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

We have developed a gene disruption system in the hyperthermophilic archaeon Thermococcus kodakaraensis using the antibiotic simvastatin and a fusion gene designed to overexpress the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase gene (hmg(Tk)) with the glutamate dehydrogenase promoter. With this system, we disrupted the T. kodakaraensis amylopullulanase gene (apu(Tk)) or a gene cluster which includes apu(Tk) and genes encoding components of a putative sugar transporter. Disruption plasmids were introduced into wild-type T. kodakaraensis KOD1 cells, and transformants exhibiting resistance to 4 microM simvastatin were isolated. The transformants exhibited growth in the presence of 20 microM simvastatin, and we observed a 30-fold increase in intracellular HMG-CoA reductase activity. The expected gene disruption via double-crossover recombination occurred at the target locus, but we also observed recombination events at the hmg(Tk) locus when the endogenous hmg(Tk) gene was used. This could be avoided by using the corresponding gene from Pyrococcus furiosus (hmg(Pf)) or by linearizing the plasmid prior to transformation. While both gene disruption strains displayed normal growth on amino acids or pyruvate, cells without the sugar transporter genes could not grow on maltooligosaccharides or polysaccharides, indicating that the gene cluster encodes the only sugar transporter involved in the uptake of these compounds. The Deltaapu(Tk) strain could not grow on pullulan and displayed only low levels of growth on amylose, suggesting that Apu(Tk) is a major polysaccharide-degrading enzyme in T. kodakaraensis.
