摘要:

背景:人源核不均一核糖核蛋白E1功能广泛,可参与神经系统骨架蛋白的表达。
目的:为深入研究其在神经细胞中的作用,构建其真核表达载体,观察其在神经细胞中的表达。
方法:利用真核表达载体pcDNATM4/His C,通过亚克隆构建核不均一核糖核蛋白E1-pcDNATM4/His C重组质粒,经酶切、测序鉴定,通过转染神经细胞SH-SY5Y,采用western-blot,RT-PCR鉴定核不均一核糖核蛋白E1重组质粒的表达,并观察转染细胞的生长现象。
结果与结论:成功构建了核不均一核糖核蛋白E1的真核表达载体,mRNA和蛋白水平上均证实了该质粒可在神经细胞SH-SY5Y中正确表达。SH-SY5Y细胞在转染核不均一核糖核蛋白E1后表现为加速生长。提示该蛋白对神经细胞的生长发育具有重要的作用。该载体为进一步研究核不均一核糖核蛋白E1在神经系统中的功能提供了前提条件。

Abstract:

BACKGROUND: The functions of homo heterogeneous ribonucleoprotein E1 are very wide. It can participate in the expression of skeleton proteins in the nervous system.
OBJECTIVE: To construct the recombinant plasmid of homo heterogeneous ribonucleoprotein E1 and observe its expression in nerve cells for further studying the functions of it in neurocytes.
METHODS: Using pcDNATM4/His C, the homo heterogeneous ribonucleoprotein E1 was subcloned into recombinant plasmid E1-pcDNATM4/His C, followed by enzyming and sequencing. After SH-SY5Y cells were transfected with the recombinant plasmid, western blot analysis and real time RT-PCR were used to detect the expression of homo heterogeneous ribonucleoprotein E1 in SH-SY5Y cells. And the growth of SH-SY5Y cells was observed.
RESULTS AND CONCLUSION: We successfully constructed the eukaryotic expressed vector of homo heterogeneous ribonucleoprotein E1. The recombinant plasmids were verified to express in SH-SY5Y cells correctly at mRNA and protein levels. And SH-SY5Y cells generated quickly after homo heterogeneous ribonucleoprotein E1 was over-expressed. The homo heterogeneous ribonucleoprotein E1 is an important protein in neural development. And this vector offers the premise for further studying its function in nervous system.
