Key Points

  • The main aim is to investigate how Shenggu Zaizao Pill affects pyroptosis in BMSCs, particularly in relation to NLRP3 transport regulated by dynein.
  • Divided BMSCs into control and various treatment groups including Shenggu Zaizao Pill.
  • Assessed cell viability using CCK8 and apoptosis through flow cytometry.
  • Measured protein expression of dynein, NLRP3, caspase-1, and GSDMD via Western blot.
  • Dexamethasone + LPS group showed decreased viability and increased apoptosis, along with elevated protein levels of dynein, NLRP3, caspase-1, and GSDMD.
  • Treatment with Dynarrestin and Shenggu Zaizao Pill improved cell viability and reduced apoptosis, leading to decreased levels of inflammation markers IL-1β and IL-18.

Abstract

目的 探索生骨再造丸对治疗激素性股骨头坏死(SANFH)的关键环节和作用机制,探寻SANFH发病机制与Dynein调控NLRP3炎性小体的关系以及阐明生骨再造丸治疗SANFH的作用靶点,完善生骨再造丸的药效机制。 方法 将骨髓间充质干细胞(BMSCs)分为空白对照组、地塞米松+LPS模型对照组、模型对照组+Dynarrestin组、模型对照组+生骨再造丸含药血清组。对上述细胞进行相应处理后,收集各组细胞,CCK8检测各组BMSCs细胞活力;流式细胞术检测各组BMSCs凋亡率;Western blot检测各组Dyneie、NLRP3、Caspase-1、GSDMD蛋白的表达;ELISA检测各组细胞中IL-1β和IL-18含量。 结果 与空白对照组比较,地塞米松+LPS模型对照组细胞活力下降、凋亡水平上升,Dyneie、NLRP3、Caspase-1、GSDMD蛋白的表达上升(P0.0001),IL-1β和IL-18含量明显增加(PPP 结论 生骨再造丸通过靶向Dynein的激活位点,抑制NLRP3蛋白的微管依赖性转运,最终抑制NLRP3炎性小体组装,从而有效降低BMSCs焦亡水平。
