| 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 four weeks of age. Homozygous mutant mice gain weight rapidly and may reach three times the normal weight of wild-type 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 ab

| 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. Steroid sulfotransferase enzymes, aberrantly expressed in diabet

| 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. | ||
