Transcription factors FoxO1 and FoxO3a expression on muscle and liver adipose tissue of KKAy diabetic mice / 基础医学与临床

ABSTRACT

Objective To detect the expression of FoxO1 and FoxO3a in liver and muscle tissue from KKAy diabetic mice.Methods Study group consists of 7 KKAy diabetic mice until 12 weeks,thereafter fed high fat diet for 4 weeks.It was diagnosed as diabetes when blood glucose was more than(16.7 mmol/L) in two consequent weeks.Control group consists of 7 C57BL mice 16 week old.Dispatched the mice and took quadriceps of femoris muscle and liver tissue to detect the FoxO1 and FoxO3a protein expression by Western blot with antibody.Results Liver and muscle FoxO1 expression was higher in KKAy diabetic mice than that in C57BL mice.FoxO3a expression was much higher in liver than in muscle in both groups.Muscle FoxO3a expression was higher in KKAy diabetic mice than that in control mice.Conclusion FoxO1 and FoxO3a in liver and muscle expressed differently in diabetic mice and control mice.They may play a role in mechanisms of insulin resistance and type 2 diabetes mellitus.
