An antiviral role for the RNA interference machinery in Caenorhabditis elegans
Open accessAbstract
RNA interference (RNAi) is a sequence-specific gene-silencing mechanism triggered by exogenous dsRNA. In plants an RNAi-like mechanism defends against viruses, but the hypothesis that animals possess a similar natural antiviral mechanism related to RNAi remains relatively untested. To test whether genes needed for RNAi defend animal cells against virus infection, we infected wild-type and RNAi-defective cells of the nematode C. elegans with vesicular stomatitis virus engineered to encode a GFP fusion protein. We show that upon infection, cells lacking components of the RNAi apparatus produce more GFP and infective particles than wild-type cells. Furthermore, we show that mutant cells with enhanced RNAi produce less GFP. Our observation that multiple genes required for RNAi are also required for resistance to vesicular stomatitis virus suggests that the RNAi machinery functions in resistance to viruses in nature.

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.
