This targeted mutation of MLX interacting protein-like (Mlxlpl) gene displays increased glucose and insulin levels, decreased free fatty acids, reduced epididymal and brown fat weight, and reductions in liver glycolysis and lipogenic enzymes. This mutant mouse strain may be useful in studies of lipogenesis and glucose metabolism.

Description
Mice that are homozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Mutant mice exhibit increased glucose and insulin levels, decreased free fatty acids, reduced epididymal and brown fat weight, and reductions in liver glycolysis and lipogenic enzymes. Mice fed diets high in sucrose or fructose died within one week most likely as a result of inhibited glycolysis. On a high starch diet, mice developed moderate insulin resistance and increased liver weight. This mutant mouse strain may be useful in studies of lipogenesis and glucose metabolism.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exons 12 through 14. The construct was electroporated into 129S6/SvEvTac derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were crossed to C57BL/6J for 25 generations. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.

SNP (single nucleotide polymorphism) analysis performed by The Jackson Laboratory revealed that the Donating Investigator used C57BL/6N (4 of 5 markers segregating) in the development of the strain.

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.
