| 000664 | C57BL/6J | Level 1 |
| C57BL/6 is the most widely used inbred strain. It is commonly used as a general purpose strain and background strain for the generation of congenics carrying both spontaneous and induced mutations. Although this strain is refractory to many tumors, it is a permissive background for maximal expression of most mutations. C57BL/6J mice are used in a wide variety of research areas including cardiovascular biology, developmental biology, diabetes and obesity, genetics, immunology, neurobiology, and sensorineural research. C57BL/6J mice are also commonly used in the production of transgenic mice. Overall, C57BL/6 mice breed well, are long-lived, and have a low susceptibility to tumors. Primitive hematopoietic stem cells from C57BL/6J mice show greatly delayed senescence relative to BALB/c and DBA/2J. This is a dominant trait. Other characteristics include: 1) a high susceptibility to diet-induced obesity, type 2 diabetes, and atherosclerosis; 2) a high incidence of microphthalmia and other a

| 000648 | AKR/J | Level 2 |
| Originally inbred at the Rockefeller Institute, AKR mice are widely used in cancer research for their high leukemia incidence (60-90%) and in immunology as a source of the Thy1.1 (theta AKR) antigen. AKR/J mice are viremic from birth, and express the ecotropic retrovirus AKV in all tissues. The hair interior defect (hid) mutation, a strain characteristic of AKR mice, causes alterations in hair development that is only evident microscopically. Adrenocortical lipid depletion (ald) in AKR mice is caused by a mutation in sterol O-acyltransferase 1 (Soat1), and leads to a truncated SOAT1 protein. AKR/J mice are relatively resistant to aortic lesion formation on a semi-synthetic high fat diet and are hyporesponsive to diets containing high levels of fat and cholesterol. | ||
| 000632 | B6.V-Lepob/J | Level 2 |
| Mice homozygous for the obese spontaneous mutation, (Lepob; commonly referred to as ob or ob/ob), are first recognizable at about 4 weeks of age. Homozygous mutant mice gain weight rapidly and may reach three times the normal weight of wildtype controls. In addition to obesity, mutant mice exhibit 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 adipocyte number and size. 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 in body weight, and probably results from it. Homozygotes have an abnorm

| 000642 | BKS.Cg-m +/+ Leprdb/J | Level 2 |
| Mice homozygous for the diabetes spontaneous mutation (Leprdb) become identifiably obese around 3 to 4 weeks of age. Elevations of plasma insulin begin at 10 to 14 days of age and of blood sugar at 4 to 8 weeks. Homozygous mutant mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. A number of features are observed on the C57BLKS background, including an uncontrolled rise in blood sugar, severe depletion of the insulin-producing beta-cells of the pancreatic islets, and death by 10 months of age. Exogenous insulin fails to control blood glucose levels and gluconeogenic enzyme activity increases. Peripheral neuropathy and myocardial disease are seen in C57BLKS-Leprdb homozygotes. Wound healing is delayed, and metabolic efficiency is increased. Female homozygotes exhibit decreased uterine and ovarian weights, decreased ovarian hormone production and hypercytolipidemia in follicular granul

| 000654 | CBA/CaJ | Level 2 |
| The CBA inbred strain was initially bred for longevity and a low incidence of spontaneous mammary tumors (compared with C3H). Burdette and Strong reported that CBA mice were comparatively susceptible to tumor induction after a single subcutaneous injection of methylcholanthrene. The tumor types identified in this early work in CBA mice included spindle cell sarcoma, rhabdomyosarcoma, and epidermoid carcinoma. Strong and Smith reported finding benign hepatomas in aging CBA mice. Several groups confirmed this finding, and the majority of studies found a higher frequency of spontaneous hepatomas in males than in females.
CBA/Ca mice are commonly used for leukemogenesis research because this strain has a low spontaneous incidence of leukemia but has a relatively high inducibility of myeloid leukemia in response to benzene and radiation exposure. Multiple reports using CBA, its F1 hybrids, and other strains, have indicated that deletions in a specific segment of chromosome 2 are linked

| 002468 | KK.Cg-Ay/J | Level 2 |
| Ay and other mutations at the a locus conferring a completely yellow coat color are dominant to all a alleles that produce a darker coat. Hair pigment of Ay heterozygotes is yellow, but eyes are black. Heterozygotes usually become obese and infertile within a few months after birth. Increased adipose tissue mass is due to fat cell hypertrophy, and it has been hypothesized that the obesity results from the observed reduction in hypothalamic norepinephrine and dopamine. Heterozygotes are more susceptible to several kinds of tumors than are normal mice, possibly due, at least in part, to a general increase in cell proliferation that also manifests as a slight increase in lean body mass and skeletal length. Further spleen cells from heterozygotes cause a significantly lower graft vs. host reaction. Mice homozygous for the yellow spontaneous mutation (Ay) die before implantation, or shortly thereafter. The time of de

| 004456 | NONcNZO10/LtJ | Level 2 |
| Onset of hyperglycemia occurs between 10-12 on a 10-11% fat (wt/wt) chow diet with greater than 85% diabetic by 18 weeks. Males exhibit increased serum triglycerides, moderate to severe liver steatosis and pancreatic islet atrophy similar to NZO/HlLt males. Serum insulin and leptin values are significantly lower than in NZO/HlLt, and are only moderately elevated above those recorded in NON/ShiLtJ males. Unlike the very obese NZO/HlLt mice, NONcNZO10/LtJ mice do not exhibit hyperphagia or hypercorticism and are much easier to breed. Although NONcNZO10/LtJ males develop only a moderate level of obesity compared to NZO/HlLt males, the interaction with known diabetogenic QTL from the NON/ShiLtJ strain produce an earlier onset and higher prevalence of chronic hyperglycemia than observed in NZO/HlLt males.
NONcNZO10/LtJ is differentially sensitive to adverse hepatic side effects of thiazolidinediones and may be useful for pharmac ogenetic analysis. This strain represents a model of polyg

| 000697 | B6.Cg-m +/+ Leprdb/J | Level 3 |
| Mice homozygous for the diabetes spontaneous mutation (Leprdb) become identifiably obese around 3 to 4 weeks of age. Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at 4 to 8 weeks. Affected mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. On the C57BL/6 background there is compensatory hyperplasia of the islet B-cells, and continued hyperinsulinemia throughout an 18- to 20-month life span. Wound healing is delayed and metabolic efficiency is increased. Although normal in body weight, blood glucose, and plasma insulin, heterozygotes (Leprdb/+) also have increased metabolic efficiency and can survive a prolonged fast longer than controls. Experiments involving destruction of the ventromedial nucleus of the hypothalamus suggest that Leprdb may cause a defect in the hypothalamus.

| 002810 | B6CBA-Tg(HDexon1)62Gpb/1J | Level 3 |
| This line is transgenic for the 5' end of the human HD gene carrying (CAG)115-(CAG)150 repeat expansions. The transgene is ubiquitously expressed. Transgenic mice exhibit a progressive neurological phenotype that mimics many of the features of HD, including choreiform-like movements, involuntary stereotypic movements, tremor, and epileptic seizures, as well as nonmovement disorder components, including unusual vocalization. They urinate frequently and exhibit loss of body weight and muscle bulk through the course of the disease. Neurologically they develop Neuronal Intranuclear Inclusions (NII) which contain both the huntingtin and ubiquitin proteins. Previously unknown, these NII have subsequently been identified in human HD patients. The age of onset of HD symptoms is reported to occur between 9 and 11 weeks. Commonly known as the "R6/2" strain. Transgenic mice develop hyperglycemia by 12 weeks of age with a corresponding decrease in insulin levels. Pancreatic beta cells develop

| 000662 | C57BLKS/J | Level 3 |
| Although C57BLKS/J is estimated to have more than 70% of its genome derived from C57BL/6J, these strains are phenotypically distinct. Diet-induced atherosclerotic lesions are much more severe in C57BLKS/J than in C57BL/6J or many other inbred strains. Compared with a panel of inbred strains, C57BLKS/J was found to have low total cholesterol and low HDL cholesterol when fed a normal diet and high total cholesterol and HDL cholesterol in an atherogenic diet. Paigen et al. found high levels of plasma bile salts in C57BLKS/J females after 8 weeks on an atherogenic diet. The mutations diabetes (Leprdb) and obese (Lepob) each express a much more severe phenotype on the C57BLKS/J background than on the C57BL/6J background. The Cpefat mutation causes severe obesity, hyperinsulinemia, and hyperglycemia on the C57BLKS/J background rather than the hyperinsulinemia, and mild obesity without hyperglycemia found on the HRS/J background.

| 003070 | ALR/LtJ | Repository- Live |
| ALS/LtJ (Stock No. 003072) and ALR/LtJ inbred strains are of interest to investigators across a wide range of scientific disciplines including type 1 and type 2 diabetes, obesity, metabolism and toxicology research. Treatment of alloxan or streptozotocin causing pancreatic beta cell destruction, leads to severe hyperglycemia and hypoinsulinemia in ALS/LtJ mice. ALR/LtJ mice are resistant to these toxins. ALR/LtJ mice are of particular interest to investigators studying the immunogenetics of NOD/LtJ mice in that the ALR/LtJ MHC haplotype (H2gx) is a variant of the diabetogenic NOD H2g7 haplotype. The (H2gx) haplotype is identical to the H2g7 haplotype from the H2-K end of the complex through the class II and class III region distal to Hsp70. However, at the distal H2-D end of the complex, ALR/LtJ mice have a rare H2-Dgx allele. Despite the similarities to the NOD/ShiLtJ mice, ALR/LtJ mice do not develop

| 003072 | ALS/LtJ | Repository- Live |
| ALS/LtJ and ALR/LtJ (Stock No. 003070) inbred strains are of interest to investigators across a wide range of scientific disciplines including type 1 and type 2 diabetes, obesity, metabolism and toxicology research. Treatment of alloxan or streptozotocin causing pancreatic beta cell destruction, leads to severe hyperglycemia and hypoinsulinemia in ALS/LtJ mice. ALR/LtJ mice are resistant to these toxins. By 34 wk of age, both untreated ALS/Lt and ALR/Lt males fed a 6% fat-containing chow diet attain a mean body weight of around 50 grams. Genome wide scan comparison shows that ALS/LtJ mice are more closely related to NON/ShiLtJ mice (they share the H2nb1 haplotype) than to NOD/ShiLtJ. Like two other ICR-derived inbred strains selected in Japan (NON and NSY), alloxan-untreated ALS/Lt males exhibit impaired glucose tolerance when tested by intraperitoneal administration of glucose. However, unlike NON/ShiLt males, which exhibit impaired glucose tolerance in the presence

| 000021 | B6.Cg-Ay/J | Repository- Live |
| Mice homozygous for the yellow spontaneous mutation (Ay) die before implantation or shortly thereafter. The time of death and type of abnormality is, in part, determined by the genetic background on which the mutation is placed. Hair pigment in heterozygous mice is yellow, but eyes are black. Heterozygotes usually become obese and infertile after the first few months. Increased adipose tissue mass is due to fat-cell hypertrophy. It has been hypothesized that the obesity results from the observed reduction in hypothalamic norepinephrine and dopamine levels. Insulin resistance and hyperglycemia follow development of hyperinsulinemia in early adulthood, although the degree is less severe than on the KK/UpJ genetic background (Stock No. 002468). Heterozygotes are also more susceptible to several kinds of tumors than normal mice, and their spleen cells cause a significantly lower graft vs. host reaction. The level of

| 006952 | B6.Cg-Akt2tm1.1Mbb Ldlrtm1Her/J | Repository- Live |
| Independently, homozygous Akt2 mutant mice develop insulin resistance and diabetes, while LDLR homozygotes are predisposed to atherosclerosis. Double mutant mice that are heterozygous for the Akt2 allele and homozygous for the LDLR mutation are viable and fertile. These double mutant mice may be useful in studies of diabetes, metabolism, hyperglycemia, and atherosclerosis. | ||
| 006966 | B6.Cg-Akt2tm1.1Mbb/J | Repository- Live |
| Mice homozygous for this Akt2 (thymoma viral proto-oncogene 2) mutant allele are viable and fertile. Homozygotes develop insulin resistance, hyperglycemia, impaired glucose tolerance, abnormal glucose uptake in muscle tissue, increased pancreatic beta-cell mass, and diabetes. 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. 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. | ||
| 003923 | B6.HRS(BKS)-Cpefat/J | Repository- Live |
| Mice homozygous for the fat spontaneous mutation (Cpefat) on a C57BL/6J genetic background (N10) become noticeably obese by 14-15 weeks of age. There is also some sexual dimorphism; female homozygous mutant mice develop obesity at a later age than males. Cpefat mice actually weigh less than wildtype controls prior to weaning age. Homozygous mutant mice develop a diabetic phenotype characterized by hyperglycemia and insulin resistance. Cpefat mice appear healthier on the C57BL/6J genetic background, avoiding the hereditary hydronephrosis present in C57BLKS/J and a lower incidence of malocclusion. | ||
| 006894 | B6;129-Mgat4atm1Jxm/J | Repository- Live |

| 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. | ||
| 006654 | FVB.BKS(D)-Leprdb/ChuaJ | Repository- Live |
| The phenotype of this congenic "FVB-db" strain varies from that previously published on other genetic backgrounds. Specifically, obese FVB-db mice show long-term hyperglycemia that is primarily due to severe insulin resistance. The hyperglycemia in the fed state persists despite escalating insulin secretion and a massive increase in pancreatic beta-cell mass. Obese FVB-db mice show evidence of mesangial matrix expansion, a hallmark of diabetic nephropathy. Whereas the original C57BLKS/J-db mice are hyperglycemic due to the development of hypoinsulinemia and loss of beta-cell mass, the hyperglycemia of FVB-db appears to be due to severe insulin resistance with continual increases in insulin secretory capacity from beta-cell mass expansion. As the phenotype varies by genetic background, these mutant mice, along with db mutants on other genetic backgrounds (see Stock No. 000642, For more information please see the full phenotype on the strain data sheet | ||

| 002423 | NON/ShiLtJ | Repository- Live |
| Although closely related to NOD mice, NON mice contain a diabetes resistant MHC haplotype (H2nb1 = Kb, Anb1, Ek, Db). The name was derived from "Non-Obese Non-diabetic"; however, NON/ShiLtJ mice should not be considered "normal." They carry the retinal degeneration (Pde6b) mutation and exhibit certain tendencies toward autoimmune disease. This strain maintains a low plasma insulin level, which may account in part why certain loci from NON/ShiLt can enhance development of autoimmune type 1 diabetes in segregating hybrid mice following outcross to NOD/ShiLtJ. The NON strain-characteristic immunologic abnormalities include perivascular/periductular leukocyte infiltration into the pancreas and submandibular salivary glands, and T lymphocytopenia evident by 20 weeks of age in spleen. NON/ShiLt mice clearly harbor genes predisposing to type 2 diabetes, as evidenced by early impaired glucose tolerance in males and females, d

| 005067 | NZL/LtJ | Repository- Live |
| Male NZL/LtJ mice develop juvenile-onset obesity and maturity-onset hyperglycemia (McInerney MF, et al., 2004). Over 90% of males exhibit hyperglycemia of >250 mg/dl by 20 weeks of age. Body weight in males increases to 55 gm by 16 weeks of age. The diabetic phenotype is very similar to that of NZO/HlLt J (Stock No. 002105) mice. An advantage of NZL/LtJ over NZO/HlLtJ as a diabetes model, in addition to the higher disease incidence, is that mice of this strain breed well, whereas NZO/HlLt mice breed very poorly. This strain carries the wildtype Igh-6 allele from the NZO/HlLtJ strain. | ||
| 005314 | TALLYHO/JngJ | Repository- Live |
| TALLYHO mimics many characteristics of human non-insulin-dependent type 2 diabetes mellitus (NIDDM). Male TallyHo mice develop hyperglycemia, hyperinsulinemia, hyperlipidemia, moderate obesity, and enlargement of the islets of Langerhans. Onset of hyperglycemia is delayed compared to ob/ob (B6.V-Lepob) and db/db (BKS.Cg- m +/+ Leprdb) mice beginning between 10 and 14 weeks of age. Female mice display moderate hyperinsulinemia, hyperlipidemia, and obesity but do not manifest overt diabetes (i.e. hyperglycemia). Chromosomal mapping identified a major diabetes susceptibility locus on Chr 19, designated Tanidd1 for TH-associated NIDDM. Breeding and mapping data suggest Tanidd1 is a single recessively inherited gene primarily responsible for the hyperglycemia phenotype in TALLYHO mice. Tanidd1 interacts with other loci including Tanidd2 on Chr 13, Tanidd3 on Chr 15, Tabw (TallyHo-associa

Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at 4 to 8 weeks. Homozygous mutant mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. Homozygous mutant mice on the 129P3/J background exhibit severe obesity but the diabetes phenotype is much reduced. | ||
| 000562 | B6(Cg)-Tubtub/J | Repository-Cryopreserved |
| Mice homozygous for the tubby spontaneous mutation experience maturity-onset obesity. Homozygous mutant mice are recognizable by increased body weight at 3 to 4 months in males and at 4 to 6 months in females. Both sexes are fertile. The increased weight is composed of excess adipose tissue. Blood glucose is normal, but plasma insulin is increased prior to obvious signs of obesity and may rise to 20 times normal by 6 months. Despite elevated plasma total cholesterol, triglycerides, and high-density lipoprotein cholesterol, homozygous mutant mice do not exhibit atherosclerotic fatty streak blood vessel lesions. Tubby mutant mice also exhibit retinal degeneration, initially believed due to the presence of another mutation which was called rd5, but since demonstrated to be a pleiotropic effect of the Tubtub mutation (Ohlemiller et al., 1997); the retinal phenotype is moderated by a QTL on Chromosome 11 (Ikeda et al., 2002).

| Glucokinase catalyzes a rate-limiting step in glucose metabolism in hepatocytes and pancreatic beta cells and is considered the "glucose sensor" for regulation of insulin secretion. Patients with maturity-onset diabetes of the young (MODY) have heterozygous point mutations in the glucokinase gene that result in reduced enzymatic activity and decreased insulin secretion. Disruption of the glucokinase gene results in a phenotype similar to MODY in heterozygous mice. These mice manifest a decreased insulin secretory response to glucose. | ||

| Homozygous mice are viable and fertile and do not express full length mRNA in heart, kidney, spleen, white adipose tissue, and pancreatic islets. In splenic mitochondria, endogenous protein was undetectable. When grown under high glucose conditions, cultured pancreatic islet cells from homozygous mice have increased insulin secretion and ATP levels compared to wildtype. Homozygous mice have 18% lower blood glucose levels. Whether fasting or fed, homozygotes have approximately 3-fold greater serum insulin due to increased insulin secretion. Similarly, glucose-stimulated insulin secretion is significantly increased. High fat diet-fed mice or palmitate-treated islets maintain pancreatic glucose responsiveness in vivo and in vitro compared to wildtype.

| Mice homozygous for the diabetes spontaneous mutation (Leprdb) become identifiably obese around 3 to 4 weeks of age. Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at 4 to 8 weeks. Affected mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. On the C57BL/6 background there is compensatory hyperplasia of the islet B-cells, and continued hyperinsulinemia throughout an 18- to 20-month life span. Wound healing is delayed, and metabolic efficiency is increased. Although normal in body weight, blood glucose, and plasma insulin, heterozygotes (Leprdb/+) also have increased metabolic efficiency, and can survive a prolonged fast longer than controls. Experiments involving destruction of the ventromedial nucleus of the hypothalamus suggest that Leprdb may cause a defect in the hypothalamus.

| Mice homozygous for the targeted allele are viable yet sterile and exhibit a progressive development of a type 2 diabetic phenotype. At birth, mice are slightly (10%) smaller than wildtype littermates. This weight difference is maintained from birth through adulthood. Elevated blood sugar levels can be detected by 3 days of age. By 3-6 weeks of age mice develop fasting hyperglycemia and become diabetic by 10 weeks. A reduced beta-cell mass can be detected by 4 weeks and a profound insulin resistance is observed in skeletal muscle and liver tissue by 6-8 weeks. Levels of fasting sugars continue to rise until male mice eventually succumb to dehydration and hyperosomolar coma. Female mice, while exhibiting a similar progression, tend not to die. This mutant mouse represents a model useful in studies related to type 2 diabetes. | ||

| This transgenic mouse strain overexpresses human nuclear sterol regulatory element binding protein-1c in adipose tissue under the control of the adipocyte-specific aP2 promoter. The phenotype of transgenic mice resembles congenital generalized lipodystrophy (CGL), a rare autosomal recessive disorder in humans. CGL is characterized by an insufficiency of adipose tissue which is evident at birth and is accompanied by a severe insulin resistance leading to symptoms of type II diabetes mellitis, (hyperinsulinemia and hyperglycemia), and an enlarged fatty liver. Transgenic mice exhibit these symptoms showing defects in differentiation of white fat accompanied by an hypertrophy of brown fat that resembles immature white fat. | ||

| Mice homozygous for the tubby spontaneous mutation experience maturity-onset obesity. Homozygous mutant mice are recognizable by increased body weight at 3 to 4 months in males and at 4 to 6 months in females. Both sexes are fertile. The increased weight is composed of excess adipose tissue. Blood glucose is normal, but plasma insulin is increased prior to obvious signs of obesity and may rise to 20 times normal by 6 months on the C57BL/6 background.

Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at 4 to 8 weeks. Homozygous mutant mice are polyphagic, polydipsic, and polyuric. The course of the disease is markedly influenced by genetic background. A number of features are observed on the C57BLKS background, including an uncontrolled rise in blood sugar, severe depletion of the insulin-producing beta-cells of the pancreatic islets, and death by 10 months of age. Exogenous insulin fails to control blood glucose levels and gluconeogenic enzyme activity increases. Peripheral neuropathy and myocardial disease are seen in C57BLKS Leprdb homozygotes.

| 001192 | BKS.Cg-meaJ Leprdb +/+ + m/J | Repository-Cryopreserved |
| Mice homozygous for the meander tail-J spontaneous mutation (meaJ) have variably shortened and kinked tails. At about 2 weeks an unsteadiness of gait, often amounting to a tremor, appears. Homozygous mutant mice are smaller and less vigorous than wiltype controls but are fertile. The anterior lobe of the cerebellum is disorganized. Purkinje cells are scattered, some cellular layers never form, and Bergmann glial processes are absent. The cytoarchitecture of the posterior lobe is normal, and the transition from normal to disorganized areas is sharply demarcated. This mutation occurred in the BKS.Cg-Leprdb +/+ m strain so it is also segregating for the diabetes (Leprdb) and misty (m) mutations.

Homozygous mutant mice increase in weight rapidly and may reach three times the normal weight of wildtype controls. In addition to obesity, mutant mice exhibit hyperphagia; a diabetes-like syndrome of hyperglycemia, glucose intolerance, and elevated plasma insulin; subfertility; and increased hormone production from both pituitary and adrenal. They are also hypometabolic and hypothermic. The obesity is characterized by both an increased 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 stimulati

| 002391 | BKSChpLt.HRS-Cpefat/J | Repository-Cryopreserved |
| Mice homozygous for the fat spontaneous mutation (Cpefat) on a C57BLKS/J genetic background (N10) have a diabetes phenotype that is primarily restricted to males and is more severe than what is seen on the original HRS/J or C57BLKS/J (N5) genetic backgrounds. At weaning both males and female homozygous mutant mice were significantly lighter than wildtype or heterozygous littermates. Obesity develops between 6 and 8 weeks of age and mutant mice can be distinguished from wildtype littermates between 8 and 12 weeks of age. By 18 weeks fat mutant mice will reach 45-55 g and may reach 60-70 g by 6 months of age. Thus, the obesity is thus slower to develop than in the obese (Lepob) and diabetes (Leprdb) mutant mice. The excess adiposity is distributed throughout the body's fat stores, in contrast to the largely axial and inguinal fat deposition of the obese and diabetes mutant mice. Hyperinsulinemia is severe by 4 weeks of age and contin

| 002110 | C3.SW/Lt-Chr YC3HeB/FeChp/J | Repository-Cryopreserved |
| C3.SW-H2b/SnJ (Stock number 000438) males exhibit maturity onset impairment of glucose tolerance and hyperinsulinemia. Transfer of the Y chromosome from the C3HeB/FeChp background into the C3.SW-H2b/SnJ background leads to a reduction in hyperinsulinemic and hyperglycemic stress on the pancreatic islets. This strain and Stock number 002111 demonstrate that the Y chromosome modulates the level of hyperinsulinemic and glycemic stress exerted upon pancreatic beta cells. | ||
| 002111 | C3.SW/Lt-Chr YSW/J | Repository-Cryopreserved |
| C3.SW-H2b/SnJ (Stock number 000438) males exhibit maturity onset impairment of glucose tolerance and hyperinsulinemia. In contrast to Stock number 002110, this strain carries the C3.SW-H2b/SnJ Y chromosome. Males develop extreme hyperinsulinemia, transiently elevated plasma glucose and extreme islet hyperplasia. This strain and Stock number 002110 demonstrate that the Y chromosome modulates the level of hyperinsulinemic and glycemic stress exerted upon pancreatic beta cells. | ||
| 003711 | CAST.B6-Tubtub/Jng | Repository-Cryopreserved |
| Mice homozygous for the tubby spontaneous mutation experience maturity-onset obesity. Homozygous mutant mice are recognizable by increased body weight at 3 to 4 months in males and at 4 to 6 months in females. Both sexes are fertile. The increased weight is composed of excess adipose tissue. Blood glucose is normal, but plasma insulin is increased prior to obvious signs of obesity and may rise to 20 times normal by 6 months on the C57BL/6 background. Despite elevated plasma total cholesterol, triglycerides, and high-density lipoprotein cholesterol, homozygous mutant mice do not exhibit atherosclerotic fatty streak blood vessel lesions. Tubby mutant mice also exhibit retinal degeneration, initially believed due to the presence of another mutation which was called rd5, but since demonstrated to be a pleiotropic effect of the Tubtub mutation (Ohlemiller et al., 1997); the retinal phenotype is moderated by a QTL on Chromosome 11 (Ikeda et al., 2002).

| 000707 | CBA.Cg-m Leprdb/+ +/J | Repository-Cryopreserved |
| Leprdb/Leprdb mice on the CBA strain background are characterized by exocrine pancreatic necrosis and kidney lesions in aging mice. In contrast to the obesity observed in other strain backgrounds, five month old homozygous males exhibit weight loss in comparison to controls. Homozygous males develop severe hyperglycemia exhibiting blood sugar levels of +/-475 mg/dl by three months of age and increasing to +/- 517 mg/dl by five months. Five month old homozygous males do not exhibit hyperinsulinemia, however homozygous females reach levels of +/-540 uU/ml. Homozygous males do not survive beyond six months. (Leiter EH, et al, 1981) Because of the sterility of Leprdb homozygotes, misty has been incorporated into stocks for maintenance of the diabetes mutation. The repulsion double heterozygote (Leprdb +/+ m) facilitates identification of heterozygotes for breeding, while the coupling double heterozygote,

| 004100 | FVB-Tg(AZIP/F)1Vsn/J | Repository-Cryopreserved |
| Mice expressing the A-ZIP/F gene under the control of 7.6kB of the adipocyte specific Fabp4 promoter have virtually no white adipose tissue and a reduced amount of brown adipose tissue. Brown adipose is found in lesser amounts as the animal ages. These mutant mice are very sensitive to cold temperature. Hemizygotes suffer from poor fecundity; the donating investigator indicates that not all males breed and pregnant females lactate inadequately. At birth, mice appear normal, losing weight in the first post-natal week but reach or exceed wildtype weight by 8-11 weeks. Adult mice display polyphagia and polydypsia, eating and drinking several times more than wildtype mice. Urine output is greatly increased. Transgenic mice have a characteristic rough-appearing coat and increased abdominal girth attributed to enlarged viscera. Most notably affected is the liver. Histological examination of liver tissue reveals numerous lipid droplets. Pancreatic islets are hypertrophic and hyperplast

| 002384 | FVB/N-Tg(UcpDta)1Kz/J | Repository-Cryopreserved |
| Transgenic mice fed a "Western diet" developed marked obesity, insulin resistance, hyperglycemia, and hyperlipidemia. Mice hemizygous for the TgN(UcpDta)1Kz transgene develop early obesity in the absence of hyperphagia indicating an increased metabolic efficiency. Hyperphagia does follow and is present in mice over 7 weeks of age. | ||
| 006846 | STOCK Leprdb-9J/Jgn | Repository-Cryopreserved |
| Mice homozygous for this mutation exhibit moderate obesity and extreme diabetes. The primary investigator reports blood glucose levels reaching 600-850 mg/ml and low plasma insulin levels (1-4 ng/ml). Pancreatic beta cells are small, degranulated and atrophic. The liver is steatotic and strongly PAS-positive for glycogen. Adrenal glands are large with a hyperplastic zona reticularis and appear to be missing the medulla. Homozygous females have fewer primary oocytes and follicles, as well as a decreased amount of developing and ovulated follices. Fecundity is decreased resulting in smaller litter sizes and fewer litters. | ||
