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

Construction of a self-regenerating biochemical system is critical for building a synthetic cell. An essential step in building a self-regenerative system is producing a complete set of tRNAs for translation, which remains a significant challenge. Here, we reconstitute a complete set of 21 in vitro transcribed tRNAs and optimize their abundance to improve protein yield. Next, we show that protein expression in the PURE transcription-translation system can be achieved by in situ transcribing tRNAs from 21 linear tRNA templates or a single plasmid template. To enable synthesis of mature tRNAs from a circular template, we employ either a nicked plasmid template or T. maritima tRNase Z to post-transcriptionally process the precursor tRNAs. We ultimately achieve continuous in situ synthesis of a complete set of tRNAs capable of supporting sustained, steady-state protein expression in PURE reactions running on microfluidic chemostats. Our findings advance the development of an autopoietic biochemical system.
