Detailed Description

Homozygous null mice have an embryonic lethal phenotype, failing to develop past embryonic day 8.5. Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and are more active than wildtype littermates. A reduced level of protein gene product is detected by immunoprecipitation and Western blot analysis of brain, testes and kidney, but protein levels are not reduced in liver. Beta galactosidase activity in heterozygotes aged embryonic day 13.5 is found in the developing lens and spinal cord. In adult heterozygotes, beta galactosidase activity is detected throughout the brain, especially in the cerebellar Purkinje cells and hippocampus. Beta galactosidase activity patterns mimic the endogenous gene expression pattern. NTE activity in brain tissue is reduced by 40%. Heterozygotes are more sensitive to organophosphate toxicity with increased motor activity and mortality. This mutant mouse strain may be useful in studies of neuropathological hyperactivity, Gulf War Syndrome, and organophosphate-induced sub-acute neurotoxicity.

Development

A targeting vector containing lacZ, neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exons 4 to 10. The lacZ coding sequence was inserted into exon 4, and exons 5 to 10 were deleted. The construct was electroporated into 129S6/SvEvTac-derived TC1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts. The resulting chimeric animals from two independent ES cell clones were crossed. The offspring were mated to 129S1/SvImJ (STOCK#2448) mice.

Expression Data

Expressed Gene	lacZ, beta-galactosidase, E. coli
Site of Expression	lacZ expression in heterozygotes at embryonic day 13.5 is found in the developing lens and spinal chord. In adults, beta-galgalactosidase is detected throughout the brain, especially in the cerebellar Purkinje cells and the hippocampus.

Mammalian Phenotype Terms by Genotype

The following phenotype information is associated with a similar, but not exact match to this JAX^® Mice strain

Genotype: Pnpla6^tm1Blw/Pnpla6^tm1Blw
involves: 129S6/SvEvTac * C57BL/6J

embryo phenotype

decreased embryo size
- at E9, mutant embryos appear runted

embryonic growth retardation
- at E9, mutant embryos appear developmentally retarded relative to wild-type embryos

embryonic growth arrest
- mutant embryos are growth arrested at E10 and E11

abnormal neural tube closure
- mutant embryos display abnormal closing of the neural tube

growth/size/body region phenotype

decreased embryo size
- at E9, mutant embryos appear runted

embryonic growth retardation
- at E9, mutant embryos appear developmentally retarded relative to wild-type embryos

mortality/aging

embryonic lethality during organogenesis, complete penetrance
- no homozygotes are observed after E11
- homozygotes are observed at a reduced frequency after E8; first signs of resorption are evident at E9

nervous system phenotype

abnormal neural tube closure
- mutant embryos display abnormal closing of the neural tube

Genotype: Pnpla6^tm1Blw/Pnpla6⁺
involves: 129S6/SvEvTac * C57BL/6J

behavior/neurological phenotype

increased vertical activity
- after exposure to EOPF (1 mg per kg body weight), the number of vertical events is significantly higher in wild-type mice than in heterozygous mutant mice
- under baseline conditions, heterozygotes show a significantly higher number of vertical rearing events than wild-type mice over a 10-day test period in an open-field chamber

hyperactivity
- after exposure to EOPF (1 mg per kg body weight), motor activity is significantly higher in wild-type mice than in heterozygous mutant mice, indicating that even a minor chemical reduction of enzyme activity can lead to hyperactivity
- heterozygotes display higher baseline levels of motor activity than wild-type mice, as determined by total distance traveled and vertical rearing events in an open-field chamber over a 10-day test period

homeostasis/metabolism phenotype

increased sensitivity to xenobiotic induced morbidity/mortality
- heterozygotes exhibit significantly higher mortality rates than wild-type mice after i.p. injection of ethyl octylphosphonofluoridate (EOPF), an organophosphate compound that causes delayed neurotoxicity, at both 6 mg and 10 mg EOPF per kg body weight
- Normal - however, no mortality or neuropathological effects are noted in either wild-type or heterozygous mutant mice with 1 mg EOPF per kg body weight

mammalian phenotype

behavior/neurological phenotype
- Normal - under baseline conditions, heterozygotes display no gross defects in learning and memory or anxiety relative to wild-type mice

mortality/aging

increased sensitivity to xenobiotic induced morbidity/mortality
- heterozygotes exhibit significantly higher mortality rates than wild-type mice after i.p. injection of ethyl octylphosphonofluoridate (EOPF), an organophosphate compound that causes delayed neurotoxicity, at both 6 mg and 10 mg EOPF per kg body weight
- Normal - however, no mortality or neuropathological effects are noted in either wild-type or heterozygous mutant mice with 1 mg EOPF per kg body weight

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
