猪胎儿成纤维细胞APOE基因的差异表达研究

[目的]研究APOE基因在不同代数的猪胎儿成纤维细胞中的差异表达。[方法]收集正常传代生长的第1、10、15、20、25、50代猪胎儿成纤维细胞,分别提取细胞总RNA。采用RT-PCR技术,检测不同代数猪胎儿成纤维细胞中APOE基因的表达。[结果]猪APOE基因在第1代猪胎儿成纤维细胞中表达水平最高,随着细胞代数的增加,表达量逐渐下降,到第50代表达量最低。[结论]APOE基因在不同代数的猪胎儿成纤维细胞中有选择性表达的趋势。

Differential Expression of APOEGene in Porcine Fetal Fibroblast Cells

[Objective]The aim was to study the differential expression ofAPOEgene in different generations of porcine fetal fibroblasts cells.[Method]The first,tenth,fifteenth,twentieth,twenty-fifth,fiftieth generations of porcine fetal fibroblast cells,which were normally grown and passed,were collected before total RNA was extracted respectively.The expression ofAPOEgene in different generations of porcine fetal fibro-blast cells was detected by RT-PCR technique.[Result]The expression level of porcine APOE mRNA in the first generation of porcine fetal fi-broblast cells was the highest,and then it gradually decreased with the increase of cell generations and was the lowest in the fiftieth generation.[Conclusion]The expression ofAPOEgene had the selective trend in different generations of porcine fetal fibroblast cells.
