Response of P. aeruginosa E(1) gene expression to cadmium stress.
Article in Current microbiology, 2012. 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
Heavy metal resistance microorganism plays an important role on polluted soil bioremediation. To obtain further knowledge of the resistant mechanism employed by cadmium-resistant bacteria, some gene expression profiles at transcription level were investigated in P. aeruginosa E(1) subjected to cadmium stress using real-time PCR. Exposure to cadmium for 1 h, the expression of czcA, czcB, and czcC all reached the peak of up-regulation 8.82-, 4.83-, and 7.43-fold, respectively. The response of czcD was earlier and stronger than czcABC. CysM contributed to cysteine synthesis kept up-regulation within the beginning 2 h. The expression of mgtAE genes related to Mg(2+) influx was up-regulated all the while, znuB responsible for Zn(2+) transportation kept up-regulation from 30 min to 4 h. The result support the two cadmium-resistance mechanisms including effluxing and inactive the heavy metal ions. The mechanism was brought that increase of Mg(2+) and Zn(2+) in cytoplasm would prevent Cd(2+)-binding enzymes to decrease the harm to cell.
