SigmaB-dependent and sigmaB-independent mechanisms contribute to transcription of Listeria monocytogenes cold stress genes during cold shock and cold growth.

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
The role of the stress response regulator sigma(B) (encoded by sigB) in directing the expression of selected putative and confirmed cold response genes was evaluated using Listeria monocytogenes 10403S and an isogenic DeltasigB mutant, which were either cold shocked at 4 degrees C in brain heart infusion (BHI) broth for up to 30 min or grown at 4 degrees C in BHI for 12 days. Transcript levels of the housekeeping genes rpoB and gap, the sigma(B)-dependent genes opuCA and bsh, and the cold stress genes ltrC, oppA, and fri were measured using quantitative reverse transcriptase PCR. Transcriptional start sites for ltrC, oppA, and fri were determined using rapid amplification of cDNA ends PCR. Centrifugation was found to rapidly induce sigma(B)-dependent transcription, which necessitated the use of centrifugation-independent protocols to evaluate the contributions of sigma(B) to transcription during cold shock. Our data confirmed that transcription of the cold stress genes ltrC and fri is at least partially sigma(B) dependent and experimentally identified a sigma(B)-dependent ltrC promoter. In addition, our data indicate that (i) while sigma(B) activity is induced during 30 min of cold shock, this cold shock does not induce the transcription of sigma(B)-dependent or -independent cold shock genes; (ii) sigma(B) is not required for L. monocytogenes growth at 4 degrees C in BHI; and (iii) transcription of the putative cold stress genes opuCA, fri, and oppA is sigma(B) independent during growth at 4 degrees C, while both bsh and ltrC show growth phase and sigma(B)-dependent transcription during growth at 4 degrees C. We conclude that sigma(B)-dependent and sigma(B)-independent mechanisms contribute to the ability of L. monocytogenes to survive and grow at low temperatures.
