Tethering Ribozymes to a Retroviral Packaging Signal for Destruction of Viral RNA
Abstract
Cellular compartmentalization of RNAs is thought to influence their susceptibility to ribozyme cleavage. As a test of this idea, two retroviral vectors—one encoding a hammer-head ribozyme designed to cleave lacZ transcripts and another encoding the lacZ messenger RNA—were coexpressed inside retroviral packaging cells. Because of the retroviral packaging signal, the ribozyme would be expected to colocalize with the lacZ -containing viral genomic RNA but not with the lacZ messenger RNA. The ribozyme was found to reduce the titer of infectious virus containing lacZ by 90 percent, but had no effect on translation of lacZ messenger RNA. These results indicate that sorting gene inhibitors to appropriate intracellular sites may increase their effectiveness.

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.
