ABSTRACT
Objective:
To investigate the effects of green tea polysaccharides (TPs) on glucose metabolism and the activity of peroxisome proliferator-activated receptor gamma (PPAR-?) in KKAy type 2 diabetic mice.Methods:
Glucose tolerance test, fasting and postprandial glucose, gluconeogenesis, and insulin sensitivity were investigated in type 2 diabetic mice with orally administered TPs at the dose of 500mg/kg for 4-10 w. Effect of TPs on activity of PPAR-? was tested in vitro.Results:
TPs could not only improve glucose tolerance, but also reduce fasting and postprandial blood glucose. In addition, TPs could inhibit gluconeogenesis and enhance insulin sensitivity in KKAy diabetic mice. TPs had also an effect of activating of PPAR-? with dose-response.Conclusion:
TPs have beneficial effect of lowering blood glucose in KKAy type 2 diabetic mice, which may be induced by enhancing insulin sensitivity by activating of PPAR-?.
