Strain Description
Compared with their wildtype siblings, anx/anx homozygotes are characterized by a thinning in the neck and tail at 5 days of age, lower body weight detectable by 9 days of age, and death by 22 days of age on the B6C3H-a/a background. Outbreeding to CAST/Ei modifies the phenotype such that homozygotes live to approximately 5 weeks of age. Evaluation of stomach content shows that anx/anx mice ingest less than their siblings. They show headweaving, body tremors, uncoordinated gait, and hyperactivity along with diminished adipose tissue and reduced serum leptin levels. (Maltais et al., 1984; Johansen et al., 2000)

Intraperitoneal injection of 20 day old pups with 5,7-dihydroxytryptamine, a seratonin antagonist, reduces the severity of the neurological phenotypes. Homozygotes have extensive serotonergic hyperinnervation in normal target fields including the hippocampus, frontal cortex, olfactory bulb, and cerebellum, yet they have normal catecholaminergic innervation. This hyperinnervation is thought to reflect increased arborization of axonal fibers since there is no increase in serotonergic cell bodies. In the raphe nuiclues, there are decreased mRNA levels of serotonin transp orter (Slc6a4 previously Htt or 5-Htt) and tryptophan hydroxylase activity is diminished. Similar to food deprived wild type mice, anx/anx mice show decreased mRNA of monoamine oxidase A in the locus ceruleus but not the raphe nuclei. (Maltais et al., 1984; Son et al., 1994; Jahng et al., 1998, Brain Res; Jahng et al., 1998, Dev Brain Res.)

Despite their failure to eat adequately, homozygotes do not show elevated neuropeptide Y mRNA levels in the hypothalamic arcuate nucleus. However, immunohistochemistry revealed increased perikaryal neuropeptide Y staining in the arcuate nucleus and decreased density and neuropeptide Y staining of neuropeptide Y terminals in the paraventricular, arcuate, and other hypothalamic nuclei. Neuropeptide Y staining in the suprachiasmatic and thalamic paraventricular nuclei is normal. There is a similarly altered pattern of expression for agouti gene-related protein with immunoreacitvity increased in the cell body and decreased in the terminals in arcuate neurons despite apparently normal mRNA levels. (Broberger et al., 1997; Jahng et al., 1998, Brain Res; Broberger at el., 1998)

The arcuate nucleus also has a reduction in the number of pro-opiomelanocortin expressing neurons, a reduction in mRNA levels of pro-opiomelanocor tin and neuropeptide Y receptors Y1 and Y5, and a reduction in immunoreactivity of neuropeptide Y receptor Y2, adrenocorticotropic hormone, and alpha melanocyte stimulating hormone. Decreased staining of aspartate, acetylcholinesterase, and somatostatin was also seen in the arcuate nucleus. Decreased staining of cocaine and amphetamine regulated transcript in the arcuate nucleus and other regions of the hyopthalamus has also been reported. This pattern of decreased staining of pro-opiomelanocortin neurons may be due to degeneration of this cell population. No changes in brain cholecystokinin, galanin, or serotonin were detected by immunohistochemistry. (Broberger et al., 1997; Broberger et al., 1999; Johansen et al., 2000.)

The dentate gyrus of anx/anx mice is smaller than normal and has an increase in both the number of proliferating cells and cells undergoing apoptosis according to BrdU and TUNEL assessment. (Kim et al., 2001.)

Supply Details

Standard SupplyRepository-Cryopreserved. Must Be Recovered. Please refer to the Supply Notes for further information.
Supply Notes Cryorecovery of Strains Needing Progeny Testing.
The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two untested males and two untested females (two pairs) will be recovered, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the overall recovery time to approximately 25 weeks. However, all pups recovered will be sent.

Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available. This type of testing involves breeding the recovered animals and assessing the phenotype of the offspring in order to identify animals carrying the mutation of interest. We can perform the progeny testing for you as a service or we can ship all recovered animals (at least two untested pairs) to you for progeny testing at your facility. If you perform the progeny testing, there is NO guarantee that a carrier will be identified. If we perform progeny testing as a service, additional breeding time will be required. In this case, when a male and female (one pair) are identified that carry the mutation, they and their offspring will be shipped. Delivery time for strains requiring progeny testing often exceeds 25 weeks and may take 12 months or more due to the difficulties in breeding some strains. The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation. Please note that identified pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Please contact Customer Service for more information on the cost of progeny testing for a strain: Tel: 1-800-422-6423 or 1-207-288-5845.

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.
