| 摘 要： | 目的：为了以秀丽线虫为模式生物研究人源胞红蛋白（human cytoglobin,hCGB）的生理功能,构建hCGB的秀丽线虫表达载体,并通过显微注射的方法制备转基因线虫。方法：将通过RT-PCR获得的hCGB的cDNA序列亚克隆到pFX-unc-119表达载体中,通过显微注射的方法获取染色体外转基因线虫,采用紫外线（UV）照射的方法,筛选获得整合到染色体中的株系,并采取Western印迹和免疫组织化学法鉴定外源基因的表达。结果与结论：成功地构建了hCGB基因的表达载体并获得了3个hCGB的转基因线虫株系,同时获得了3个作为功能对照研究的增强型绿色荧光蛋白（EGFP）转基因线虫株系,为深入开展胞红蛋白的功能研究奠定了基础。 |

| Abstract: | Objective：To investigate the function of human cytoglobin （hCGB） and to construct the transgenic Cae- norhabditis elegans expressing hCGB. Methods：The coding region of hCGB obtained from human embryo brain mRNA with RT-PCR was subcloned into the pFX-unc-ll9 to prepare the vector pFX-unc-119：：hCGB. The vectors pFX-unc-I19：：hCGB and pFX-myo-2：：dsRed were microinjected into the gonad to generate extrachromosomal strains. Integral lines were obtained by ultraviolet （UV） irradiation. Expression of hCGB in transgenic strains was detected with Western blotting and immuno- histochemistry methods. Results and Conclusion：The hCGB expressing vector was successfully constructed. Three hCGB and three EGFP transgenic strains were obtained, which will facilitate further function studies of CGB. |
