title: Behavior of calf Sertoli cells and fibroblast cells transfected with the human HNP-1 gene.
abstract: Human neutrophil peptide-1 (HNP-1) is an important defense molecule in neutrophils and Sertoli cells and plays an important role in the blood-testis barrier. In this study, we investigated the behavior of Sertoli cells transfected with the HNP-1 gene and compared the ability of Sertoli cells and fibroblast cells to resist transfection. Total RNA was isolated from human blood. The DNA coding sequence of HNP-1 was amplified by reverse transcription-polymerase chain reaction (RT-PCR) and the eukaryotic expression vector pEGFP-N3-HNP-1 was identified by PCR, endonuclease digestion, and sequencing. Bovine Sertoli cells and fibroblast cells were transfected with pEGFP-N3-HNP-1 using Liposome reagent. The transfection efficiency and the behavior of the transfected cells were evaluated at 24, 48 and 72 h as well as at other times after transfection. The plasmid pEGFP-N3-HNP-1 was successfully constructed. The cells achieved maximum transfection efficiency at 48 h. Two weeks after transfection, the cells began to stop dividing. The ability of Sertoli cells to resist transfection was higher compared to fibroblast cells. The ability of the 2 cell types to resist transfection was higher with plasmid pEGFP-N3-HNP-1 than with the plasmid pEGFP-N3. The injury to Sertoli cells caused by transfection with the HNP-1 gene was less pronounced than in fibroblast cells, which may be closely correlated with the physiological function of Sertoli cells.
