Expression of Advanced Glycation End Products in a Rat Model of Polycystic Ovarian Syndrome / 中国医科大学学报

ABSTRACT

Objective To investigate the expression of advanced glycation end products(AGEs)in a rat model of polycystic ovarian syndrome (PCOS)induced by dehydroepiandrosterone. Methods The PCOS rat model was established using dehydroepiandrosterone . After confirming that the model rats were set up successfully,serum AGEs concentrations were measured using competitive ELISA and the expression of AGEs in the ovarian tissues of these rats was detected using immunohistochemistry. Results The serum AGEs level in the experimental group were signifi?cantly higher than that in the control group(P<0.05). Furthermore,AGEs expression were significantly higher in the experimental group than in the control group(P<0.01). Conclusion AGEs are highly expressed in the rat PCOS model,signifying their importance in the diagnosis and pathogenesis of PCOS.
