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.
