Non-hormonal therapeutic strategies for endometriosis are needed. The aim of this study was to characterize the effects of prostaglandin (PG)E2 receptor inhibitors to explore their potential as novel therapeutic strategies for endometriosis. The expression of PGE2 receptors (EP2 and EP4) in donated tissues from human ovarian endometriosis, adenomyosis and peritoneal endometriosis was examined using immunohistochemistry. Human endometriotic stromal cells (ESC) isolated from ovarian endometriotic tissue and peritoneal macrophages were treated with EP2 and EP4 antagonists. cAMP accumulation and the effect of EP antagonists were measured using cAMP assays. DNA synthesis in ESC was detected using bromodeoxyuridine incorporation analysis. Interleukin (IL)-6 and IL-8 protein levels in ESC supernatants were measured using ELISAs. mRNA expression level for aromatase by ESC, and selected cytokines by peritoneal macrophages was measured using RT–PCR. EP2 and EP4 receptors were expressed in cells derived from control and diseased tissue, ovarian endometriotic, adenomyotic and peritoneal lesions. A selective EP2 antagonist reduced DNA synthesis, cAMP accumulation and IL-1β-induced proinflammatory cytokine secretion and aromatase expression. A selective EP4 antagonist negated IL-1β-induced IL-6 secretion and aromatase expression. In peritoneal macrophages, EP expression was elevated in endometriosis samples but the EP4 antagonist reduced cAMP levels and expression of vascular endothelial growth factor, chemokine ligand 2 and chemokine ligand 3 mRNA. EP2 and EP4 are functioning in endometriosis lesions and peritoneal macrophages, and their selective antagonists can reduce EP-mediated actions, therefore, the EP antagonists are potential therapeutic agents for controlling endometriosis.

选择性 PGE2 受体拮抗剂对人子宫内膜异位基质细胞和腹膜巨噬细胞的应用

需要针对子宫内膜异位症的非激素治疗策略。本研究的目的是表征前列腺素 (PG)E 2受体抑制剂的作用,以探索其作为子宫内膜异位症新治疗策略的潜力。PGE 2的表达使用免疫组织化学检查来自人卵巢子宫内膜异位症、子宫腺肌病和腹膜子宫内膜异位症的捐赠组织中的 EP2 和 EP4 受体。从卵巢子宫内膜异位组织和腹膜巨噬细胞中分离出的人子宫内膜异位基质细胞 (ESC) 用 EP2 和 EP4 拮抗剂处理。使用 cAMP 测定法测量 cAMP 积累和 EP 拮抗剂的作用。使用溴脱氧尿苷掺入分析检测 ESC 中的 DNA 合成。使用 ELISA 测量 ESC 上清液中的白细胞介素 (IL)-6 和 IL-8 蛋白水平。使用 RT-PCR 测量 ESC 芳香化酶的 mRNA 表达水平,以及腹腔巨噬细胞选择的细胞因子。EP2 和 EP4 受体在来自对照和患病组织、卵巢子宫内膜异位症、子宫腺肌症和腹膜病变的细胞中表达。选择性 EP2 拮抗剂减少 DNA 合成、cAMP 积累和 IL-1β 诱导的促炎细胞因子分泌和芳香酶表达。选择性 EP4 拮抗剂可抑制 IL-1β 诱导的 IL-6 分泌和芳香酶表达。在腹膜巨噬细胞中,EP 表达在子宫内膜异位症样本中升高,但 EP4 拮抗剂降低了 cAMP 水平和血管内皮生长因子、趋化因子配体 2 和趋化因子配体 3 mRNA 的表达。EP2和EP4在子宫内膜异位症病变和腹膜巨噬细胞中起作用,它们的选择性拮抗剂可以减少EP介导的作用,因此,EP拮抗剂是控制子宫内膜异位症的潜在治疗剂。选择性 EP4 拮抗剂可抑制 IL-1β 诱导的 IL-6 分泌和芳香酶表达。在腹膜巨噬细胞中,EP 表达在子宫内膜异位症样本中升高,但 EP4 拮抗剂降低了 cAMP 水平和血管内皮生长因子、趋化因子配体 2 和趋化因子配体 3 mRNA 的表达。EP2和EP4在子宫内膜异位症病变和腹膜巨噬细胞中起作用,它们的选择性拮抗剂可以减少EP介导的作用,因此,EP拮抗剂是控制子宫内膜异位症的潜在治疗剂。选择性 EP4 拮抗剂可抑制 IL-1β 诱导的 IL-6 分泌和芳香酶表达。在腹膜巨噬细胞中,EP 表达在子宫内膜异位症样本中升高,但 EP4 拮抗剂降低了 cAMP 水平和血管内皮生长因子、趋化因子配体 2 和趋化因子配体 3 mRNA 的表达。EP2和EP4在子宫内膜异位症病变和腹膜巨噬细胞中起作用,它们的选择性拮抗剂可以减少EP介导的作用,因此,EP拮抗剂是控制子宫内膜异位症的潜在治疗剂。
