Coregulation of gene expression by sigma factors RpoE and RpoS in Salmonella enterica serovar Typhi during hyperosmotic stress.
Article in Current microbiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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.
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
Salmonella enterica serovar Typhi (S. Typhi) is the cause of typhoid fever, a food-borne disease that is prevalent worldwide, most particularly in developing countries. RNA polymerase sigma factors RpoE (σ(E)) and RpoS (σ(S)) govern transcription initiation of two sets of genes in Escherichia and Salmonella. It was previously suggested that some genes might be coregulated by RpoE and RpoS in Salmonella under conditions of environmental stress, but experimental evidence has been lacking. We therefore constructed rpoS deletion (ΔrpoS) and double rpoE/rpoS deletion (ΔrpoE/ΔrpoS) mutants of S. Typhi and compared their growth properties with an rpoE mutant (ΔrpoE) and wild-type strains under conditions of hyperosmotic stress. We report that the ΔrpoE, ΔrpoS, and ΔrpoE/ΔrpoS strains grew more slowly under hyperosmotic stress conditions than the wild-type strain, and the ΔrpoE/ΔrpoS strain grew most slowly. The global transcriptional profiles of ΔrpoE, ΔrpoS, ΔrpoE/ΔrpoS after 30 min of hyperosmotic stress were investigated using a Salmonella genomic DNA microarray. The results of microarray indicated that the expression levels of 38 genes were markedly reduced during hyperosmotic stress in the double mutant ΔrpoE/ΔrpoS strain, but expression levels were not significantly affected by single ΔrpoE or ΔrpoS mutations. This was confirmed for several key genes by qRT-PCR. This study therefore indicated crosstalk between sigma factors RpoE and RpoS in S. Typhi under hyperosmotic conditions and provides new insights into the regulatory networks of S. Typhi.
