目的寻找并验证与肿瘤相关的非编码RNA。方法采用RT-PCR和Northern blot分析非编码RNA在肿瘤组织及细胞系中的表达情况。结果RT-PCR在实体肿瘤和细胞系中鉴定了2个非编码RNA-NC28和NC119的表达,Northern blot检测发现NC28转录子长度大约为1800个核苷酸,NC119转录子长度大约为1200个核苷酸。结论这两种非编码RNA具有一定的肿瘤共享性,非编码RNA在肿瘤发生发展中可能发挥一定作用。
Objective To explore and identify the non-coding RNAs related to tumors. Methods We used RT-PCR and Northern blot to analyze non-coding RNAs in tumor tissues and cell lines. Results Two predicted non-coding RNAs were confirmed to be expressed in cancer tissues and cell lines by RT-PCR and DNA sequencing. We detected the expression of two non-coding RNA transcripts by Northern blot. The length of NC28 was about 1800 nt, and that of NC119 was about 1200nt. Conclusions NC28 and NC119 have a tumor-associated expression pattern. The non-coding RNAs may play a role in the development of tumors.
