Abstract:
Objective:To study the effect of quercetin given during pregnancy and lactation period of obese rats on weight and expression of insulin-like growth factors-1 ( IGF-1 ) mRNA of the offspring . Methods:In the study , 8 healthy weaning female SD rats were randomly selected to feed the basal diet and as blank control group , and the others were fed with high-fat diet.When the average weight of the high-fat diet rats was 20% as many as the average weight of the control group , we believed the model succeeded .Then the female SD rats were mated and the pregnant rats were randomly divided into 5 groups , 8 rats in each .They were fed with high fat diet during pregnancy and lactation , and the obese pregnant rats were respectively irrigated with 0 mg/kg body weight ( high-fat control ) , 50 mg/kg body weight,100 mg/kg body weight , and 200 mg/kg body weight quercetin .The blank control group was fed with basic diet throughout the experimental period .The birth weight , the weights during the development of d7, d21, d56, and d98, and the expressions of IGF-1 mRNA in livers tissue of the F1 generation were measured.Results:The average birth weight of the F1 generation of high fat diet (HFD) group was sig-nificantly higher than that of the blank control group .Decreased offspring birth weight was observed with the intervention of quercetin , which effect remained to the delectation .The quercetin also reduced the ex-pression of IGF-1 mRNA in livers of the F1 generation , and this effect remained to the adulthood .The 200 mg/kg body weight quercetin was most significantly effective .Conclusion:The averaged birth weight of the F1 generation of obese pregnant rats was significantly increased , and quercetin could effectively in-hibit the expression of IGF-1 mRNA in livers of F1 generation to decrease cell proliferation and cell differentiation.
