摘要: 11β-羟类固醇脱氢酶1(11β-HSD1)可使无生物活性的皮质酮催化为有活性的皮质醇,本试验利用长白猪肝脏组织提取的RNA反转录出11β-HSD1基因的cDNA,通过反转录—聚合酶链式反应(RT-PCR)技术和DNA重组技术,将11β-HSD1基因构建到pcDNA3.1真核表达载体上,构建了11β-HSD1-pcDNA重组质粒。通过PCR扩增、酶切电泳和测序分析的方法对重组的质粒进行了鉴定,并将其转染了Hepa1-6细胞,通过RT-PCR检测了其过表达强度。试验结果表明,成功构建了猪11β-HSD1-pcDNA真核过表达载体,为转基因动物的研究奠定了基础。

Abstract: Glucocorticoids can be produced from inactive 11-keto forms through the enzyme 11β-hydroxysteroid dehydrogenase type 1. The cDNA of porcine 11β-HSD1 gene was amplified from the tissue of landrace pigs liver by RT-PCR and cloned into the eukaryotic expression vector pcDNA3.1. The recombinant was further identified by PCR amplification,enzyme digestion and DNA sequencing. The recombinant plasmid 11β-HSD1-pcDNA was transfected into the Hepa1-6 cell and its expression intensitye was detectable by RT-PCR. The results showed that the eukaryotic exprssion vector 11β-HSD1-pcDNA was successfully constructed which could provide a necessary basis for the research of transgenic pigs.

Key words: 11β-HSD1; eukaryotic expression; gene cloning; vector construction; transgenic
