Abstract
As one of the largest collections of characterized mouse strains available, The Jackson Laboratory Repository serves the scientific community as a resource to archive and distribute mouse models. Among the hundreds of new strains acquired or developed annually are a transgenic model for prostate hyperplasia that progresses to adenoma/adenocarcinoma, a transgenic model of large B cell lymphoma similar to tumors seen in patients with SLE and Sjogren's syndrome; and a targeted mutation strain of Lats1 (large tumor suppressor) that develops soft tissue sarcomas, ovarian stromal cell tumors and increased sensitivity to carcinogens. Conditional (floxed) strains that are useful in generating tissue-specific mutants have been recently added to the Repository and include mutations of Perp (TP53 apoptosis effector), Msh2 (mutS homolog 2, E. coli), and Irf8 (interferon regulatory factor 8). A transgenic strain that expresses Cre recombinase specifically in the large intestine has applications in colon cancer research. A combination mutant strain (containing targeted mutations of Vhl, von Hippel-Lindau tumor suppressor, and Pten, phosphatase and tensin homolog, and a transgene with Cre recombinase expression driven by Cdh16, cadherin 16) is a model for benign mixed adenosquamous genital tract tumors resembling clear cell cystadenomas observed in patients with Von Hippel-Lindau syndrome. The TEL-AML1 (Etv6-RUNX1, t12;21) translocation/fusion protein associated with childhood acute lymphoblastic leukemia is conditionally expressed by a targeted mutation strain. For transplantation research, a number of “humanized” mouse strains are available. These typically are immune compromised lines and/or lines that provide continuous circulation of human growth factors supporting a platform for a humanized microenvironment. A number of new research tool strains have been added to the Repository, including a fluorescent reporter for carcinoma metastasis, the Cre reporter R26R-Confetti strain which allows individual cell labeling with nuclear-localized membrane-targeted or cytoplasmic fluorescent proteins, and transgenic strains expressing the KikGR flurorescent protein which changes color from green to red upon activation. The Repository maintains a searchable on-line resource (www.jax.org) for each strain. Researchers can submit their strains by using the on-line form available at The Jackson Laboratory website: www.jax.org/donate-a-mouse.
