db/db mice (JAX™); BKS.Cg-Dock7m+/+Leprdb/J

Code 249801
Due to the symptoms of obesitas, insulin resistance and hyperinsulinemia db/db mice are recognized as a model of type II diabetes. Also a suitable model for the study of diabetic neuropathology and nephropathy.

Nomenclature: BKS.Cg-Dock7m +/+ Leprdb/J

Type: Inbred mice

Origin: Spontaneous mutation on the congenic C57BLKS/J. The diabetic mutation results from a point mutation in the gene of leptin receptor Lepr. Bred. In Charles River since May 2002 under license and breeding standard of The Jackson Laboratory.

db/db mice are used to model phase 1 to 3 of diabetes type II and obesity. Mice that are homozygous for the diabetes spontaneous mutation (Leprdb) demonstrate morbid obesity, chronic hyperglycemia, pancreatic beta cell atrophy and come to be hypoinsulinemic. Affected mice are polyphagic, polydipsic, and polyuric. Obesity begins at three to four weeks of age. The BKS background brings an uncontrolled rise in blood sugar, severe depletion of insulin-producing beta-cells of the pancreatic islets, peripheral neuropathy, myocardial disease and death by ten months. Exogenous insulin results in loss of control of blood glucose levels, while gluconeogenic enzyme activity increases. Metabolic efficiency is increased, while wound healing is postponed. 

Coat color: Black

Strain code: 607

Ideal for: Phase I, II, and III type 2 diabetes, obesity research, wound healing
