摘要: 目的克隆大鼠心脏TNNT2基因,研究其表达情况。方法以成年SD大鼠心脏为实验材料,提取其总RNA并反转录;根据Genebank中提供的大鼠TNNT2基因cDNA序列,利用PCR方法扩增此序列,并进行表达研究。结果克隆了大鼠心脏TNNT2基因cDNA全长,反转录后克隆出TNNT2cDNA全长并与Genebank中提供的序列对比发现了新的cNDA序列,递交至Genebank数据库,登陆号为:EU295527。组织表达谱研究表明TNNT2基因在大鼠心脏、肾、肝、脾、肺、肌肉中均有表达,以心脏中表达最高(P<0.05)。结论首次克隆了大鼠TNNT2cDNA,Genebank登陆号:EU295527。TNNT2基因在多种组织中有表达,在心脏中表达最高。

Abstract: Objective To Clone the gene of TNNT2 and analyze its expression. Methods Total RNA was extracted from the heart of adult SD rat and first strand cDNA was obtained by reverse transcription. Primers was designed according to the offered sequence in Genebank. TNNT2 cDNA was cloned by PCR and confirmed by sequencing,RT-PCR was applied to examine the expression pattern of TNNT2 in rat tissues. Results The TNNT2 cDNA sequence was cloned and submitted it to Genebank (Genebank acc.No.EU295527), the TNNT2 was expressed in many tissues and had the highest expression level in heart. Conclusions Rat TNNT2 cDNA sequence was first cloned(Genebank Acc.No.EU295527), TNNT2 was expressed in many tissue and had the highest expression level in heart.
