Friedreich’s Ataxia (FA) is a progressive, autosomal recessive, neurodegenerative disease. Its onset, typically around puberty, is marked by a rapid progression, with most patients relying on a wheelchair by their late 20s. FA is caused by a trinucleotide (GAA) repeat expansion mutation within intron 1 of the frataxin gene. The severity of the disease directly correlates to the size of the expansion.
While it cannot be stopped completely, genetic drift and the impact on scientific discovery can be minimized through careful and thoughtful colony management practices. Download our new whitepaper to learn more.
Acute myeloid leukemia is a complex hematological malignancy with high molecular heterogeneity. JAX offers ten AML patient-derived xenograft (PDX) models with varying mutational profiles and treatment histories. These models are available for analyzing the effectiveness of potential new drugs–alone or in combination–to treat AML. These PDX models (Townsend et al.) have been engrafted in the highly immunodeficient NSG-SGM3 (stock #013062), the mouse strain that most effectively engrafts human myeloid leukemia.
To support a collaboration between Dr. Cat Lutz of The Jackson Laboratory and the Friedrich’s Ataxia Research Alliance, our Model Generation Services (MGS) team undertook a project to create a conditional knockout allele of the Frataxin (Fxn) gene using the Cre-loxP Recombination System.
Mice are used extensively in aging research due to their genetic and physiological similarity to humans. Aging studies are—by necessity—lengthy, resource intensive, and require advance planning. The Jackson Laboratory now offers study-ready cohorts of male and female C57BL/6J mice up to 78 weeks of age. This article is intended to support investigators who may be new users of this resource and more experienced researchers who may be seeking a quick and useful summary. We will review special considerations for maximizing the translational value of data collected from aged mice and highlight resources for identifying and implementing best practices.
Genome editing with CRISPR/Cas9 enables the generation of new mouse models with unprecedented speed and simplicity. The Jackson Laboratory was an early adopter of CRISPR/Cas9 technology for mouse model development, and in this brief guide we describe the technology and lessons learned to generate knockouts and knockins in more than a dozen different genetic backgrounds.
NSG™ and NSG™-SGM3 mice engrafted with allogeneic human tumors represent a valuable preclinical testing platform for immuno-oncology. Here we employ four 14-color flow cytometry panels to perform a comprehensive and detailed analysis of the entire immune system. Our results indicate that the triple transgenic NSG™-SGM3 mice exhibit a more completely humanized immune system as compared to NSG™ mice, with specific improvements in the distribution of T-cell subsets and overall representation of the myeloid lineage.
Humanized NSG™ mice are used by researchers and drug discovery scientists as powerful tools to study hematopoiesis, inflammatory disease and viral host-pathogen interactions. These mouse models are accelerating the development of novel therapies in HIV infection and oncology.

The JAX ActionSeq™ test is a targeted panel of 212 cancer related genes analyzed using next-generation sequencing. The panel assesses all identified functional variants for clinical relevance, based on associations in the biomedical literature with response or resistance to FDA-approved targeted therapies.
Every patient is unique. So is every patient’s tumor. This one pager explains how advances in high-throughput molecular diagnostics now allow detection of the genetic alterations that are specific to an individual patient’s tumor. By identifying the oncogenic drivers, therapeutic options can be matched to the tumor’s biology.
NSG™ mouse model variants are the most highly immunodeficient mice and the models of choice for cancer xenograft modeling, stem cell biology, humanized mice, and infectious disease research. Download this guide to compare NSG™ mouse model strains.
Designing and validating models for the study of neurological diseases presents a unique set of challenges. Experts understand that modeling neurodegenerative diseases may be arduous and can present challenges that need to be addressed when used for preclinical studies (Lutz & Osborne, 2013). In this whitepaper, we will review best practices for using models for neuromuscular diseases to identify molecular targets and to evaluate the efficacy of potential therapeutics.
Type 1 diabetes is a disease characterized by autoimmune destruction of the insulin producing pancreatic beta cells by autoreactive, pathogenic T cells. B lymphocytes play a key role in this process by acting as antigen presenting cells for these T cells. Dr. David Serreze of The Jackson Laboratory was interested in testing the hypothesis that the Aicda gene, which is required for class switch recombination/somatic hypermutation in B lymphocytes, is important in the development of diabetes.
