9 Female ZDF rats with fa / fa -genotype similarly become obese and insulin-resistant, but do not progress to hyperglycaemia, except when fed … In our ZF rat colony, we incidentally found fa/fa homozygous male rats having repr… Please enable it to take advantage of the complete set of features! We discuss the diabetic features and complications found in ZDF rats and why these animals are widely used as a genetic model for obese type 2 diabetes. The Zucker fatty (ZF) rat harboring a missense mutation (fatty, fa) in the leptin receptor gene (Lepr) develops obesity without diabetes; Zucker diabetic fatty (ZDF) rats derived from the ZF strain exhibit obesity with diabetes and are widely used for research on type 2 diabetes (T2D). 2020 Mar 9;10(1):90. doi: 10.1038/s41398-020-0767-0.

Portal milieu and the interplay of multiple antidiabetic effects after gastric bypass surgery. Hepatic Transcriptome Analysis Revealing the Molecular Pathogenesis of Type 2 Diabetes Mellitus in Zucker Diabetic Fatty Rats. Male and female obese Zucker rats (OZR) were used as a model of Type 2 diabetes, and OZR fed a high isoflavone soy protein diet displayed improvements in lipid metabolism consistent with results in humans treated with antidiabetic PPAR agonists such as the fibrates or Fatty males were more frequently affected than fatty females. Turkenkopf IJ, Kava RA, Feldweg A, Horowitz C, Greenwood MR, Johnson PR. HHS A breeding program yielded a genetic pattern of diabetes consistent with a dominant gene not closely linked to the fatty gene.

Percentage body fat and plasma triglyceride values were decreased in fatty diabetic rats relative to control fatty rats, however, consistent with insulin resistance in fat and liver. 1- Characterization of STZ-Induced Type 2 Diabetes in Zucker Fatty Rats. vol. Some of these strains, such as most fatty Zucker rat colonies, are typically nondiabetic. A number of laboratories, including our own, have used obese Zucker and ZDF rats to investigate the consequences of insulin resistance and Type 2 diabetes on cardiac function ( 9 , 30 , 31 ). eCollection 2019 Sep. Am J Physiol Gastrointest Liver Physiol. Namely, these rats are obese and develop progressive insulin resistance, glucose intolerance, hyperinsulinemia, and hyperlipidemia (15 – 17). Epub 2011 Nov 1. 2019 May 1;316(5):G668-G678. Around 9% of the adult population in the world (463 million) suffer from diabetes mellitus.  |  Furthermore, cocoa rich-diets modify the intestinal microbiota composition both in humans and rats in healthy conditions. Circulating Agonist Autoantibody to 5-Hydroxytryptamine 2A Receptor in Lean and Diabetic Fatty Zucker Rat Strains. ZDF Rat (Obese fa/fa) Details. 1998 Dec;125(8):1708-14. doi: 10.1038/sj.bjp.0702245. Effects of prolonged type 2 diabetes on mitochondrial function in cerebral blood vessels. Goh TT, Mason TM, Gupta N, So A, Lam TK, Lam L, Lewis GF, Mari A, Giacca A. 2- Low dose streptozotocin (STZ) combined with high energy intake can effectively induce type 2 diabetes Male Zucker diabetic fatty fa/fa (ZDF) rats develop obesity and insulin resistance at a young age, and then with aging, progressively develop hyperglycemia. 1988 Nov;37(11):1549-58. doi: 10.2337/diab.37.11.1549. The content of pancreatic insulin was markedly decreased in the diabetic fatty rat relative to either the ad libitum or diet-restricted fatty rats. 1991 Oct;261(4 Pt 2):R912-9. Defective augmentation of glucose phosphorylation in response to a rise in plasma glucose in ZDF rats was associated with the coresidency of GKRP with GK in the cytoplasm in the midstage of diabetes, which was followed by a decrease in GK protein levels due to impaired posttranscriptional processing in the late stage of diabetes.
