Mating System +/+ sibling x Hemizygote (Female x Male) 03-SEP-08 Species laboratory mouse Generation N11p
Generation DefinitionsDonating Investigator Ted Abel, University of Pennsylvania Description
Mice hemizygous for the transgene are viable and fertile with no gross anatomical abnormalities or structural lesions within the hippocampus or other regions. Transgene expression is observed in hippocampus (CA1, CA3, and dentate gyrus), neocortex, olfactory bulb, striatum, and amygdala. Transgenic mice have a 50% reduction in basal cAMP-dependent protein kinase A (PKA or PRKACA) activity, defective protein synthesis-dependent late phase of long-term potentiation, and reduced place cell stability in hippocampus. Mice have defective long-term, but not short-term, memory in hippocampus-based spatial and non-spatial tasks. This parallels the phenotype observed in mice treated with inhibitors of PKA or inhibitors of protein synthesis. Functional magnetic resonance imaging reveals reduced CA1 hippocampal signal. Transgenic mice are more sensitive to ethanol-induced sedation. Mice expressing this transgene may be useful in a wide variety of memory studies, including Alzheimer's disease, hippocampus-dependent long term memory, protein synthesis-dependent memory, amnesia, or age-related memory decline.Development
The cAMP-dependent protein kinase A (PKA or PRKACA) RIalpha regulatory subunit, R(AB), was mutated at both cAMP binding sites and placed under control of the mouse Camk2a promoter. The resulting construct was injected into the pronuclei of (B6CBAF1/J x B6CBAF1/J) zygotes. Chimeric males (founder line 426, R(AB)-2) were bred to C57BL/6J females. At some point, hemizygotes were bred to B6CBAF1/J to rescue the line. After the rescue, hemizygotes were bred to C57BL/6J for more than 10 generations before arrival at The Jackson Laboratory.

Phenotype
Phenotype Information
assigned by genotype
The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.
Tg(Camk2a-Prkaca)426Tabe/0
involves: C57BL/6J * CBA/J
- homeostasis/metabolism phenotype
- abnormal enzyme/coenzyme activity
- in transgenics, basal PKA activity in hippocampal extracts (239 pmol/min/mg) is 50% of wild-type (499 pmol/min/mg); when kinase is activated with 5 um cAMP, activity is attenuated by 25% with respect to wild-type mice. (MGI Ref ID J:38837)
- behavior/neurological phenotype
- abnormal contextual conditioning behavior
- mutants have normal short term memory in tests but long term memory is severely defective compared to wild-type (MGI Ref ID J:38837)
- training mice with a single conditioned stimulus (CS)/ unconditioned stimulus (US) pairing and testing mice 1, 3, 6, and 24 hours after training shows similar responses in transgenic and control mice at 1 hour, but dramatic reduction in contextual fear responses relative to wild-type at 3, 6, and 24 hours post-training; this indicates short term memory is normal in mutants, but long term memory is impaired (MGI Ref ID J:110284)
- similar results are obtained when control mice are treated with the PKA inhibitor Rp-cAMPs prior to training (MGI Ref ID J:110284)
- abnormal spatial learning
- in a probe trial of the Morris water maze test, mutants search less selectively and spend less time in the target quadrant than control mice, but mutants do not have reduced visual acuity or motor coordination (MGI Ref ID J:38837)
- decreased alcohol consumption
- transgenic mice show decreased ethanol preference and consumption compared to wild-type (MGI Ref ID J:70175)
- impaired righting response
- mice are more sensitive to ethanol-induced sedation than wild-type (MGI Ref ID J:70175)
- nervous system phenotype
- reduced long term potentiation
- when four 100 Hz trains are applied to hippocampal slices from mutant mice, it elicits a continually decaying potentiation (fEPSP slopes - 202%, 144% and 107% at 20, 60 and 180 minutes); in wild-type this stimulation induces robust, long-lasting L-LTP (fEPSP slopes - 123%, 199% and 176% at 20, 60 and 180 minutes); early-LTP induced by one or two stimuli is unchanged in mutants (MGI Ref ID J:38837)
- there is a defect in Schaffer collateral L-LTP (MGI Ref ID J:38837)

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
