Abstract
Abstract Genetically defined mice are a cornerstone of cancer research. The Jackson Laboratory (JAX) offers more than 13,500 unique mouse lines to the scientific community, many useful in advancing cancer research. Available are mouse models for specific cancers, xenograft recipients, immunodeficient platforms for PDX studies and multi-purpose tool strains having CRISPR/Cas9 expression, conditional/inducible expression (Cre-lox, FLP-frt, Tet-On/-Off), optogenetic function and calcium-sensing technologies. This poster will highlight some recently added models, more than 150 of which have cancer research applications. The portfolio of strains useful for transplantation/engraftment and “humanized” mouse research continues to expand and complement the NSG (NOD scid IL2rγc-/-) model as ideal tools for engraftment with a wide range of malignant or non-malignant human or mouse tissues. Fluorescent protein-expressing strains include the Traffic Light Reporter models for tracking of DNA repair pathways and the Gene Editing Reporter models for detection of homology directed repair (HDR) or non-homologous end joining (NHEJ) repair events. As a tool for gene targeting, the RosaBxb-GT/GA mice are designed to allow insertion of ~40kb of desired DNA sequence into the Gt(ROSA)26Sor locus. In addition to safeguarding each strain by cryopreservation, JAX has a comprehensive genetic quality control program that confirms mutation identity and genetic background, and screens for unwanted alleles (such as stray GFP, Cre, neo, etc.). Search the comprehensive collection of innovative mouse models using our improved JAX Mouse Search site (mice.jax.org). This resource includes models created by many generous donating institutions. Researchers are encouraged to donate their mouse lines via a very short Strain Submission form (jax.org/donate-a-mouse). Please also visit the JAX Oncology webpage for cancer research related strains and resources (jax.org/jax-mice-and-services/solutions-by-therapeutic-area/oncology). JAX is supported by the NIH, The Howard Hughes Medical Institute and other private charitable foundations.
