Abstract:
Objective To examine the circulating glucose and body weight in the transgenic MKR mouse model who expressed dominant-negative IGF-1 receptor and insulin receptor in skeletal muscle leading to systemic insulin resistance and diabetes. Methods MKR mice were genotyped by PCR analysis of tail DNA.And in these mice we examined the circulating glucose and body weight once a week from 1 to 16 weeks of age, and the circulating insulin and glucose tolerance at age of two-month-old by using C57 mice as controls. Results The descendents of MKR mice kept hereditary feature. And these mice had hyperglycaemia from 3 weeks of age,and an increasing body weight slowly(P
