Overview

Also Known As:Adam15 E>A

The Adam15 E>A knockin mice carry a point mutation that inactivates the catalytically active zinc-dependent metalloprotease domain resulting reduced tumor development in a heterotopic tumor injection model.

Detailed Description

Adam15 or a disintegrin and metallopeptidase domain 15 (metargidin) encodes a membrane-anchored metalloproteinase. Members of the ADAM family are involved in pathological neovascularization and are associated with cancer, atherosclerosis, RA and osteoarthritis. The Adam15 E>A knockin allele inactivates the catalytically active zinc-dependent metalloprotease domain. Mice homozygous for the mutation are viable and fertile. When injected heterotopically with melanoma cells, Adam15 E>A mice form fewer and smaller tumors than wild-type mice. This strain may be useful for studying the catalytic domain in Adam15 and tumor development.

Development

The targeting vector was designed to insert an E>A point mutation into exon 11 by site-directed mutagenesis. An FRT-flanked neomycin cassette was inserted downstream of exon 11. The mutation results in an A to C change at nucleotide 6829 altering the corresponding amino acid from glutamate to alanine.

The construct was electroporated into unspecified embryonic stem (ES) cells derived from 129P2/OlaHsd mice. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6J females. Mice were crossed to B6;SJL-Tg(ACTFLPe)9205Dym/J to remove the neomycin cassette. Heterozygous mice were mated and offspring crossed to mixed C57BL/6 and 129/SvJ mice for several generations. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.

Molecular Note	The targeting vector is designed to insert a E to A point mutation into the catalytic domain (exon 11) by site-directed mutagenesis. An FRT-flanked neomycin cassette is inserted downstream of exon 11. The mutation results in a A to C change at nucleotide 6829 altering the corresponding amino acid from glutamate to alanine. Flp-mediated recombination removed the FRT-flanked neo cassette.

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.
