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

Long-chain acyl-coenzyme A (CoA) synthetases (LACSs) activate free fatty acids to acyl-CoA thioesters and as such play critical roles in fatty acid metabolism. This important class of enzymes factors prominently in several fatty acid-derived metabolic pathways, including phospholipid, triacylglycerol, and jasmonate biosynthesis and fatty acid beta-oxidation. In an effort to better understand the factors that control fatty acid metabolism in oilseeds, we have sought to identify and characterize genes that encode LACSs in Arabidopsis. Nine cDNAs were identified, cloned, and tested for their ability to complement a LACS-deficient strain of yeast (Saccharomyces cerevisiae). Seven of the nine successfully restored growth, whereas two cDNAs encoding putative peroxisomal isoforms did not. Lysates from yeast cells overexpressing each of the nine cDNAs were active in LACS enzyme assays using oleic acid as a substrate. The substrate specificities of the enzymes were determined after overexpression in LACS-deficient Escherichia coli. Most of the LACS enzymes displayed highest levels of activity with the fatty acids that make up the common structural and storage lipids in Arabidopsis tissues. Analysis of the tissue-specific expression profiles for these genes revealed one flower-specific isoform, whereas all others were expressed in various tissues throughout the plant. These nine cDNAs are thought to constitute the entire LACS family in Arabidopsis, and as such, will serve as powerful tools in the study of acyl-CoA metabolism in oilseeds.
