最近我们利用新一代测序(next generation sequencing,NGS)技术对肝细胞癌(hepatocellular carcinoma,HCC)患者活检标本及正常对照肝组织样品进行高通量RNA测序(RNA-sequencing,RNA-Seq),在肝癌样品中染色体11q13.1区域检测到几个相邻的RNA-Seq信号峰,而在正常对照组织中没有检测到,且该染色体区域目前尚无已知基因登录,提示这几个RNA-Seq峰可能代表一个或多个未知的新基因.以此为线索,证实这几个RNA-Seq峰来自同一个新基因,并克隆了该基因全长序列,在克隆该基因全长序列时,发现该基因编码的RNA存在多种剪接形式,最长的转录本为3 562 bp.将该基因编码的12条代表性RNA转录本序列递交到美国国立生物技术信息中心(National Center for Biotechnology Information,NCBI)的GenBank数据库中,GenBank ID号分别为KC136297~KC136308.该基因编码的RNA没有发现明显的开放阅读框(open reading fragment,ORF),提示该基因可能编码长链非...
【英文摘要】
Recently, we sequenced the transcriptomes of a hepatocellular carcinoma biopsy and a normal liver tissue using the RNA-Sequencing(RNA-Seq) strategy based on the Next Generation Sequencing(NGS) technique, and identified several adjacent high RNA-Seq signal peaks on chromosome 11q13.1 in the hepatocellular carcinoma biopsy, while not in the normal control tissue. In this chromosome region, there is no characterized genes have been identified, implying that these RNA-Seq peaks may represent one or more novel g...
