Genetic mice models of type 2 diabetes for evaluation of the effectiveness of minor biologically active food substances

Abstract

This report is devoted to discussion of type 2 diabetes experimental modelling on genetic mice lines. These laboratory animals, the same as genetic rats lines, are usually used in type 2 diabetes experimental modelling. The problem of using mice with genetic obesity in modeling of type 2 diabetes is discussed in details in the review. In this article the authors shortly characterize the congenic line of mice ККАУ, suffering from genetic obesity and hyperinsulinemia. The features of modelling type 2 diabetes using ob/ob and db/db mice are described closely. The phenotype of the animals comes into obesity, infertility, brakes in length growth, hyperinsulinemia and dysimmunity. Neither leptin mRNA, nor the hormone itself are synthesized in ob/ob mice, leading to ob phenotype formation. Whilst db/db mice have two mutant copies of leptin receptor gene, which leads to gradual hyperglycemia and obesity progression, followed by hyperinsulemia similar to human type 2 diabetes. C57BL/KsLeprdb/+ mice with recessive gene leptin receptoi-Lepiнlb (db) is very perspective genetic type 2 diabetes model developed in Russia. TSOD mice are used as an alternative model (Tsumura Suzuki, diabetes with obesity), showing diabetes and obesity symptoms with marked hyperinsulinemia and pancreatic gland hypertrophy. Thus, presented in this review scientific reports approve wide opportunities of effective usage of genetic lines of small laboratory animals (mice) for type 2 diabetes modelling.
