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

Growth-mediated dilution can destabilize synthetic gene circuits by reducing intracellular concentrations of key regulatory proteins. Here, we present a protocol that uses liquid-liquid phase separation to buffer dilution of transcription factors and stabilize synthetic gene circuits in E. coli. We describe steps for constructing phase-separating self-activation circuits, characterizing condensate material properties by fluorescence recovery after photobleaching, and imaging of condensate-promoter colocalization. We outline single-cell microscopy and population-level plate reader assays to quantify circuit activation, growth-coupled dilution dynamics, and memory retention. For complete details on the use and execution of this protocol, please refer to Zhang et al.
