  • A non-obese model of Non-Insulin Dependent Diabetes Mellitus (NIDDM), type II diabetes.
  • It exhibits similar metabolic, hormonal, and vascular disorders to the human diabetes disease.
  • Males develop type II diabetes at approximately 14 - 16 weeks of age.
  • Characteristics include fasting hyperglycemia, impaired secretion of insulin in response to glucose both in vivo and in isolated pancreatic cells, hepatic and peripheral insulin resistance and polyuria
  • Late complications such as retinopathy, microangiopathy, neuropathy, and nephropathy have been described in literature
  • Phenotypes, particularly blood glucose, are diet dependent and we recommend feeding NIH31-M.
  • The GK colony was derived from inbred stock and is bred randomly in a closed colony.

Origin:

The Goto-Kakizaki inbred model was developed by Tohoku University in 1975. Aarhus University Hospital in Denmark received stock in 1994. M&B A/S (now Taconic Europe) received stock from Aarhus in 1997. The rats were derived by embryo transfer in 2005 at Taconic US.
