摘要(Abstract):
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p GV141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p GV141-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。
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 Xho I/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: p GV141-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 p GV141-satb2 transfection group. Conclusion: The eukaryotic expression vector of satb2 is successfully constructed and can enhance the satb2 expression in BMSCs after transfection.
