Abstract

Most mammalian genes often feature alternative polyadenylation (APA) sites and hence diverse 3'UTR lengths. Proliferating cells were reported to favor APA sites that result in shorter 3'UTRs. One consequence of such shortening is escape of mRNAs from targeting by microRNAs (miRNAs) whose binding sites are eliminated. Such a mechanism might provide proliferation-related genes with an expression gain during normal or cancerous proliferation. Notably, miRNA sites tend to be more active when located near both ends of the 3'UTR compared to those located more centrally. Accordingly, miRNA sites located near the center of the full 3'UTR might become more active upon 3'UTR shortening. To address this conjecture we performed 3' sequencing to determine the 3' ends of all human UTRs in several cell lines. Remarkably, we found that conserved miRNA binding sites are preferentially enriched immediately upstream to APA sites, and this enrichment is more prominent in pro-differentiation/anti-proliferative genes. Binding sites of the miR17-92 cluster, upregulated in rapidly proliferating cells, are particularly enriched just upstream to APA sites, presumably conferring stronger inhibitory activity upon shortening. Thus 3'UTR shortening appears not only to enable escape from inhibition of growth promoting genes but also to potentiate repression of anti-proliferative genes.

  • Many miRNAs have a strong tissue-specific expression pattern and the 3' UTR of target gene plays a critical role in determining miRNA-target interaction.

    “Many miRNAs have a strong tissue-specific expression pattern and 3’ UTR of target gene plays a critical role in determining the miRNA-target interaction [136, 137].”

    From MicroRNAs in brain cholesterol metabolism and their implications for Alzheimer's disease (2016) · cites this paper as [137]

    The Introduction (page not provided) says that the position of a binding site along a target’s 3′ UTR can influence whether miRNA repression occurs, supporting the 3′ UTR part of the claim. The passages on miRNA expression concern changes between cellular states, not a strong tissue-specific expression pattern for many miRNAs; searches for tissue-specific miRNA expression did not establish that part.

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.
