摘要:
利用FuGENE6将线性化的pLiv-11-Neor/Kanr-hNPC1L1转染至小型猪胎儿成纤维细胞,G418筛选和PCR鉴定结果表明,成功获得了肝特异性表达人尼曼-匹克C1型类似蛋白1(Human Niemann-Pick C1 Like 1, hNPC1L1)转基因小型猪胎儿成纤维细胞。利用体细胞核移植技术将转hNPC1L1基因小型猪胎儿成纤维细胞作为核供体细胞,获得了肝特异性表达hNPC1L1转基因巴马小型猪,并对转基因巴马小型猪进行了基因组水平、转录水平和表达水平检测,同时对目的基因进行了免疫组化定位分析。结果显示,目的基因特异性地表达于肝组织,并且定位于肝小叶间胆管膜上,表明已成功获得了转hNPC1L1基因巴马小型猪,从而为研究尼曼-匹克C1型类似蛋白1 (Niemann-Pick C1 Like 1, NPC1L1)在肝中作用的分子机制提供了很好的模型动物。
Abstract:
In this study, the minipig fetal fibroblast cells with human Niemann-Pick C1-like NPC1L1 specially expressed in liver were obtained through transfecting linearized vector pLiv-11-Neor/Kanr-hNPC1L1 into minipig fetal fibroblast cell by FuGENE 6. The positive clones were selected with G418 and identified by PCR. The transgenic Bama miniature pigs with hNPC1L1 specifically expressed in the livers were generated by using somatic cell nuclear transfer technique with the minipig fetal fibroblast cells as nuclear donor cells. The transgenic Bama miniature pigs were detected on the genomic level, transcription level and expression level. Meanwhile, the target gene was analyzed by immunohistochemistry. The results showed that the target gene was specifically expressed in the liver tissue and localized on the hepatic interlobular bile duct membrane. The successful generation of hNPC1L1 transgenic Bama miniature pigs will provide a model animal for studying the molecular mechanism of NPC1L1 in liver.
