背景合作项目如癌症基因组图谱(TCGA)已经产生了关于癌症的各种组学和临床数据。已经开发了许多计算工具,以便于使用TCGA数据研究肿瘤的分子特征。选择性剪接的基因产生剪接变异体,并积累的证据已经揭示了其在癌症相关过程中的重要作用,这意味着迫切需要发现肿瘤特异性异构体,并揭示其在tumorigenes.ResultWe开发的TSVdb,基于网络的工具,探索选择性剪接的基础上TCGA样品与30个临床变量从33肿瘤。TSVdb有一个集成的和比例均匀的界面,用于可视化临床数据,基因表达,外显子/连接和剪接模式的使用。研究人员可以解释临床亚组之间或跨临床亚组的异构体表达差异,并估计异构体与患者预后之间的关系。TSVdb位于 http://www.tsvdb.com ,源代码可在 https://github.com/wenjie1991/TSVdb 结论TSVdb基因将对肿瘤学家起到启发作用,并将促进肿瘤研究在异构体水平上的进展。
BackgroundCollaborative projects such as The Cancer Genome Atlas (TCGA) have generated various -omics and clinical data on cancer. Many computational tools have been developed to facilitate the study of the molecular characterization of tumors using data from the TCGA. Alternative splicing of a gene produces splicing variants, and accumulating evidence has revealed its essential role in cancer-related processes, implying the urgent need to discover tumor-specific isoforms and uncover their potential functions in tumorigenesis.ResultWe developed TSVdb, a web-based tool, to explore alternative splicing based on TCGA samples with 30 clinical variables from 33 tumors. TSVdb has an integrated and well-proportioned interface for visualization of the clinical data, gene expression, usage of exons/junctions and splicing patterns. Researchers can interpret the isoform expression variations between or across clinical subgroups and estimate the relationships between isoforms and patient prognosis. TSVdb is available at http://www.tsvdb.com , and the source code is available at https://github.com/wenjie1991/TSVdb .ConclusionTSVdb will inspire oncologists and accelerate isoform-level advances in cancer research.
