Abstract

Antisense RNAs are non-coding RNAs that can regulate their corresponding sense RNAs and are generally produced from specific promoters. We uncover here a family of antisense RNAs, named START RNAs, produced during cellular senescence by transcriptional read-through at convergent protein-coding genes. Importantly, START RNAs repress the expression of their corresponding sense RNAs. In proliferative cells, we found that the Pol II elongation rate is limited downstream of TTS at START loci, allowing transcription termination to occur before Pol II reaches the convergent genes, thus preventing antisense RNA production and interference with the expression of the convergent genes. START RNAs are repressed by H2A.Z histone variant, whose local occupancy decreases in senescence. Our results thus uncover a mechanism of gene expression regulation relying on read-through antisense transcript production at convergent genes, underlining the functional importance of chromatin regulation in the control of RNA pol II elongation rate at intergenic regions.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Transcription speed increases downstream of two genes in response to activation of an oncogene and correlates with an increase in transcriptional read-through downstream of these genes.

    “Interestingly, we recently showed that transcription speed increases downstream of two genes in response to activation of an oncogene and that this increase correlates with an increase in transcriptional read‐though downstream of these genes (Muniz et al, 2017).”
  • The increase in RNA Pol II velocity downstream of genes is accompanied by an increase in transcriptional read-through which interferes with and thus decreases the expression of downstream convergent protein-coding genes.

    “Moreover, we have shown that the increase in RNA Pol II velocity downstream of genes is accompanied by an increase in transcriptional read‐through which interferes with and thus decreases the expression of downstream convergent protein‐coding genes (Muniz et al, 2017).”
  • Transcription speed increases downstream of some protein-coding genes in response to an oncogenic signal.

    “Third, transcription speed increases downstream of some protein‐coding genes in response to an oncogenic signal (Muniz et al, 2017).”
  • Convergent genes, antisense to the transcriptional read-through induced in response to oncogene-induced senescence, are enriched in pro-proliferative genes.

    “Indeed, we have shown that those convergent genes, antisense to the transcriptional read‐through induced in response to oncogene‐induced senescence, are enriched in pro‐proliferative genes (Muniz et al, 2017).”
  • Local modification of chromatin and RNA Pol II speed was exemplified in cells undergoing oncogene-induced senescence downstream of two genes, leading to extended transcriptional read-through.

    “We recently exemplified such a local modification of chromatin and RNA Pol II speed in cells undergoing oncogene‐induced senescence downstream of two genes, leading to extended transcriptional read‐through (Muniz et al, 2017).”

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.
