摘要: 为了检测牛GDF-9基因mRNA在怀孕期牛生殖系统的表达情况,为GDF-9基因在雌性动物繁殖上的研究提供一定的理论依据。本试验根据GenBank中报道的牛GDF-9基因序列设计引物,从牛卵巢、输卵管、子宫、肾脏中提取RNA,采用RT-PCR技术进行cDNA扩增,扩增产物与载体pGM-T连接,转化大肠杆菌DH5α,筛选阳性克隆,测序。结果表明,已成功克隆的阳性重组子经测序鉴定其片段大小与预期大小完全一致,为26 bp。序列同源性分析比较表明,该cDNA及其推导的氨基酸序列与绵羊GDF-9cDNA和氨基酸序列同源性分别为97%和9%。以β-actin为内参照物,采用RT-PCR技术进行半定量分析,通过检测比较牛GDF-9基因在卵巢、输卵管、子宫、肾脏组织中mRNA的表达情况。结果表明,牛GDF-9基因在卵巢中表达量最高,在输卵管、子宫、肾脏中均有表达,但表达量不高。

Abstract: In order to offer more theory of female reproductive performance, the expression of GDF-9 gene mRNA at the period of pregnaney bovine was detected. First, total RNA was isolated from the bovine ovaries, and the primers were designed according to the GenBank, cDNA was amplified with RT-PCR, then cloned into Excoli DH5α by using pGM-T vector. Sequence analysis showed that the cloned 264 bp cDNA and the deduced amino acid sequence shared 97% and 94% homology respectively with ovine GDF-9 cDNA. According to βactin as inner Criteria, then the mRNA of GDF-9 gene were examined with RT-PCR. The result indicated that GDF-9 expressed in the bovine ovaries, oviduct, uterus and kidney, and the largest is in ovaries.
