骨质疏松症是一种严重的公共健康问题,淫羊藿苷(ICA)是中药淫羊藿的活性成分。本研究旨在探讨ICA作为骨质疏松症潜在疗法的作用和潜在机制。

从新生大鼠分离Calvaria成骨细胞并用ICA处理。分析细胞活力、细胞凋亡、碱性磷酸酶活性和钙沉积。使用生物信息学分析鉴定ICA处理后差异表达的蛋白质(DEP)。使用Western印迹分析验证DEP的表达。

结果显示ICA处理可促进成骨细胞活力、碱性磷酸酶活性、钙沉积和抑制成骨细胞凋亡。使用凝胶电泳和基质辅助激光解吸/电离飞行时间质谱对ICA处理的细胞的蛋白组进行分析。

结果共鉴定出56个DEPs,包括丝氨酸蛋白酶抑制剂家族F成员1(PEDF)、蛋白质二硫键异构酶家族A、成员3(PDIA3)、核蛋白、组蛋白转录共激活因子(NPAT)、c-Myc和热休克蛋白70(HSP70)。这些蛋白质与信号传导通路相关,包括Fas和p53。生物信息学和蛋白质印迹分析证实6种DEP的表达水平在ICA处理后上调。这些基因可能直接或间接参与ICA介导的成骨分化和成骨。

该研究结果证明ICA处理通过调节信号通路(包括Fas和p53)调节PEDF、PDIA3、NPAT和HSP70的表达来促进成骨。

Sci Rep:淫羊藿苷可有效修复骨缺损

通常,骨再生医学应用于骨质疏松症患者的骨缺损修复。同时,迫切需要开发安全、廉价的诱导骨形成的药物。研究发现淫羊藿苷(淫羊藿的主要活性成分)可促进体外成骨细胞的增殖。然而,淫羊藿苷能否修复骨质疏松引起的骨缺损目前尚不清楚。本实验中,研究人员首先建立了大鼠骨质疏松模型,然后评价淫羊藿苷处理的骨髓间充质干细胞(BMSCs)的成骨分化和血管生成分化的效果。此外,研究人员还构建了含淫羊藿苷的磷酸钙骨水泥支架

Front Pharmacol:淫羊藿苷有助于治疗骨感染

万古霉素是治疗由金黄色葡萄球菌引起的骨感染的有效抗生素,但万古霉素局部高浓度可能会延迟骨愈合。据报道,淫羊藿素可抑制破骨细胞生成,并促进成骨。本研究旨在探讨淫羊藿苷对体内抗感染治疗后骨修复的影响,并探讨淫羊藿苷对高剂量万古霉素抑制大鼠颅骨成骨细胞(ROBs)的作用。使用万古霉素-硫酸钙(VCS)和淫羊藿苷(10.86mg/kg/d)连续疗8周治疗金黄色葡萄球菌骨感染的兔子。使用微CT、形态学及血液
