| 002052 | B6.129P2-Apoetm1Unc/J | Level 1 |
| Mice homozygous for the Apoetm1Unc mutation show a marked increase in total plasma cholesterol levels that are unaffected by age or sex. Fatty streaks in the proximal aorta are found at 3 months of age. The lesions increase with age and progress to lesions with less lipid but more elongated cells, typical of a more advanced stage of pre-atherosclerotic lesion. Moderately increased triglyceride levels have been reported in mice with this mutation on a mixed C57BL/6 x 129 genetic background. Aged APOE deficient mice (>17 months) have been shown to develop xanthomatous lesions in the brain consisting mostly of crystalline cholesterol clefts, lipid globules, and foam cells. Smaller xanthomas were seen in the choroid plexus and ventral fornix. Recent studies indicate that APOE deficient mice have altered responses to stress, impaired spatial learning and memory, altered long term potentiation, and synaptic damage. | ||
| 004633 | B6.Cg-Tg(GFAP-APOE*3)37Hol Apoetm1Unc/J | Repository- Live |
| These transgenic mice express the human apolipoprotein E3 isoform (APOE3) under the direction of the human glial fibrillary acidic protein (GFAP) promoter and do not express endogenous mouse apolipoprotein E (APOE). The transgenic isoform expression pattern follows the endogenous mouse APOE and GFAP expression patterns in the brain. Human APOE3 is immunodetectable in glia and neuropil in developing and adult mutant mice. Cultured astrocytes from transgenic mice secrete APOE3 in lipoproteins that are similar in size to high-density (HDL) plasma lipoproteins. Detergent-soluble APOE3 protein levels in hemizygous mice forebrain tissue and in adult human cortex tissue are similar. Mice that are hemizygous or homozygous for the transgenic insert and homozygous for the targeted allele are viable, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain represents a model that may be useful in studies examining the function of APOE3 in t

| 002246 | B6.129-Apoetm1Unc Ldlrtm1Her/J | Repository-Cryopreserved |
| Mice homozygous for the Apoetm1Unc and Ldlrtm1Hertargeted mutations on a normal chow diet show cholesterol levels corresponding to those seen in the Apoetm1Unc targeted mutant strain. The lipoprotein pattern in homozygous mice also resembles that seen in the Apoetm1Unc targeted mutant strain (VLDL & chylomicron remnants). The double targeted mice have a marked increase in both APOB48 and APOB100. In addition, APOAIV is increased. | ||

| 002878 | B6;129-Apobtm1Sgy Apoetm1Unc/J | Repository-Cryopreserved |
| Mice homozygous for the Apobtm1Sgy and Apoetm1Unc targeted mutations do not express the apolipoproteins B100 or E. They do retain the ability to express apolipoprotein B48. They have the highest total cholesterol (392 mg/dl vs 341 for Apobtm1Unc/Apoetm1Unc); highest LDL cholesterol (APOB48 is not a ligand for LDLR), and atherosclerotic lesions more extensive than Apoetm1Unc/Apoetm1Unc homozygotes. The extent of atherosclerosis correlated significantly with plasma cholesterol levels. | ||
| 002879 | B6;129-Apobtm2Sgy Apoetm1Unc/J | Repository-Cryopreserved |
| Mice homozygous for the Apobtm2Sgy and Apoetm1Unc targeted mutations do not express the apolipoproteins B48 or E, they do express APOB100. Homozygotes are viable and fertile with no overt abnormalities. Compared to the APOB48 APOE deficient mice and the APOE deficient mice, they have the lowest total cholesterol (247mg/dl), lowest LDL cholesterol, and the least extensive Atherosclerotic lesions. The extent of atherosclerosis correlated significantly with plasma cholesterol levels. | ||
| 002245 | B6;129-Apoetm1Unc Ldlrtm1Her/J | Repository-Cryopreserved |

The lipoprotein pattern in homozygous mice also resembles that seen in the Apoetm1Unc targeted mutant strain (VLDL & chylomicron remnants).

| 004362 | B6;129-Scarb1tm1Kri Apoetm1Unc/J | Repository-Cryopreserved |
| At birth, mice homozygous for both targeted alleles are viable, normal in size and do not display any gross physical or behavioral abnormalities. All double mutants die between 5 to 8 weeks following birth, exhibiting hypercholesterolemia and significantly lower body weights compared to control mice. Mice display an altered appearance several days before death, displaying ruffled fur, an abnormal gate and sometimes labored breathing. Hearts from double mutants are enlarged, exhibit evidence of myocardial infarction and are functionally impaired. Histological examination reveals extensive coronary artery disease characterized by atherosclerotic plaques with evidence of cholesterol clefts and fibrin deposition. As with other Scarb1 homozygous null mutants, females are infertile while the fertility of homozygous males remains intact. This double mutant mouse strain offers a model that may be a useful tool in studies related to coronary heart disease. | ||

New Strains Under DevelopmentThe Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.
- Receive periodic updates on the status of the colony UNDER DEVELOPMENT
- Obtain advance notification of strain availability and opportunity to order prior to the strain being published as available
- Provide input affecting speed and quantity of availability
It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
