| Abstract: | AIM: To observe the effects of Shaofu-Zhuyu decoction (SFZY) on mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway in the rats with endometriosis (EM), and to explore the mechanism of SFZY for treatment of EM.METHODS: Healthy female SD rats were used to establish the EM model. The rats were randomly divided into blank control group, model group, positive control group, and low dose, middle dose and high dose of SFZY groups. The pathological changes of the endometriotic tissue were observed by HE staining. The levels of tumor necrosis factor-α (TNF-α), interleukin-6(IL-6) and IL-8 in the uterine tissue were detected by ELISA. The mRNA expression of ERK, vascular endothelial growh factor (VEGF) and matrix metalloprotein-9 (MMP-9) was detected by RT-qPCR. The protein expression of nuclear factor-κB (NF-κB), MAPK and MAPK-ERK kinase (MEK) was determined by Western blot.RESULTS: Compared with model group, the levels of TNF-α, IL-6 and IL-8 in the uterine tissue of the rats in middle dose and high dose of SFZY groups were significantly decreased (P<0.05), the mRNA expression of ERK, VEGF and MMP-9 was significantly reduced, and the protein expression of NF-κB, MEK and MAPK was decreased significantly in the rat endometriotic tissues (P<0.05).CONCLUSION: SFZY may play a key role in the treatment of EM by regulating MAPK/ERK signaling pathway. |
