Abstract

Significance: One of the goals of modern molecular medicine is delivery and expression of heterologous genes in living organisms. RNA-based delivery vectors are a safer choice than DNA vectors, but they are prone to degradation and are highly dependent on efficient delivery methods. One of the ways to improve RNA vector performance is to increase the level of expression of the encoded proteins. We followed this approach and modified standard alphavirus replicon-based expression systems to make the transcribed subgenomic RNA additionally amplifiable by viral replication enzymes. Higher levels of subgenomic RNA synthesis increased the replicons’ expression efficiency at least 10-fold. Such replicons can be widely applied for development of efficient DNA and RNA vaccines and protein production in vitro.

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.
