miRNA editing--we should have inosine this coming.

چکیده
In a recent issue of Science, Nishikura and colleagues provide the first evidence that editing of a microRNA (miRNA) precursor by ADARs can modulate the target specificity of the mature miRNA (Kawahara et al., 2007).

Systematic characterization of A-to-I RNA editing hotspots in microRNAs across human cancers.
RNA editing, a widespread post-transcriptional mechanism, has emerged as a new player in cancer biology. Recent studies have reported key roles for individual miRNA editing events, but a comprehensive picture of miRNA editing in human cancers remains largely unexplored. Here, we systematically characterized the miRNA editing profiles of 8595 samples across 20 cancer types from miRNA sequencing ...
متن کاملFrequency and fate of microRNA editing in human brain
Primary transcripts of certain microRNA (miRNA) genes (pri-miRNAs) are subject to RNA editing that converts adenosine to inosine (A-->I RNA editing). However, the frequency of the pri-miRNA editing and the fate of edited pri-miRNAs remain largely to be determined. Examination of already known pri-miRNA editing sites indicated that adenosine residues of the UAG triplet sequence might be edited m...
متن کاملRedirection of silencing targets by adenosine-to-inosine editing of miRNAs.
Primary transcripts of certain microRNA (miRNA) genes are subject to RNA editing that converts adenosine to inosine. However, the importance of miRNA editing remains largely undetermined. Here we report that tissue-specific adenosine-to-inosine editing of miR-376 cluster transcripts leads to predominant expression of edited miR-376 isoform RNAs. One highly edited site is positioned in the middl...
متن کاملHypothesis: RNA editing of microRNA target sites in humans?
Adenosine (A) to inosine (I) RNA editing occurs widely in the human transcriptome, and a large proportion of editing sites are within untranslated regions (UTRs). MicroRNAs (miRNAs), an abundant class of regulatory genes, specify the expression of a large number of target genes by pairing to their 3' UTRs. To study the interplay between these two post-transcriptional events, we developed a comp...
متن کاملReprogramming of microRNAs by adenosine-to-inosine editing and the selective elimination of edited microRNA precursors in mouse oocytes and preimplantation embryos
Adenosine deaminases-acting-on-RNA (ADAR) proteins induce adenosine-to-inosine editing in double-stranded RNA molecules. This editing generates RNA diversity at the post-transcriptional level, and it has been implicated in the control of cell differentiation and development. The editing of microRNA (miRNA) precursors, along with Tudor-SN (Snd1) activity, could lead to the elimination of selecte...
