摘要

目的:结缔组织生长因子（Connective tissue growth factor

CTGF）含有4个不同功能结构域

构建表达带有3×Flag标签的全长基因及5个缺失突变体的重组腺病毒

以研究CTGF各结构域的功能和作用机制。方法:通过聚合酶链反应（Polymerasechain reaction

PCR）等克隆方法制备目标质粒DNA

然后通过腺病毒穿梭载体与骨架载体的重组、包装构建全长CTGF和缺失突变体重组腺病毒。用anti-Flag抗体作为一抗做Western blot检测目的基因表达情况。结果:通过腺病毒基因组DNA PCR确认有CTGF全长和缺失突变体的存在;Western blot法验证了CTGF全长和缺失突变体的表达。结论:成功构建了6个表达CTGF全长和缺失突变体的重组腺病毒

为进一步研究CTGF的结构域功能奠定了基础。

Abstract

Objective:Connective tissue growth factor(CTGF)

which contains four modules

plays an important role in both cell proliferation and differentiation.This study is to elucidate the distinctive function of each module

and to establish recombinant adenoviruses that express full length and deletion mutants of CTGF gene.Methods:Six plasmids containing full-length CTGF

CTGFCD1(no module Ⅳ)

CTGFCD2(no module Ⅲand Ⅳ)

CTGFID1(no module Ⅱ)

CTGFID2(no module Ⅲ)

CTGFID3(no module Ⅱ or Ⅲ) were constructed with Polymerase chain reaction(PCR) and gene cloning techniques.The corresponding adenoviruses were generated by recombination and packaging

and evaluated by PCR and Western blot.Results:The presence of full-length CTGF or CTGF deletion mutants in these recombinant adenoviruses was confirmed by DNA sequencing and PCR

and the expression of these CTGF constructs was confirmed by Western blot with anti-Flag antibody to the fusion 3×Flag tag at the C-terminus of these constructs.Conclusion:Six recombinant adenoviruses that express full-length CTGF and deletion mutants have been successfully established

which could facilitate the dissection of CTGF protein function.
