Abstract

Short RNA expression was analyzed from Dicer -positive and Dicer -knockout mouse embroyonic stem (ES) cells, using high-throughput pyrosequencing. A correlation of miRNA quantification with sequencing frequency estimates that there are 110,000 miRNAs per ES cell, the majority of which can be accounted for by six distinct miRNA loci. Four of these miRNA loci or their human homologues have demonstrated roles in cell cycle regulation or oncogenesis, suggesting that a major function of the miRNA pathway in ES cells may be to shape their distinct cell cycle. Forty-six previously uncharacterized miRNAs were identified, most of which are expressed at low levels and are less conserved than the set of known miRNAs. Low-abundance short RNAs matching all classes of repetitive elements were present in cells lacking Dicer , although the production of some SINE- and simple repeat-associated short RNAs appeared to be Dicer-dependent. These and other Dicer-dependent sequences resembled miRNAs. At a depth of sequencing that approaches the total number of 5′ phosphorylated short RNAs per cell, miRNAs appeared to be Dicer's only substrate. The results presented suggest a model in which repeat-associated miRNAs serve as host defenses against repetitive elements, a function canonically ascribed to other classes of short RNA.

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.
