Transgenerational Inheritance of an Acquired Small RNA-Based Antiviral Response in C. elegans

Open access
Rechavi, Oded, Minevich, Gregory, Hobert, Oliver·2011·Cell

Abstract

Induced expression of the Flock House virus in the soma of C. elegans results in the RNAi-dependent production of virus-derived, small-interfering RNAs (viRNAs), which in turn silence the viral genome. We show here that the viRNA-mediated viral silencing effect is transmitted in a non-Mendelian manner to many ensuing generations. We show that the viral silencing agents, viRNAs, are transgenerationally transmitted in a template-independent manner and work in trans to silence viral genomes present in animals that are deficient in producing their own viRNAs. These results provide evidence for the transgenerational inheritance of an acquired trait, induced by the exposure of animals to a specific, biologically relevant physiological challenge. The ability to inherit such extragenic information may provide adaptive benefits to an animal.

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

  • There is no evidence for the modification of the genetic core (DNA sequence) based on acquired characteristics.

    “The ‘inheritance of acquired characteristics’ has been suggested, although few mechanisms have been proposed, and there is no evidence for the modification of the genetic core (DNA sequence) based on acquired characteristics [157,159].”

    From Opinion: The Key Steps in the Origin of Life to the Formation of the Eukaryotic Cell (2024) · cites this paper as [159]

    The Introduction and Discussion (pages unavailable in our copy) support inheritance of an acquired antiviral response through small RNAs rather than a genetic template. They do not establish the broader claim that there is no evidence for acquired characteristics modifying DNA sequence. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Short RNAs produced by hunger and viral infection cause inheritance.

    “In contrast, short RNAs produced by hunger and viral infection cause inheritance [100,101,102].”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [100]

    The Discussion (page not available) says that small viRNAs induced by viral replication pass through the germline across generations, supporting the viral-infection part of the claim. Our copy does not report hunger-induced small RNAs or inheritance caused by hunger, so it does not support that part. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • C. elegans can translate a variety of environmental inputs, including viral infection, famine, and high temperatures, into modifications of some epigenetic elements.

    “With a different model, it has been demonstrated that C. elegans can translate a variety of environmental inputs, including viral infection, famine, and high temperatures, into modifications of some epigenetic elements.”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [100]

    The Introduction and Discussion describe an antiviral response in C. elegans that is carried across generations by virus-derived small RNAs. The paper does not establish famine or high temperatures as environmental triggers of epigenetic changes; its heat shock is used to induce expression of a viral transgene. The claim therefore extends the paper’s finding beyond the input it studied. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • C. elegans converts several environmental stimuli, including viral infection, starvation and elevated temperature, into changes in epigenetic components.

    “C. elegans has been shown to translate several environmental stimuli, such as viral infection, starvation or elevated temperatures, into modification of epigenetic components [77][78][79] .”

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.
