Summary

Data Summary

Official Name	BKS.Cg-Dock7^m +/+ Lepr^db
Common Name	BKS.Cg-m Lepr^db/+ +
Description	Mice homozygous for the diabetes spontaneous mutation (Leprdb) become identifiably obese around three to four weeks of age. Elevations of plasma insulin begin at 10 to 14 days and of blood sugar at four to eight 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. 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 diabetic mice, interact with the Leprdb mutation as modifiers of gender differences in obesity-induced diabetes susceptibility. Because of the sterility of Leprdb homozygotes, misty has been incorporated into stocks for maintenance of the diabetes mutation. The repulsion double heterozygote (Leprdb +/+ Dock7m) facilitates identification of heterozygotes for breeding, while the coupling double heterozygote, (Leprdb Dock7m/+ +) allows identification of homozygotes before the onset of clinical symptoms.

Scholarly citation norms must be followed for content reuse. Please acknowledge the MMPC-Live using the following text: 'The MMPC-Live data used in this manuscript was supported by the NIDDK National Mouse Metabolic Phenotyping Centers (MMPC-Live, RRID:SCR_008997, www.mmpc.org)'.

Please note that the acknowledgment text includes a Research Resource Identifier (RRID) for the MMPC-Live CU and Centers. Reproducibility is one of the corner stones of effective, open and transparent biomedical published research. However, too often, resources (e.g. model organisms, antibodies, and tools) are not reported with adequate detail to ensure others can replicate or expand upon the published results. The Research Resource Identification Initiative (#RII) seeks to change these limitations in reporting by the use of unique Research Resource Identifiers (RRIDs). This initiative is designed to encourage authors to provide identification of the types of resources used in their research by adding a globally unique accession number to the resources described in the their manuscripts. These identifiers, called RRIDs, will allow authors to cite the resources that they use in their manuscripts. RRIDs allow for easy tracking of all papers that have used the same resource making it easy to access how the same resources works in other scenarios.

It is expected that MMPC-Live users follow scholarly citation norms, giving credit to fellow scholars when accessing/using protocols and data, including data derived by MMPC-Live (such as summary data) and any plots, tables or screenshots depicting those data.

It is possible for invalid or incomplete results to be presented on the MMPC-Live web site due to software bugs, data problems, or artifacts of human error. Data sets are not necessarily static; we reserve the right to post corrections and updates as needed.

Prohibited use. Data contributors and data users may not use MMPC-Live in any unlawful manner, or in any manner that could impair MMPC-Live services, security or functionality.
