新基因C12ORF56在肺癌中的表达特征和功能研究OA北大核心CSTPCD
Expression pattern and function of novel gene C12ORF56 in lung cancer
目的 C12ORF56(chromosome 12 open reading frame 56)是一个位于人染色体12长臂14.2区、且目前功能未知的新基因,在多种正常组织及包括肺癌在内的多种肿瘤中均有表达,但是C12ORF56在肺癌中的表达特征及功能尚不明确.在本研究中我们对C12ORF56在肺癌组织及细胞系中的表达及亚细胞定位特征、细胞生理功进行了探讨.方法 在ONCOMINE数据库中比较了正常组织和肺癌组织的C12ORF56 mRNA 的转录水平;并使用 LinkedOmics、Metas-cape、String 和GSEA等工具对C12ORF56及其关联的分子调控网络在肺癌病理过程中的潜在细胞生物学功能进行了预测;通过EdU和CCK-8法评估了特异性siRNA靶向敲降C12ORF56 mRNA对肺癌细胞系NCI-H1073增殖的影响;应用RT-qPCR检测肺癌细胞周期各阶段中C12ORF56的转录水平;采用Jaspar在线工具预测,并通过双荧光素酶报告基因系统明确了影响肺癌细胞系中C12ORF56基因转录的启动子核心区域.结果 相对于正常组织,C12ORF56转录本在肺癌组织、特别是在鳞状细胞肺癌中表达明显上调;靶向敲降C12ORF56明显抑制了肺癌细胞NCI-H1703的增殖.结论 C12ORF56转录水平在肺癌组织、特别是鳞状细胞肺癌组织中明显上调;上调的C12ORF56通过促进肿瘤细胞的增殖参与肺癌的发生和发展进程.
Aim To disclose the subcellular localiza-tion,expression pattern,cellular physiological function and possible molecular mechanism of C12ORF56,a novel gene located at q14.2 of chromosome 12,in the pathogenesis of lung cancer.Methods ONCOMINE database was applied to investigate the mRNA level dif-fering of C12ORF56 between normal and lung cancer tissues.Analysis based on LinkedOmics,Metascape,String and GSEA database or tools provided indication of potential cellular physiological functions of C12ORF56 in the developing of lung cancer.C12ORF56 was knocked down via siRNA and the pro-liferation of NCI-H1073 cells were observed by EdU and CCK-8 assay.RT-qPCR was used to detect the ex-pression level of C12ORF56 of lung cancer cells on dif-ferent cycle phases.The core sequence regions of pro-moter affecting the transcription of C12ORF56 gene were analyzed by Jaspar online-tools and verified by dual-luciferase assay.Results C12ORF56 was highly expressed in lung cancer cells,especially in squamous cell lung cancer.C12ORF56 correlated with cell cy-cle,cancer immune,DNA replication.Knockdown of C12ORF56 reduced NCI-H1703 cell proliferation.Conclusion The up-regulation of C12ORF56 is in-volved in the development of lung cancer by enhancing lung cancer cell proliferation.
