Abstract

Endometriosis is frequent in women of childbearing age with a morbidity rate of approximately 10%. Its clinical features mainly manifest as dysmenorrhea, chronic pelvic pain, and infertility. However, effective treatments are still lacking; hence, it is necessary to identify an effective and safe treatment strategy on endometriosis. Moutan Cortex extract (MCE) was prepared by decoction. Then, cell proliferation and apoptosis in human endometrial stromal cells (HESCs) were detected by cell counting kit-8, EdU cell proliferation assay, and flow cytometry. Wound-healing assay and transwell migration assay were performed to explore cell migration or invasion. The expression of indicators of downstream signaling pathways was determined by Western blot analysis or enzyme-linked-immunosorbent serologic assay. MCE treatment inhibited cell viability and proliferation in HESCs while promoting cell apoptosis. MCE reduced migration and invasion of HESCs. Furthermore, MCE inhibited osteopontin-induced, mitogen-activated, protein kinase (MAPK)-mediated matrix metallopeptidase 9 (MMP9) activation, and upregulation of OPN reversed the effect of MCE on HESCs. In this study, MCE inhibited the proliferation and migration of endometrial stromal cells by inhibiting OPN induced, MAPK-mediated MMP9 activation. MCE might be a novel treatment strategy on endometriosis.

牡丹皮提取物通过抑制opn诱导的、mapk介导的MMP9激活来抑制子宫内膜基质细胞的增殖和迁移
子宫内膜异位症常见于育龄妇女,发病率约为10%。其临床特征主要表现为痛经、慢性盆腔疼痛、不孕症。然而,仍然缺乏有效的治疗方法;因此,有必要确定一个有效和安全的治疗策略子宫内膜异位症。采用煎法制备牡丹皮提取物(MCE)。采用细胞计数试剂盒-8、EdU细胞增殖试验和流式细胞术检测人子宫内膜基质细胞(HESCs)的增殖和凋亡情况。创面愈合试验和跨井迁移试验探讨细胞迁移或侵袭。通过Western blot分析或酶联免疫吸附血清学检测下游信号通路指标的表达。MCE处理抑制HESCs细胞活力和增殖,促进细胞凋亡。MCE减少HESCs的迁移和侵袭。此外,MCE抑制骨桥蛋白诱导的、丝裂原激活的、蛋白激酶(MAPK)介导的基质金属肽酶9 (MMP9)的激活,上调OPN可逆转MCE对HESCs的影响。在本研究中,MCE通过抑制OPN诱导的、mapk介导的MMP9激活来抑制子宫内膜基质细胞的增殖和迁移。MCE可能是子宫内膜异位症的一种新的治疗策略。
