Common Names: BRAFF-V600E;     BRafCA;    
These Braf knock-in mice carry a genetically modified allele of human BRaf, BRafCA, which expresses normal BRaf prior to Cre-mediated recombination, but after which BRafVE is expressed. These mice may be useful in studies of human malignancies, as well as for studying the RAS-activated RAF/MEK/ERK mitogen-activated protein kinase signaling pathway and pleiotropic regulators of the aberrant cancer cell physiology.

Generation Definitions
Donating Investigator IMR Colony,   The Jackson Laboratory

Mice homozygous for the Cre-activated BRaf mutant allele (BRafCA) are viable and fertile. Mice express the transcript encoded by endogenous exons 1-14 and loxP-flanked human exons 15-18 (BRafCA) prior to Cre recombinase exposure. Homozygous mice have "normal" BRaf expression, and no abnormalities are reported for homozygous BRafCA mice. Following Cre-mediated excision of the floxed sequences (human BRAF exons 15-18 and polyA signal), the transcripts are subsequently generated using the downstream mutant exon 15 (modified with a V600E amino acid substitution associated with constitutively active BRAFV600E in human cancers) and the endogenous downstream exons 16-18. The resulting BRafVE transcripts are subject to normal patterns of alternate splicing and differential exon usage, and BRafVE expression is observed at physiological levels. To discriminate the expression of the various BRaf mRNAs in heterozygous mice, silent restriction enzyme polymorphisms were incorporated into the exon 15 sequences of BRafCA (BamHI) and BRafVE (XbaI).

For example, when crossed to a strain expressing tamoxifen-inducible Cre recombinase (see Stock No. 017585), this mutant mouse strain may be useful in studies of lung tumors.

The BRafCA mutant mice were created by Dr. Martin McMahon (University of California, San Francisco). The BRafCA targeted mutation was designed to replace the endogenous Braf exon 15 with (from 5' to 3') a loxP site, the cDNA sequence encoded by human BRAF exons 15-18 (with a silent BamHI restriction site polymorphism in exon 15), the mouse Braf polyA sequences, a PGK-neo cassette (with triple transcriptional stop and SV40 polyA signal), a second loxP site, and a mouse exon 15 sequence modified via site-directed mutagenesis to harbor both a V600E amino acid substitution (associated with the constitutively active BRAFV600E mutation in human cancers) and also a silent XbaI restriction site polymorphism. The targeting vector was microinjected into 129Sv/OLA embryonic stem (ES) cells, and correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric mice were bred with FVB/N mice to establish the colony. BRafCA mutant mice were subsequently maintained on a C57BL/6 congenic background.

  • mortality/aging
  • premature death
    • 7-8 weeks after adenoviral Cre intranasal administration to 6- to 8-week old mutants, treated animals are euthanized because they show labored breathing and general wasting   (MGI Ref ID J:121715)
  • tumorigenesis
  • increased lung tumor incidence
    • cellular origins of cancerous are ambiguous aslesions are Clara Cell antigen-negative, but majority of cells express Surfactant protein C as early as 2 weeks after Cre treatment (CCA and SP-C are both markers of alveolar type II pneumocytes)   (MGI Ref ID J:121715)
    • 4 weeks after Cre treatment, mice are treated for 28 days with a pharmacological inhibitor of MEK1/2 which prevents almost all tumor development, while vehicle-treated animals show numerous lung tumors   (MGI Ref ID J:121715)
    • increased lung adenocarcinoma incidence
      • only 2 mice (of 57) that develop adenomas show evidence of progression to adenocarcinoma; cells from these mice display nuclear enlargement, hyperchromasia, and contour irregularities   (MGI Ref ID J:121715)
    • increased lung adenoma incidence
      • 7 weeks after high dose Cre treatment, evidence of multiple adenomatous tumor formation is present in mouse lungs, while no tumors are detected in untreated mice after 6 months   (MGI Ref ID J:121715)
      • papillary adenomas are detected 6-8 weeks after lower dose adenoviral Cre treatment; lesions seem to increase in size and number   (MGI Ref ID J:121715)
      • lesions arise in alveolar ducts expanding outward and around broncioles   (MGI Ref ID J:121715)
      • at ~14 weeks, papillary adenomas undergo changes at periphery; cells change such that they have more cytoplasm and become eosinophilic   (MGI Ref ID J:121715)
      • after lower dose Cre treatement, adenomas do not grow beyond ~900 um in diameter   (MGI Ref ID J:121715)

  • lung epithelium hyperplasia
    • 4 weeks after Cre administration, lung epithelium hyperplasia is observed   (MGI Ref ID J:121715)

        involves: 129P2/OlaHsd
  • normal phenotype
  • no abnormal phenotype detected

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.
