Let-7 microRNA-mediated mRNA deadenylation and translational repression in a mammalian cell-free system
Open accessAbstract
MicroRNAs (miRNAs) are incorporated into miRNP complexes and regulate protein expression post-transcriptionally through binding to 3′-untranslated regions of target mRNAs. Here we describe a recapitulation of let-7 miRNA-mediated translational repression in a cell-free system, which was established with extracts prepared from HEK293F cells overexpressing miRNA pathway components. In this system, both the cap and poly(A) tail are required for the translational repression, and let-7 directs the deadenylation of target mRNAs. Our work suggests that let-7 miRNPs containing Argonaute and GW182 impair the synergistic enhancement of translation by the 5′-cap and 3′-poly(A) tail, resulting in translational repression.

“In contrast to the disparate results obtained from studies in cells, in vitro experiments in cell-free translation extracts prepared from mammalian or Drosophila embryos all indicated that miRNAs suppress cap-dependent but not IRES-mediated translation (Mathonnet et al., 2007; Thermann and Hentze, 2007; Wakiyama et al…”

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.
