1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

We recently developed an orthogonal DNA replication (OrthoRep) system capable of driving the rapid continuous evolution of genes in vivo. However, OrthoRep uses a special transcription system, the components of which (e.g., promoters) have previously limited the strength with which OrthoRep-encoded genes can be expressed. Here, we report a collection of synthetic and evolved OrthoRep expression parts that allow OrthoRep-encoded genes to span expression levels matching those of endogenous Saccharomyces cerevisiae genes. Specifically, we found that various promoter mutations as well as a genetically encoded poly(A) tail enable us to tune the expression level of OrthoRep-encoded genes over a large range and up to levels 43-fold higher than were previously attained, reaching at least ∼40% of the strength of the genomic TDH3 promoter. We further show that expression level gains using our new parts are stable over passaging and consistent across multiple genes and OrthoRep systems of different mutation rates. This new set of expression parts further expands OrthoRep's applicability to the continuous in vivo evolution of proteins and pathways.
