| The mouse Myh6 (myosin, heavy polypeptide 6, cardiac muscle, alpha) cardiac muscle-specific promoter drives expression of FLAG-tagged Ppara (peroxisome proliferator activated receptor alpha) in this transgenic strain. Hearts of hemizygotes depend on fatty acid for the generation of energy to a significantly greater extent than do hearts of non-transgenic mice and have a substrate utilization profile similar to that of the diabetic heart. Cardiac dysfunction is exhibited by 4-5 months of age with no imposed stress, or after being placed on a high fat diet. This strain may be useful in studies of metabolic alterations associated with diabetic cardiomyopathy and other forms of lipotoxic cardiomyopathy. This is the "low expressor" line. | |||||||||||||||||||

Generation DefinitionsDonating Investigator Daniel Kelly, Burnham Institute for Medical Research Description
The mouse Myh6 (myosin, heavy polypeptide 6, cardiac muscle, alpha) cardiac muscle-specific promoter drives expression of FLAG-tagged Ppara (peroxisome proliferator activated receptor alpha) in this transgenic strain. Expression of Ppara is increased approximately 15-fold as compared to wildtype in this line (404-4). Hearts of hemizygotes depend on fatty acid for the generation of energy to a significantly greater extent than do hearts of non-transgenic mice and have a substrate utilization profile similar to that of the diabetic heart. Cardiac dysfunction is exhibited by 4-5 months of age with no imposed stress, or after being placed on a high fat diet. This strain may be useful in studies of metabolic alterations associated with diabetic cardiomyopathy and other forms of lipotoxic cardiomyopathy.Development
The mouse Myh6 (myosin, heavy polypeptide 6, cardiac muscle, alpha) promoter drives expression of mouse Ppara (peroxisome proliferator activated receptor alpha) cDNA carrying a C-terminal FLAG tag. The transgenic construct was introduced to B6CBAF1 hybrid embryos. This strain was backcrossed 8 times to C57BL/6 by the donating laboratory. This is a low expressor line (404-4).

Health & husbandry
The genotypes of the animals provided may not reflect those discussed in the strain description or the mating scheme utilized by The Jackson Laboratory prior to cryopreservation. Please inquire for possible genotypes for this specific strain.
Health & Colony Maintenance Information
Animal Health Reports
Production of mice from cryopreserved embryos or sperm occurs in a maximum barrier room, G200.Colony Maintenance
Breeding & Husbandry When maintained as a live colony, hemizygotes may be bred. Integration of the transgene near the agouti allele (associated with the non-agouti gene a on mouse Chromosome 2) may have occurred because many of the transgenic animals are agouti in color despite many backcrosses to C57BL/6 (black).

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.Ordering Information
