertion into the Trp53 locus. Homozygotes show no visible phenotype but develop tumors at 3-6 months of age. Heterozygotes develop tumors at 10 months of age. These mice model some of the features of human Li-Fraumeni syndrome (OMIM 151623), a form of familial breast cancer with mutations in TRP53 (J:16022)(J:16023) A specific human mutation found in hepatocellular carcinomas caused by hepatitis B infection or by aflatoxin exposure has been created in a mouse model, resulting in a similar gene product (J:27363).
Molecular Note	A neomycin cassette replaced 40% of the coding sequences beginning with exon 2 (upstream of the translation start site) and extending into exon 6.

Breeding Considerations

This strain is a challenging breeder.

This Trp53^tm1Tyj strain is maintained by mating heterozygous mice together or by mating heterozygous females with homozygous males.

For the C57BL/6-J congenic Trp53^tm1Tyj mouse line (Stock No. 002101), it is the experience of The Jackson Laboratory that homozygous males have expected Mendelian survival rates at wean age, but homozygous females have significantly reduced survival by wean age. Specifically, breeding heterozygous females to heterozygous males results in only ~3.5% homozygous females by wean age (expected Mendelian 12.5%). Additionally, breeding heterozygous females to homozygous males results in only ~6.8% homozygous females by wean age (expected Mendelian 25%).

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
