Molecular mechanism of Shaofu Zhuyu decoction in treating endometriosis dysmenorrhea based on GPER2/MAPK/STAT1 axis / 中国中药杂志

ABSTRACT

The aim of this paper is to study the molecular mechanism of Shaofu Zhuyu decoction in treating dysmenorrhea of endometriosis based on GPER2/MAPK/STAT1 axis. In this study, HE staining was used to observe the pathological changes of the rats in each group. The levels of TNF-α and IL-6 were detected by ELISA assay. The mRNA expressions of neurotransmitter receptor (NK1) and GPER were detected by qPCR. The protein contents of MAPK and STAT1 were detected by Western blot. According to the results, compared with the model group, Shaofu Zhuyu decoction could significantly improve the inflammation of the ectopic uterine cavity tissue, decrease the contents of TNF-α and IL-6 in the uterine cavity, the mRNA expressions of NK1 and GPER, and the protein expressions of MAPK and STAT1. In conclusion, Shaofu Zhuyu decoction could effectively inhibit the expressions of GPER2, MAPK and STAT1, decrease the levels of TNF-α, IL-6 and NK1 mRNA and relieve the inflammatory pain in patients with endometriosis.
