| 1 | The Integrative Studies on the Functional A-to-I RNA Editing Events in Human Cancers显示文摘Adenosine-to-inosine(A-to-I)RNA editing,constituting nearly 90%of all RNA editing events in humans,has been reported to contribute to the tumorigenesis in diverse cancers.However,the comprehensive map for functional A-to-I RNA editing events in cancers is still insufficient.To fill this gap,we systematically and intensively analyzed multiple tumorigenic mechanisms of A-to-I RNA editing events in samples across 33 cancer types from The Cancer Genome Atlas.For individual candidate among1,500,000 quantified RNA editing events,we performed diverse types of downstream functional annotations.Finally,we identified 24,236 potentially functional A-to-I RNA editing events,including the cases in APOL1,IGFBP3,GRIA2,BLCAP,and miR-589-3p.These events might play crucial roles in the scenarios of tumorigenesis,due to their tumor-related editing frequencies or probable effects on altered expression profiles,protein functions,splicing patterns,and microRNA regulations of tumor genes.Our functional A-to-I RNA editing events(https://ccsm.uth.edu/CAeditome/)will help better understand the cancer pathology from the A-to-I RNA editing aspect. | Sijia Wu Zhiwei Fan Pora Kim Liyu Huang Xiaobo Zhou | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
