JAX

ob/ob mice (JAX™); B6.Cg-Lepob/J

Code 24980140-164
Well characterized model of obesity. In addition to obesity, mutant mice exhibit hyperphagia, a diabetes-like syndrome of hyperglycemia and glucose intolerance.

Features

Nomenclature: B6.Cg-Lepob/J

Type: Inbred mice

Origin: The obese mutation, ob, arose spontaneously in strain V/Le at The Jackson Laboratory, Bar Harbor, Maine in 1949, and has been backcrossed to C57BL/6J for more than 45 generations.

Also known as B6 ob, these animals are homozygous for the obese spontaneous mutation, Lepob (often referred to as ob or ob/ob), show obesity, hyperphagia, transient hyperglycemia, glucose intolerance, and elevated plasma insulin. Ob/ob mice are also hypometabolic, hypothermic, and often subfertile. Hormone production from both pituitary and adrenal glands is increased, and wound healing is impaired. Ob/ob mice are commonly used to model phases 1 and 2 of diabetes type II, as well as obesity. The obesity is characterized by a growth in the number and size of adipocytes. Although hyperphagia furthers the obesity, homozygotes gain weight and deposit surplus fat even when restricted to a diet sufficient for normal weight maintenance in lean mice.

Coat color: Black

Strain code: 606

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