目的:构建satb2的真核过表达载体,观察转入重组载体后C3H10T1/2细胞中satb2的表达情况.方法:根据satb2基因CDS区设计引物,以PCR的方法获得目的基因,将satb2片段双酶切后插入到pGV141载体中进行重组质粒的构建,用PCR和基因测序进行鉴定,将构建成功的重组质粒转染入C3H10T1/2细胞,并通过目的蛋白的检测观察satb2在骨髓间充质干细胞中的表达情况.结果:重组过表达载体GV141-satb2构建成功;与未转染质粒C3H10T1/2细胞相比,转染pGV141-satb2质粒的C3H10T1/2细胞中satb2蛋白表达显著增高,差异有统计学意义(P＜0.05).结论:satb2真核过表达载体构建成功,体外转染实验证实可显著提高骨髓间充质C3H10T1/2细胞中satb2蛋白的表达.
Construction of Satb2 Eukaryotic Expression Vector and Its Expression in Bone Marrow Mesenchyme Stem Cells
Objective:To construct the eukaryotic expression vector of satb2,and to investigate the expression in bone marrow mesenchyme stem cells (BMSCs) after transfection.Methods:PCR method was employed to obtain the CDS region of satb2.And then the fragment of satb2 was inserted into GV141 vector following by XhoI/ EcoRI digestion.The recombinant vector was verified by PCR and DNA sequencing methods.The satb2 expression was detected by western blot after the recombinant vector transfected into BMSCs.Results:pGV141-satb2 was confirmed to be successfully constructed by PCR and DNA sequencing method.Compared with non-transfected group,the expression of satb2 protein was significantly higher in pGV141-satb2 transfection group.Conclusion:The eukaryotic expression vector of satb2 is successfully constructed and can enhance the satb2 expression in BMSCs after transfection.
