目的 探讨减味寿胎丸(JSP)对自然流产(SA)的影响,并探究其是否通过抑制滋养细胞摄取外泌体miR-410-3p(Exo-miR-410-3p)并促进上皮间充质转化(EMT)、迁移及侵袭发挥作用。 方法 通过电穿孔方法将miR-410-3p模拟物装载入牛奶外泌体以制备Exo-miR-410-3p,通过透射电子显微镜、纳米颗粒追踪分析和Western blotting等方法检测Exo-miR-410-3p的表征。制备对照血清或JSP含药血清。分别设置对照组:HTR-8/Svneo正常培养;Exo-miR-410-3p组:HTR-8/Svneo+Exo-miR-410-3p;Exo-miR-410-3p+对照血清组:HTR-8/Svneo+Exo-miR-410-3p+对照血清;Exo-miR-410-3p+JSP含药血清组:HTR-8/Svneo+Exo-miR-410-3p+JSP含药血清。通过RT-qPCR、Western blotting和免疫荧光染色检测相关表达差异。分别通过CCK-8实验、划痕实验和Transwell实验评估HTR-8/Svneo细胞增殖、迁移及侵袭能力。对荧光标记外泌体进行体内和体外成像追踪,并计算孕鼠胚胎吸收率。通过RT-qPCR、Western blotting、原位杂交和免疫组化行表达差异的体内验证。 结果 划痕实验和Transwell实验显示,与对照组相比,Exo-miR-410-3p组HTR-8/Svneo细胞迁移和侵袭能力减弱(P<0.01),而JSP含药血清可逆转HTR-8/Svneo细胞减弱的迁移和侵袭能力。体内实验证实,JSP含药血清可抑制Exo-miR-410-3p到达母胎界面,与Exo-miR-410-3p组相比,Exo-miR-410-3p+JSP组胚胎吸收率更低(P<0.01)。JSP含药血清降低SA小鼠体内miR-410-3p的水平(P<0.05),同时上调TRAF6的表达。 结论 JSP可能通过抑制滋养层细胞摄取Exo-miR-410-3p,促进SA中滋养层细胞EMT、迁移及侵袭,减少胚胎流产。
