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

backgroundBacillus subtilis 3610 displays multicellular traits as it forms structurally complex biofilms and swarms on solid surfaces. In addition, B. subtilis encodes and expresses nitric oxide synthase (NOS), an enzyme that is known to enable NO-mediated intercellular signalling in multicellular eukaryotes. In this study, we tested the hypothesis that NOS-derived NO is involved in the coordination of multicellularity in B. subtilis 3610.

resultsWe show that B. subtilis 3610 produces intracellular NO via NOS activity by combining Confocal Laser Scanning Microscopy with the NO sensitive dye copper fluorescein (CuFL). We further investigated the influence of NOS-derived NO and exogenously supplied NO on the formation of biofilms, swarming motility and biofilm dispersal. These experiments showed that neither the suppression of NO formation with specific NOS inhibitors, NO scavengers or deletion of the nos gene, nor the exogenous addition of NO with NO donors affected (i) biofilm development, (ii) mature biofilm structure, and (iii) swarming motility in a qualitative and quantitative manner. In contrast, the nos knock-out and wild-type cells with inhibited NOS displayed strongly enhanced biofilm dispersal.

conclusionThe results suggest that biofilm formation and swarming motility in B. subtilis represent complex multicellular processes that do not employ NO signalling and are remarkably robust against interference of NO. Rather, the function of NOS-derived NO in B. subtilis might be specific for cytoprotection against oxidative stress as has been proposed earlier. The influence of NOS-derived NO on dispersal of B. subtilis from biofilms might be associated to its well-known function in coordinating the transition from oxic to anoxic conditions. Here, NOS-derived NO might be involved in fine-tuning the cellular decision-making between adaptation of the metabolism to (anoxic) conditions in the biofilm or dispersal from the biofilm.
