Benefits

·Diet-induced obesity when fed a 60 kcal% high fat diet

·Pre-diabetic fed blood glucose levels with glucose intolerance by 8 weeks of age

·Improved glucose tolerance and insulin resistance when treated with Rosiglitazone

·Pancreatic beta cell hypertrophy without islet atrophy

·Hyperinsulinemia, hyperleptinemia, leptin resistance, and hypertension

·Moderate diet-induced obesity without hyperphagia when fed a 27 kcal% (10-11% wt/wt) fat diet

·Males transition from impared glucose tolerance to stable non-fasting hyperglycemia by 10 weeks of age

·Moderately elevated plasma insulin, islets transition from hypertrophy and hyperplasia to atrophy by 24 weeks

·Elevated leptin and triglycerides

·Moderate obesity in both males and females

·Males are normoglycemic at weaning, become glucose intolerant by 4 weeks, and begin developing hyperglycemia by 10-14 weeks of age

·Males are hyperinsulinemic, exhibiting plasma insulin levels between 8-12 ng/ml by 8 weeks of age

·Both sexes develop pancreatic islet hypertrophy and hyperplasia

·Males have severe dyslipidemia, with elevated triglycerides, total cholesterol, HDL cholesterol, and free fatty acids

Considerations

DIO appearance and care

·Mild glomerulosclerotic changes

· Males respond to high-dose Rosiglitazone with lower blood glucose and improved glucose  tolerance (The Jackson Laboratory, unpublished)

Benefits

· Hyperphagia with moderate obesity

·Early, severe hyperglycemia and glucose intolerance

·Hyperinsulinemia and insulin resistance, with islet hypertrophy and hyperplasia

·Elevated HbA1c and microalbuminuria

· Hyperphagic, leading to significant obesity by 6 weeks of age

· Male and female homozygotes become diabetic by 6 and 8 weeks of age, respectively

· Severe hyperglycemia, with fasting plasma glucose levels of 400 mg/dl by 10 weeks of age

· Progressive hypertriglyceridemia, with higher blood triglycerides in males

· Early hypersecretion of insulin, then islets atrophy and mice become hypoinsulinemic

· Moderate systemic hypertension and rapidly progressive diabetic nephropathy

· Hyperphagic , becoming obese by four weeks of age

· Glucose intolerance with severe hyperglycemia by 8 weeks of age and transient hyperinsulinemia

· Severe islet atrophy causing hypoinsulinemia and death by 10 months of age

· Polydipsic, polyuric, increased gluconeogenic enzyme activity and increased metabolic efficiency

Name & Stock Number

MSNASH/PcoJ (030888)

Common Name

MS-NASH

Benefits

·Has an intact leptin pathway (similar to the human disease )

·Exhibits spontaneous obesity, dyslipidemia, rapid insulin resistance, high level of insulin secretion as hypersulinemia

·Develops liver steatosis leading to NAFLD/NASH

·Responds to anti-diabetic standard of care treatments e.g. Semaglutide (Ozempic®) that results in a reduction of body weight, food intake, and blood glucose levels

Considerations

Females do not exhibit the diabetic phenotype
