中文摘要: 长链非编码RNA(long noncoding RNA,lncRNA)作为一类新的调控性非编码RNA,在非小细胞肺癌(non-small cell lung cancer, NSCLC)中的存在情况、功能机制和临床意义还不清楚。课题组前期通过生物信息学和数据分析,从全基因组表达谱数据中挖掘与NSCLC有关的长链非编码RNA的表达信息,筛选出770个具有显著表达差异的lncRNAs;其中,lncRNA-00673作为差异表达最为显著的上调基因,引起我们的关注。进一步,我们通过定量RT-PCR在独立样本中证实lncRNA-00673在NCSLC组织中表达显著上调,并且初步功能实验发现lncRNA-00673具有促进肺癌细胞的迁移和侵袭作用。本项目将基于前期基础上,进一步阐明lncRNA-00673在NSCLC发生发展过程中的功能和作用机制,并探讨其临床意义,为NSCLC的发病机制提供新的思路。

英文摘要: Dysregulation of long noncoding RNAs (lncRNAs) has been considered as a primary feature of several human cancers. However, the genome-wide expression and functional significance of lncRNAs in non-small cell lung carcinomas (NSCLC) remains unclear. Through microarray gene expression analysis, we identified a list of 770 candidate lncRNAs significantly dysregulated in NSCLC tumors compared with normal lung tissues. Among which, lncRNA-00673 was particularly interesting as one of the most up-regulated lncRNAs in NSCLC tumors. The overexpression of lncRNA-00673 was further confirmed using quantitative real-time PCR technique. The primary results of functional analysis showed that lncRNA-00673 may play a role in promoting the migration and invasion of NSCLC cells. These observations indicated that lncRNA-00673 may represent a potential biomarker for diagnosis, prognosis and treatment of NSCLC. Future studies will focus on the functional elucidation of lncRNA-00673 in NSCLC pathogenesis, and verifications of its utility with large clinical samples.
