The Genomic Landscape and Clinical Relevance of A-to-I RNA Editing in Human Cancers
Open accessAbstract
Adenosine-to-inosine (A-to-I) RNA editing is a widespread post-transcriptional mechanism, but its genomic landscape and clinical relevance in cancer have not been investigated systematically. We characterized the global A-to-I RNA editing profiles of 6,236 patient samples of 17 cancer types from The Cancer Genome Atlas and revealed a striking diversity of altered RNA-editing patterns in tumors relative to normal tissues. We identified an appreciable number of clinically relevant editing events, many of which are in noncoding regions. We experimentally demonstrated the effects of several cross-tumor nonsynonymous RNA editing events on cell viability and provide the evidence that RNA editing could selectively affect drug sensitivity. These results highlight RNA editing as an exciting theme for investigating cancer mechanisms, biomarkers, and treatments.

To ensure sufficient statistical power, editing sites were kept only if they had at least three edited reads in at least 3 samples and no less than 30 samples with coverage as 10 in a brain region.
“To ensure sufficient statistical power, we only kept editing sites with at least three edited reads in at least 3 samples and no less than 30 samples with coverage as 10 in a brain region (18).”
From Comprehensive characterization of the transcriptional landscape in Alzheimer’s disease (AD) brains (2025) · cites this paper as [18]
The Experimental Procedures section gives both thresholds: at least three edited reads in at least three samples, followed by at least 30 samples with coverage ≥10. But it applies them per tissue or tumor type in a cancer study, not specifically in a brain region. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
