Evaluation of global gene expression during cold shock in the human pathogen Vibrio vulnificus.
Article in Marine biotechnology (New York, N.Y.), 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Vibrio vulnificus can adapt to cold temperatures by changing the expression profiles of certain genes and their resulting proteins. In this study, the complete V. vulnificus transcriptome was analyzed under cold shock by looking at gene expression changes occurring during the shift from 35°C to 4°C. A DNA microarray-based global transcript profiling of V. vulnificus showed that 165 genes out of 4,488 altered their expression profiles by more than twofold. From 35°C to 10°C, an overall gene repression was observed while changes occurring below 10°C mainly resulted in upregulation. The highest induction observed occurred in two of the five categorized cold-shock genes, cspA and cspB, which showed a complementary expression pattern during cold shock suggesting a homologous role. Other genes showing a significant fold increase included ribosomal genes, protein folding regulators, and membrane genes. Repressions were observed in all orthologous groups. Genes with top fold changes in repression include those coding for catalytic enzymes responsible for non temperature-related stress regulation. These included antioxidants, sugar uptake, and amino acid scavengers. V. vulnificus maintained a high level of cspA and cspB transcripts during the entire experiment suggesting that these class I cold-shock genes are required beyond the initial phase of the acclimation period.
