Characterization of histone modifications associated with DNA damage repair genes upon exposure to gamma rays in Arabidopsis seedlings.
Article in Journal of radiation research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Dynamic histone modifications play an important role in controlling gene expression in response to various environmental cues. This mechanism of regulation of gene expression is important for sessile organisms, like land plants. We have previously reported consistent upregulation of various marker genes in response to gamma rays at various post-irradiation times. In the present study, we performed various chromatin modification analyses at selected loci using the standard chromatin immunoprecipitation procedure, and demonstrate that upregulation of these genes is associated with histone H3 lysine 4 tri-methylation (H3K4me3) at the gene body or transcription start sites of these loci. Further, at specific AtAgo2 loci, both H3K4me3 and histone H3 lysine 9 acetylation (H3K9ac) are important in controlling gene expression in response to gamma irradiation. There was no change in DNA methylation in these selected loci. We conclude that specific histone modification such as H3K4me3 and H3K9ac may be more important in activating gene expression in these selected loci in response to gamma irradiation than a change in DNA methylation.
