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

The dimorphic yeast Yarrowia lipolytica has become an emerging cell factory for recombinant proteins production. Expression vectors involving LIP2 promoter (pLIP2) have been developed and used successfully. However, the relationship between dimorphic transition (i.e., cell morphology) and pLIP2 regulation is still unclear and must be assessed to improve process robustness. This requests to discriminate the effect of cell morphology from that of effectors, such as pH, that trigger the dimorphic transition. This was performed using gene reporter system based on β-galactosidase activity and DsRed fluorescence, single-cell analysis by flow cytometry, and quantification of gene expression. Our results clearly pointed out that cell morphology has not effect on the regulation of pLIP2. By contrast, pH modification yielded to phenotypic heterogeneity, potentially leading to a lack of robustness of the cell population. Taken altogether, our results demonstrated that, under appropriate environmental conditions (e.g., pH being an important factor), Y. lipolytica could be considered as a robust and reliable host for recombinant protein production.
