ARTICLE ABSTRACT
Increasing evidence has suggested a role for adenosine-to-inosine RNA editing in carcinogenesis. However, the clinical utility of RNA editing remains limited because functions of the vast majority of editing events remain largely unexplored. To help the cancer research community investigate functional consequences of individual editing events, we have developed a user-friendly bioinformatic resource, The Cancer Editome Atlas (TCEA; http://tcea.tmu.edu.tw). TCEA characterizes >192 million editing events at >4.6 million editing sites from approximately 11,000 samples across 33 cancer types in The Cancer Genome Atlas. Clinical information, miRNA expression, and alteration in miRNA targeting modulated through RNA editing are also integrated into TCEA. TCEA supports several modules to search, analyze, and visualize the cancer editome, providing a solid basis for investigating the oncogenic mechanisms of RNA editing and expediting the identification of therapeutic targets in cancer.
This user-friendly bioinformatic resource reduces the barrier to analyzing the huge and complex cancer RNA editome that cancer researchers face and facilitates the identification of novel therapeutic targets in cancer.
