| 006503 | B6.129S4-Lpltm1Ijg/J | Repository- Live |
| These mice possess loxP sites on either side of exon 1 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When used in conjunction with a Cre recombinase-expressing strain, this strain is useful in generating tissue-specific mutants of the floxed allele. These mice may be useful for cardiovascular studies (such as lipid metabolism and fat storage) and obesity research. | ||
| 007682 | B6.129X1-Apobtm1.1Zc/J | Repository- Live |
| Mice homozygous for this apoB38.9 allele (apoB38.9/38.9) are viable with impaired fertility, bearing a premature stop codon at residue 1767 of the targeted gene. As a result, homozygous plasma shows a truncated apoB38.9 as the sole apoB protein. Plasma from heterozygous (apoB+/38.9) mice have reduced apoB100 and apoB48 compared to wildtype, with apoB38.9 representing 20% of total circulating apoB. This apoB38.9 truncation affects both apoB100 and apoB48 metabolism in mice, and mimics human Familial Hypobetalipoproteinemia (FHBL). Homozygous and, to a lesser extent, heterozygous mice exhibit symptoms of FHBL due to impaired lipoprotein export system/VLDL secretion, including elevated hepatic triglyceride (TG), cholesterol and free fatty acids (FFA), with decreased plasma TG and cholesterol. Because plasma and liver lipid profiles range from mild to severe in populations of heterozygous apoB38.9 mice on a mixed (C57BL/6J;129X1/SvJ) genetic background, apoB+/38

| Mice that are homozygous for the targeted mutation are viable, fertile and do not display any gross physical abnormalities. Mutant mice exhibit exercise intolerance when challenged and are slightly hyperphagic. No gene product (protein) is detected by Western blot analysis in adipose, lung and heart tissues or in cultured mouse embryonic fibroblasts (MEFs). A decrease in the level of co-expressed caveolin-2 protein is immunodetected. At age 4-5 months, mutant mice are often smaller than their wildtype littermates. By one year of age, mutant mice weigh 5 to 7 grams less than wildtype, and are resistant to diet-induced obesity. Progressive adipose pathology results in reduced white adipose tissue with abnormally small adipocytes and enlarged, hyperplastic brown adipose tissue. Homozygotes display lipid metabolism and uptake disruption with elevated serum triglycerides and free fatty acid levels, and reduced leptin levels. Isolated aortic tissue segments have a diminished vasoconstriction

| 006907 | B6;CBA-Tg(APOC3)3707Bres/J | Repository- Live |
| Mice hemizygous for this "human apo CIII" transgene are viable and fertile. This high expressor founder line (3703) exhibits transgene expression primarily in the liver with some intestinal expression as well. Hemizygous mice have severe plasma hypertriglyceridemia and significantly increased plasma cholesterol. However, resistance to insulin-mediated glucose uptake or hyperinsulinemia are not observed. This high expressor human apo CIII transgenic strain may be useful in studying lipid metabolism, very low density lipoproteins (VLDL), hypertriglyceridemia, coronary heart disease, and/or atherosclerosis. | ||
| 004824 | BTBR.V(B6)-Lepob/WiscJ | Repository- Live |
| Mice homozygous for the obese spontaneous mutation, (Lepob commonly referred to as ob or ob/ob) exhibit obesity hyperphagia, a diabetes-like syndrome of hyperglycemia, glucose intolerance, elevated plasma insulin, subfertility, impaired wound healing, and an increase in hormone production from both pituitary and adrenal glands. They are also hypometabolic and hypothermic. The obesity is characterized by an increase in both number and size of adipocytes. Although hyperphagia contributes to the obesity, homozygotes gain excess weight and deposit excess fat even when restricted to a diet sufficient for normal weight maintenance in lean mice. Hyperinsulinemia does not develop until after the increase body weight and is probably the result of it. Homozygotes do have an abnormally low threshold for stimulation of pancreatic islet insulin secretion even in very young preobese animals. As is the case with mice carrying the diabetes mutation (Leprdb

| 007744 | C57BL/6-Tg(APOE-DGAT2)24Far/J | Repository- Live |
| Mice hemizygous for this LivLE6-DGAT2 transgene are viable and fertile, with human DGAT2 expression directed to the liver by the hepatic promoter/enhancer sequences from the human apolipoprotein E gene. Mice from founder line 24 (referred to as Liv-DGAT2-low) have an approximately 2-fold increase in total hepatic DGAT2 mRNA/protein expression, with no reported overexpression in kidney, brain, or skeletal muscle. As DGAT2 is one of two enzymes that catalyze the final step of triacylglycerol (TG) biosynthesis, transgenic mice develop hepatic steatosis with increased hepatic TG and insulin signaling lipid (diacylglycerol, ceramide and unsaturated Fatty AcylCoA) content. Liv-DGAT2-low mice also exhibit increased transcription of fatty acid synthesis genes (SREBP-1c, fatty acid synthase, and stearoyl CoA desaturase 1). Fasted mice show a 65% decrease in plasma TG, but are not insulin resistant (blood glucose and insulin are similar to wildtype). Liv-DGAT2-low mice challenged with a high-fat

| 006781 | C57BL/6-Tg(Ckm-DGAT2)10Far/J | Repository- Live |
| Mice hemizygous for this MCK-DGAT2 transgene are viable and fertile. Under direction of the mouse muscle creatine kinase (MCK) promoter, these mice overexpress human acyl CoA:diacylglycerol acyltransferase 2 (DGAT2) in striated skeletal muscles, specifically glycolytic (rather than oxidative) muscle. DGAT2 overexpression leads to increased lipid deposition (triacylglycerol, ceramide, and fatty acyl CoA) in glycolytic muscle. This lipid accumulation leads to impaired insulin signaling (insulin resistance), glucose uptake, and glucose tolerance in this tissue, as well as whole-body glucose intolerance. These MCK-DGAT2 transgenic mice may be useful in studying lipid accumulation in skeletal muscle, insulin and glucose metabolism, obesity, and type 2 diabetes. Of note, these mice may also be useful in conjunction with Liv-DGAT2-low transgenic mice (Stock No. 007744) which exhibit DGAT2 overexpression directed to hepatic tissue. | ||

| 003538 | B6.Cg-Tg(APOC2)2Bres/J | Repository-Cryopreserved |
| Mice carrying the human apolipoprotein CII transgene are viable and fertile. Transgenic mice show hypertriglyceridemia and have delayed clearance of VLDL-triglyceride. This strain is a model for hyper-triglyceridemia due to decreased lipolysis. In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available. | ||
| 002924 | B6;CBA-Tg(APOC1)1Bres/J | Repository-Cryopreserved |
| Mice carrying the human apolipoprotein CI transgene are viable and fertile. They show elevated plasma triglycerides in both fasted and fed states. They also have elevated plasma cholesterol, increased VLDL, increased LDL, increased plasma APOB, and slowed clearance of both VLDL triglycerides and postlipolysis lipoprotein remnants. This strain serves as a model of decreased clearance of postprandial triglycerides and lipoprotein remnants. | ||

| Transgenic mice overexpress a dominant-positive truncated form of human sterol regulatory element-binding protein-2 (SREBF2) in liver and adipose tissue. Livers from transgenic mice have increased mRNA levels for genes encoding multiple enzymes of cholesterol and fatty acid biosynthesis as well as the LDL receptor. In vivo cholesterol and fatty acid synthetic rates in livers from transgenic mice are increased 28- and 4-fold, respectively. | ||

| Homozygous fatty liver dystrophy (fld) mice have an enlarged, fatty liver and hypertriglyceridemia which resolve to normal during the weaning transition. However, decreased overall size, decreased lipid in the fat pads, and a peripheral neuropathy persist throughout the lifespan. This peripheral neuropathy manifests as a tremor and an unsteady gait shortly after 10 days of age and worsens with age. The fld neuropathy is specific to the peripheral nervous system. Electron microscopy of sciatic nerves revealed thin, poorly compacted myelin sheaths, hypertrophic Schwann cells, myelin debris, degenerating axons, bands of Bugner, and regenerative clusters, but no evidence of inflammation (Langner et al, 1991). Western blot analysis of sciatic nerve from two-to-three month old fld/fld mice showed a 7-13-fold reduction in myelin P0, a vast increase in apoE, an increase in GAP-43, and no detectable myelin P2. It was also noted that a
