J Biomater Appl:原硅酸诱导的自噬在促进成骨细胞分化和矿化中的作用

2019-04-28 不详 网络

据报道,硅是一种元素,具有各种成骨生物学功能。然而,硅在骨生成中的精确细胞作用机制是难以捉摸的。在这里,我们检查自噬是否与原硅酸(独特的可溶性硅形式)刺激的前成骨细胞的成骨分化和矿化有关。通过自噬相关蛋白表达检测硅诱导的自噬。通过自噬抑制剂3-甲基腺嘌呤证实了原硅酸诱导的自噬与成骨过程之间的相关性。我们还通过骨质疏松症大鼠的骨矿物质密度,胶原染色,羟脯氨酸和免疫组织化学研究了其在体内的适用性。高于

据报道,硅是一种元素,具有各种成骨生物学功能。然而,硅在骨生成中的精确细胞作用机制是难以捉摸的。在这里,我们检查自噬是否与原硅酸(独特的可溶性硅形式)刺激的前成骨细胞的成骨分化和矿化有关。通过自噬相关蛋白表达检测硅诱导的自噬。通过自噬抑制剂3-甲基腺嘌呤证实了原硅酸诱导的自噬与成骨过程之间的相关性。我们还通过骨质疏松症大鼠的骨矿物质密度,胶原染色,羟脯氨酸和免疫组织化学研究了其在体内的适用性。

高于10μM的浓度增加了碱性磷酸酶活性,而高达50μM的浓度降低了碱性磷酸酶活性。浓度高达20μM的原硅酸增加了成骨指标,自噬相关因子SQSTM1 / p62的表达,以及微管相关蛋白1中微管相关蛋白1轻链3-II(LC3-II)的转化根据Western印迹分析,轻链3-I(LC3-I)。在蛋白质印迹分析中,3-甲基腺嘌呤的应用降低了Runt相关转录因子2(RUNX-2),骨形态发生蛋白-2和胶原蛋白I的表达。低剂量的原硅酸补充大鼠(OVX-1,2)表现出骨胶原纤维表达率,骨矿物质密度,股骨羟脯氨酸含量和骨形态发生蛋白-2等参数的改善;而高剂量组(OVX-3,4)没有表现出更好的结果。

总之,本研究表明,原硅酸通过诱导自噬来刺激培养的前成骨细胞的成骨分化和矿化。此外,它还可以增强骨质疏松症大鼠的骨矿物质密度。
