Sequencing and bioinformatics analysis of the metal-related genes in Acidithiobacillus ferrooxidans strain DC.
Article in Folia microbiologica, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Metal-related genes (afe_0654, afe_0671, afe_0674, afe_1143, afe_1144, and afe_2126) were cloned to identify whether those genes existed in Acidithiobacillus ferrooxidans strain DC (A. ferrooxidans DC). The deduced amino acid sequences of those genes were analyzed by bioinformatics. The tolerance levels of A. ferrooxidans DC to Mn(2+), Zn(2+), and Cd(2+) were determined, which were 0.52, 0.42, and 0.16 mol/L for ferrous iron-grown cells and 0.38, 0.18, and 0.08 mol/L for sulfur-grown cells, respectively. Real-time quantitative PCR was employed to analyze the transcriptional levels of the metal-related genes when ferrous iron- and sulfur-grown cells of A. ferrooxidans DC, respectively, exposed to Mn(2+), Zn(2+), and Cd(2+). The metal-related genes were up-regulated when A. ferrooxidans DC exposed to Mn(2+). When A. ferrooxidans DC exposed to Zn(2+), the metal-related genes were up-regulated in sulfur-grown cells; afe_0654 and afe_0674 were down-regulated, and the others were up-regulated in ferrous iron-grown cells. Afe_2126 was down-regulated, and the others were up-regulated when A. ferrooxidans DC exposed to Cd(2+). According to experimental results and bioinformatics analysis, the proteins encoded by afe_0654 and afe_0674 may relate with Mn(2+) and Cd(2+) efflux. It needed further study whether they relate with Zn(2+) transport. Proteins encoded by afe_0671, afe_1143, and afe_1144 may relate with the efflux of Mn(2+), Zn(2+), and Cd(2+). The protein encoded by afe_2126 may relate with Mn(2+) and Zn(2+) efflux and Cd(2+) uptake.
