Biotechnol Rep:植物来源的重组骨桥蛋白-Fc融合蛋白可增强骨生成

2019-03-10 不详 网络

骨桥蛋白(OPN)在骨再生过程中起重要作用。既往研究表明,重组人OPN能够在本塞姆氏烟草叶中表达并诱导成骨相关基因。然而,用Ni亲和层析从植物蛋白中纯化OPN仍然不够有效。 为了提高植物中蛋白质表达和纯化的质量,我们构建了基于Fc的OPN形式。 将完整的OPN蛋白与人IgG1 Fc结构域融合。在这里,我们显示植物产生的OPN-Fc增加蛋白质表达水平并促进重组蛋白质的纯化。 总之,该研究结果表明,植

骨桥蛋白(OPN)在骨再生过程中起重要作用。既往研究表明,重组人OPN能够在本塞姆氏烟草叶中表达并诱导成骨相关基因。然而,用Ni亲和层析从植物蛋白中纯化OPN仍然不够有效。

为了提高植物中蛋白质表达和纯化的质量,我们构建了基于Fc的OPN形式。 将完整的OPN蛋白与人IgG1 Fc结构域融合。在这里,我们显示植物产生的OPN-Fc增加蛋白质表达水平并促进重组蛋白质的纯化。

总之,该研究结果表明,植物产生的OPN-Fc可以刺激成骨相关基因如DMP1,OSX和Wnt3a的表达以及hPDL细胞中的钙沉积。 这些发现表明植物产生的OPN-Fc在将来具有潜在的组织工程应用。
