Trichloroethylene exposure alters dimethylated histone three lysine four in protein kinase A signaling pathway chromatin of rat sperm†.

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
Histone three lysine four dimethylation (H3k4me2) in sperm is conserved across species and is linked to transgenerational epigenetic inheritance. To test whether H3K4me2 is a target for transgenerational inheritance of toxicity, a daily gavage bolus exposure of trichloroethylene (TCE) (1000 mg/kg/day) was given to rats for 14 weeks, then epididymal sperm were isolated and native chromatin immunoprecipitation followed by next generation sequencing (ChIP-seq) of H3K4me2 was performed. Differential region analysis determined there were 2608 significantly differential H3K4me2 regions after TCE exposure, 477 were significantly increased and 2131 were significantly decreased. Z-score enrichment of differential regions determined there were significantly decreased H3k4me2 in the coding and regulatory regions of genes in the PKA signaling pathway. These changes account for TCE induced spermatozoal toxicity and show H3K4me2 is a target for paternal inheritance of toxicity.
