Epigenetic modifications and NF-κB pathway activity in Cu,Zn-SOD-deficient mice.
Article in Molecular and cellular biochemistry, 2014. 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
The aim of this study was to examine the possible impact of Cu,Zn-SOD deficiency on the level of epigenetic modifications in different mouse tissues, and the relationship between these modifications and the NF-κB transcription factor activity. Cu,Zn-SOD deficiency did not influence the level of 5mdC or 5hmdC in the analyzed tissues. Statistically significant organ-/tissue-specific differences between the levels of 5mdC and 5hmdC were demonstrated within each genotype. Also correlations between analyzed parameters pointed to wide tissue/genotype variety; we observed a positive correlation between 5mdC and NF-кB proteins, p50 and RelA, in the liver of wild mice, as well as an inverse correlation between 5mdC and p65 in the brain of Cu,Zn-SOD-deficient animals. Moreover, a positive correlation was revealed between 5mdC and 5hmdC in the liver and brain of knockout mice. As the highest levels of both 5mdC and 5hmdC were observed in the brains of analyzed animals regardless of their genotype, and lower, comparable to each other, levels of these modifications were shown in the kidney and liver, active demethylation process seems to be tissue-/organ-specific and does not necessarily rely solely on the redox/oxidation state of cells. According to the most likely scenario, various tissues may differ in terms of their metabolic rates, which has potential influence on cofactors, and consequently on the activity of TET enzymes or activation of TET-independent mechanisms.
