摘要: 为了克隆人多巴胺D2受体(D2R)基因以用于帕金森病的治疗,从人胎脑中提取总RNA,并逆转录成cDNA;设计一对引物用PCR方法扩增目的cDNA片段,并将其重组于pGEM-T载体中,酶切鉴定插入片段后,进行全序列测定。结果表明从人胎脑纹状体扩增出至少2种长度的cDNA片段,其中一个片段全长1445bp,序列与GenBank(NM000795)登录的序列完全相同;另一片段为1305bp,在第6外显子开始处有140bp的缺失,与已知的D2R3种转录体均不相同,可能为一种新的D2R转录体。

Abstract: In order to clone the human gene of dopamine D2 receptor for treatment of Parkinson disease, total cellular RNA was isolated from human fetal brain and reversely transcribed into cDNA, which was amplified by PCR with the specific primers. The PCR products were inserted into pGEM-T vector for sequencing after emzymatic analysis. The results showed that two fragments were obtained. One, 1 445 bp, was identical to that in the GenBank(NM000795)and the other, 1 305 bp with a deletion of 140 bp, was different from all the three transcripts of D2 receptors previously described and it may be a novel transcript.
