Sequence Variations of MicroRNAs in Human Cancer: Alterations in Predicted Secondary Structure Do Not Affect Processing
Abstract
Expression levels of microRNAs (miRNAs) are globally reduced in cancer compared with matched normal tissues, and miRNA function has recently been implicated in tumorigenesis. To test whether epigenetic silencing contributes to miRNA suppression in tumors, lung cancer cells were treated with inhibitors of DNA methylation or histone deacetylation. No significant alteration in miRNA expression was detected using microarray profiling. To search for tumor-associated mutations that could affect processing and expression of mature miRNAs, a panel of 91 cancer-derived cell lines was analyzed for sequence variations in 15 miRNAs implicated in tumorigenesis by virtue of their known target transcripts (let-7 family targeting oncogenic Ras) or their localization to sites of frequent chromosomal instability (miR-143, miR-145, miR-26a-1, and miR-21). No mutations were detected within any of the short mature miRNA sequences. In addition to previously reported polymorphisms, 1 sequence variant in a precursor miRNA and 15 variants in primary miRNA (pri-miRNA) transcripts were identified. Despite pri-miRNAs having dramatic changes in the predicted secondary folding structure flanking putative cleavage sites, processing and miRNA maturation were not affected in vivo. Thus, genetic variants in miRNA precursors are common in cancer cells but are unlikely to have physiologic significance. (Cancer Res 2006; 66(12): 6097-104)

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.
