Staphylococcus aureus α-hemolysin induces DNA methylation changes in human Th1 cells.

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
α-Hemolysin is one of the most dangerous virulence factors produced by Staphylococcus aureus. Among the immune cells that respond to this pathogenic bacterium, Th1 lymphocytes play a critical role. In our study, we investigated the impact of α-hemolysin on the methylation of the Th1 cell genome. Our findings revealed that α-hemolysin upregulates HELLS and DNMT3A expression while downregulating DNMT3L expression at the protein level. Whole-genome bisulfite sequencing analysis revealed significant alterations in DNA methylation, particularly in regions outside CpG sequences. These results suggest that bacterial proteins can act as potent epigenetic modulators in human cells, influencing their activity, plasticity, and phenotype.
