Availability: Live colony
Not genetically modified animal
In 2004, Dr. Masuyama and Dr. Shinohara (Research Laboratories of Torii Pharmaceutical Co., Ltd., Japan) established the congenic type 2 diabetes model Spontaneously Diabetic Torii fatty (SDT fatty) rat by introducing the fa allele of the Zucker Fatty rat into the genome of the original SDT rat 1). SDT fatty rats were introduced to Central Pharmaceutical Research Institute, Japan Tobacco Inc. (Japan) and were characterized in detail by Dr. Ohta and Dr. Sasase. CLEA Japan has received right of production and sales from Japan Tobacco Inc., and has distributed the animals as SDT fatty rats from 2012.
Model Highlights (from Study Data)
Key findings extracted from the detailed study reports are summarized below.
【Diabetic Nephropathy Model】
Rapid Diabetic Nephropathy Model in SDT Fatty Rats
10-week protocol showing >50% GFR decline and severe renal fibrosis, enabling fast evaluation of anti-diabetic nephropathy therapies.
▼ 10-week 0.3% salt load + unilateral nephrectomy in SDT fatty rats
Creatinine clearance decreased and GFR declined by more than 50%.
