Targeted Mutation

Cryo Recovery

Overview

These Dld (dihydrolipoamide dehydrogenase or E3 component) mutant mice may be useful to study early murine embryonic metabolism, including glucose and mitochondrial metabolism during the early postimplantation period. As altered energy metabolism and reductions in alpha-ketoacid dehydrogenase complexes have also been associated with many neurodegenerative disorders, these mice may also be useful in studies related to Parkinson's disease, Huntington's disease, and/or Alzheimer's disease. Because the metabolic disturbances associated with E3 deficiency (Dld deficiency) cause a variant of Maple Syrup Urine Disease (MSUD) in which there is an accompanying lactic acidosis due to concomitant deficiency of pyruvate dehydrogenase complex, these mice may be useful in such studies or in conjunction with iMSUD mice (Stock No. 006999).

Detailed Description

Mice heterozygous for the Dld (dihydrolipoamide dehydrogenase or E3 component) targeted mutation are viable and fertile. Heterozygous mice exhibit approximately half of wild-type enzymatic activity levels for E3 and all affected mitochondrial multienzyme complexes. Heterozygotes (on a C57BL/6;129P2 genetic background) exhibit increased vulnerability to treatments with MPTP (dopaminergic neurotoxin used to induce Parkinson's disease-like lesions), malonate (inhibitor of cellular respiration used to mimic Huntington's disease features), and 3-NP (mitochondrial toxin used to mimic Huntington's disease features). Homozygous mice exhibit normal development and metabolism during the preimplantation period, explained by the persistence of E3 enzyme from the oocyte. Homozygotes exhibit developmental delays shortly after implantation (7.5 to 8.5 days postcoitum (dpc)) and cease development within the subsequent two days. These Dld mutant mice may be useful to study early murine embryonic metabolism, including glucose and mitochondrial metabolism during the early postimplantation period. As altered energy metabolism and reductions in alpha-ketoacid dehydrogenase complexes have also been associated with many neurodegenerative disorders, these mice may also be useful for studying Parkinson's disease, Huntington's disease, and/or Alzheimer's disease. Because the metabolic disturbances associated with E3 deficiency (Dld deficiency) cause a variant of Maple Syrup Urine Disease (MSUD) in which there is an accompanying lactic acidosis due to concomitant deficiency of pyruvate dehydrogenase complex, these mice may be useful in such studies or in conjunction with iMSUD mice (Stock No. 006999).

Development

A targeting vector was designed to insert a beta actin promoter-driven neomycinphosphotransferase gene (lacking a polyA signal) into exon 10 of the targeted gene. The construct was electroporated into 129P2/OlaHsd-derived E14.1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and chimeric males were bred with C57BL/6 females to produce heterozygous mutant mice. These heterozygotes were subjected to an additional round of breeding with C57BL/6J inbred mice, and then maintained by interbreeding of heterozygous animals for many generations prior to arrival at The Jackson Laboratory. Upon arrival, mutant mice were bred to C57BL/6J for at least one generation to establish the colony.

Allele Symbol: Dld^tm1Ptl

Allele Name	targeted mutation 1, Mulchand S Patel
Allele Type	Targeted (Null/Knockout)
Allele Synonym(s)	Dld^-; Dld^tm1mjp
Gene Symbol and Name	Dld, dihydrolipoamide dehydrogenase
Gene Synonym(s)	AI315664; AI746344; DLDD; DLDH; E3; GCSL; LAD; PHE3; branched chain alpha-keto acid dehydrogenase complex subunit E3; dihydrolipoyl dehydrogenase; expressed sequence AI315664; expressed sequence AI746344
Strain of Origin	129P2/OlaHsd
Chromosome	12
Molecular Note	Exon 10 was disrupted by the insertion of a neomycin selection cassette. Northern blot analysis of total hepatic and renal RNA showed that transcript levels are reduced by approximately 50% in heterozygous mice. RT-PCR analysis confirmed that the neo transgene was not excised via an altered splicing pattern.

mortality/aging

embryonic lethality between implantation and somite formation, complete penetrance
- homozygous null embryos exhibit peri-gastrulation lethality and are resorbed by 9.5 dpc

embryo phenotype

abnormal visceral endoderm morphology
- at 7.5 dpc, the mutant visceral endoderm appears to proliferate relatively longer and forms a thickened columnar layer instead of the unicellular flat squamous layer found in wild-type

decreased embryo size
- at 7.5 dpc, mutant embryos are noticeably smaller than wild-type embryos

embryonic growth arrest
- homozygous null embryos display a developmental cessation at the onset of gastrulation
- no mutant embryos develop normally to 8.5 dpc

embryonic growth retardation
- at 7.5 dpc, mutant embryos resemble 6.5-dpc wild-type egg cylinders in size and proportion
- homozygous null embryos display a developmental delay at 7.5 dpc

growth/size/body region phenotype

decreased embryo size
- at 7.5 dpc, mutant embryos are noticeably smaller than wild-type embryos

embryonic growth retardation

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

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.
