Objective:To explore the effect of curcuminon the insulin receptor substrate1(IRS1)/phosphatidylinositol-3-kinase(PI3K)/endometrial expression of glucose 4(GLUT4)signalling pathway and its regulator,phosphatase and tensin homolog(PTEN),in a rat model of polycystic ovarian syndrome(PCOS).Methods:PcoS model was induced by letrozole intragastric ***-Dawleyrats were randomized into 4groups according to a random number table:(1)control group;(2)PcoS group,which was subjected to PCOS and received vehicle;(3)curcumin group,which was subjected to PCoS and treated with curcumin(200 mg/kg for 2 weeks);and(4)curcumin+LY294002 group,which was subjected to PCOS,and treated with curcumin and LY294002(a specific PI3K inhibitor).Serum hormone levels(17β-estradiol,follicle stimulating hormone,luteinizinghormone,progesterone,and testosterone)were measured by enzyme linked immunosorbentassay,and insulin resistance(IR)was assessed using the homeostasismodel assessment of *** tissues were stained with haematoxylin and eosin for pathological and apoptosis *** levels of key transcriptional regulators and downstream targets,including IRS1,Pl3K,protein kinase B(AKT),GLUT4,and PTEN,were measured via reverse transcription polymerase chain reaction and Western blot,***:The Pcos group showed impaired ovarian morphology and *** with the PCoS group,curcumin treatment exerted ovarioprotective effects,down-regulated serum testosterone,restored IR,inhibited inflammatory cell infiltration in ovarian tissues,decreased IRS1,PI3K,and AKT expressions,and up-regulated GLUT4 and PTEN expressions in PCOS rats(P0.05).Conclusion:The beneficial effects of curcumin on PCOS rats included the alteration of serum hormone levels and recovery of morphological ovarian lesions,in which,PTEN,a new target
