摘要: 目的 为建立阿尔茨海默病APPswe/PS1dE9转基因小鼠生物学特性标准化资料提供实验依据。方法 APPswe/PS1dE9转基因小鼠杂合子交配繁殖,建立基因型鉴定方法, 选择160窝次的1158只小鼠分别统计4胎内不同胎次、不同基因型的繁殖性能及生长发育指标。结果 ①APP/PS1片段大小为600 bp; ②第2胎和第3胎的仔鼠数量及阳性数量均大于第1胎(P<0.05), 阳性率则无明显差异(P>0.05); ③第1、2胎之间的胎间隔天数较短(P<0.05),第2、3胎的窝产仔数、离乳仔数及离乳率均高于其它两胎(P<0.05); ④第3胎和第4胎的初生窝重、泌乳力和离乳个体重较为稳定; ⑤雌雄APP/PS1小鼠的最高体重分别为24.45±0.92 g和30.21±2.53 g; ⑥该转基因小鼠的基因型不影响其体重(P>0.05)。结论 建立了APP/PS1小鼠的基础生物学特性资料; 为科学研究提供基础数据

Abstract: Objective To afford experimental basis for establishing the standard biological properties' datum of APPswe/PS1dE9 transgenic mice model on Alzheimer's disease. Methods The heterozygote of the APP/PS1 transgenic mice were used to breed, and the identify method of genotype was established. The reproductive performance and growth of different litters and genotype were analysed within four litters of 1158 mice in 160 litters. Results ① The section of APP/PS1 was 600 bp. ② The quantity of the newborn mice and transgenic positive in litter 2 and 3-were more than litter 1(P<0.05), but the positive rate had no significant difference(P>0.05). ③ The birth interval between parity 1 and 2 was shorter than other's (P<0.05). Litter size, number of mice weaned and survival rate after weaning of the parity 2 and 3 were higher than other two (P<0.05). ④ The litter weight at birth, lactescence, body weight after weaning of parity 3 and 4 were stable. ⑤ The highest weight of female and male APP/PS1 transgenic mice are 24.45±0.92 g and 30.21±2.53 g separately. ⑥ This transgenic mouse genotype did not affect its weight. Conclusions The basic biological characteristics data of APP/PS1 transgenic mouse are established, and provide the exact data for scientific research.
