摘要: 目的 检测四种小型猪在内源性逆转录病毒基因(PERV)拷贝数上的差异,试图找出不舍或含有较低拷贝数的个体或品种。方法 采用半定量PCR方法检测了我国四种小型猪内源性逆转录病毒基因的拷贝数。结果 贵州小型猪、五指山猪、西藏小型猪、巴马小型猪的PERV的拷贝数分别是34.12±16.96,29.38±13.83,28.71±14.11,27.12±14.43(F=0.614,P=0.609),EnvA的拷贝数分别是9.78±5.48,10.06±5.34,10.23±5.71,10.51±6.23(F=0.044,P=0.988),EnvB的拷贝数分别是24.14±11.26,20.72±8.36,18.35±8.50,17.60±8.65(F=1.512,P=0.221)。尚不能认为四个猪种间PERV、EnvA、EnvB的拷贝数之间的差异具有统计学意义。结论 四种常用的小型猪内源病毒负载量较低,表明其用于异种器官移植研究的可行性。

Abstract: Objective Estimate difference of PERV copy-number of mini-pigs in China, and to find out breeds or individuals with no or low vims copy-number. Methods Semi-quantitative PCR method was used in this research to estimate PERV copy-number of four mini-pigs in China. Results The copy-number of PERV, EnvA, EnvB gnes in Guizhou mini-pig, Wuzhishan mini-pig, Tibet mini-pig, Bama mim-pig were 34.12±16.96, 29.38±13.83, 28.71±14.11,27.12±14.43(F=0.614, P = 0.609), 9.78 士 5.48,10.06 土 5.34,10.23 土 5.71,10.51 土 6.23(F=0.044,P = 0.988),24.14 土 11.26, 20.72 士 8.36,18.35 土 8.50,17.60 土 8.65(F=1.512,P</i>=0.221) respectively. According to these results, no significant differences were observed in the copy-number of PERV, EnvA, EnvB among four different mini-pig breeds. Conclusion The four stocks of commonly used mini-pigs have relatively low endogenous vims copy-number, and it may be used for xenotransplantation research.
