Exploration on the Intervention Mechanism of Bushen Zhupai Decoction on Polycystic Ovary Syndrome Rats with Insulin Resistance Based on IL-6/PI3K/AKT Signaling Pathway
摘要
Abstract
Objective To investigate the intervention mechanism of Bushen Zhupai Decoction on polycystic ovary syndrome rats with insulin resistance based on IL-6/PI3K/AKT signaling pathway Methods A rat model of polycystic ovary syndrome with insulin resistance was established by feeding high-fat diet combined with oral administration of letrozole,and the blank group was fed with ordinary diet.The modeled rats were randomly divided into model group,metformin group and Bushen Zhupai Decoction low-,medium-and high-dosage groups.The corresponding intervention were given for 28 days.Fasting blood glucose(FBG)content was detected,and insulin resistance index(HOMA-IR)was calculated.ELISA was used to detect serum fasting insulin(FINS),testosterone(T),estradiol(E2),luteinizing hormone(LH)and follicle stimulating hormone(FSH)contents.HE staining was used to observe the morphology of ovarian tissue.Immunohistochemistry was used to detected the expressions of interleukin(IL)-6,p-PI3K,p-AKT and GLUT4 in ovarian tissue.Western blot was used to detect the protein expressions of IL-6,PI3K,p-PI3K,AKT,p-AKT and GLUT4 in ovarian tissue,while RT-PCR was used to detect the mRNA expressions of IL-6,PI3K,AKT and GLUT4.Results Compared with the blank group,the body mass,FBG,FINS and serum T and LH contents of the model group rats significantly increased(P<0.01),while the serum E2 and FSH contents significantly decreased(P<0.01);ovarian tissue showed polycystic changes,with reduced layers and loose arrangement of granulosa cells,the expression of IL-6 protein and mRNA in ovarian tissue significantly increased(P<0.01),the expressions of p-PI3K,p-AKT and GLUT4 proteins significantly decreased(P<0.01),and the expressions of PI3K,AKT and GLUT4 mRNA significantly decreased(P<0.01).Compared with the model group,the body mass of rats in each administration group decreased,and the contents of FBG,FINS and serum T and LH decreased(P<0.01,P<0.05),while the contents of E2 and FSH increased;polycystic changes in ovarian tissue were reduced,mature follicles increased,and granulosa cells were tightly arranged,the expression of IL-6 protein and mRNA in ovarian tissue decreased,the expressions of p-PI3K,p-AKT,GLUT4 protein and PI3K,AKT,GLUT4 mRNA increased.Bushen Zhupai Decoction high-dosage group showed statistical significance(P<0.01).Conclusion Bushen Zhupai Decoction can improve reproductive and metabolic disorders in polycystic ovary syndrome with insulin resistance rats,and its mechanism may be related to inhibiting IL-6 expression,activating the PI3K/AKT signaling pathway,and alleviating insulin resistance.关键词
