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

Previously, we demonstrated triacylglycerol (TAG) accumulation and the in vivo ability to catalyze esters from exogenous short chain alcohol sources in Gordonia sp. strain KTR9. In this study, we investigated the effects that putative lipase (KTR9_0186) and wax ester synthase/acyl-CoA:diacylglycerol acyltransferase (WS/DGAT; KTR9_3844) gene knockouts had on TAG accumulation. Gene disruption of KTR9_0186 resulted in a twofold increase in TAG content in nitrogen starved cells. Lipase mutants subjected to carbon starvation, following nitrogen starvation, retained 75 % more TAGs and retained pigmentation. Transcriptome expression data confirmed the deletion of KTR9_0186 and identified the up-regulation of key genes involved in fatty acid degradation, a likely compensatory mechanism for reduced TAG mobilization. In vitro assays with purified KTR9_3844 demonstrated WS/DGAT activity with short chain alcohols and C16 and C18 fatty acid Co-As. Collectively, these results indicate that Gordonia sp. KTR9 has a suitable tractable genetic background for TAG production as well as the enzymatic capacity to catalyze fatty acid esters from short chain alcohols.
