Abstract:
Objective To use the ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)to authenticate the chemical composition of Morinda citrifolia,and further experiments verify that Morinda citrifolia regulate miR-223-3p/NLRP3 signaling pathway to inhibit the inflammatory response in rats with polycystic ovary syndrome(PCOS).Methods Use UPLC-MS/MS analyze the chemical composition of Morinda citrifolia.SD female rats were randomly divided into three groups:normal control group(n=5),PCOS model group(n=5)and Morinda citrifolia gavage group(n=5).HE staining observe the morphology of ovarian histology,ELISA method detect the expression levels of testosterone(T),luteinizing hormone(LH),follicle stimulating hormone(FSH),interleukin(IL)-1βand IL-18,RT-qPCR detect the mRNA expression of miR-223-3p and NLRP3,and Western blot detect the protein expression of NLRP3.Results UPLC-MS/MS identify 641 chemical composition of Morinda citrifolia,including luteolin,Apigenin,emodin and other composition.Compared with the normal control group,the number of cell layers of ovarian granule in the PCOS model group is reduced,and follicular cystic dilation,atresia follicles increased,T and LH levels increased(P<0.05),FSH levels decreased(P<0.05),IL-18 and IL-1β levels increased(P<0.05),and ovarian tissue miR-223-3p mRNA expression decreased(P<0.01),NLRP3 mRNA and protein expression increased(P<0.01)in PCOS model group.Compared with the PCOS model group,the proportion of follicles at all levels is normal,the number of granule cell layers increased,T and LH levels decreased(P<0.05),FSH levels increased(P<0.05),IL-18 and IL-1β levels decreased(P<0.05),miR-223-3p mRNA expression in ovarian tissue increased((P<0.05),NLRP3 mRNA and protein expression decreased(P<0.05)in Morinda citrifolia gavage group.Conclusion Morinda citrifolia can improve the ovary pathological state of PCOS rats,change the abnormal sex hormones and reduce the levels of inflammatory factors IL-18 and IL-1β.The mechanism maybe regulate the miR-223-3p/NLRP3 signaling pathway to inhibit the inflammatory response in PCOS rats.
