Persistent open chromatin state in early-life stress-activated cells of the VTA.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Early-life stress sensitizes individuals to subsequent stressors to increase lifetime risk for psychiatric disorders. Within the ventral tegmental area (VTA), a mesolimbic brain region implicated in stress response and mental health, early-life stress causes long-lasting changes in gene expression and chromatin modifications that in turn cause latent physiological and behavioral sensitivity to stress. These molecular consequences of early-life stress are indicative of epigenetic priming, a form of molecular memory in which developmental or environmental cues open chromatin at enhancers to facilitate transcriptional response to stimuli. However, the long term impact of early-life stress on chromatin architecture in the VTA was not yet known. Using a combination of activity-dependent cellular tagging and ATAC-sequencing, we find that early-life stress opens chromatin specifically in stress-activated cells of the VTA, that this remodeling persists into adulthood, and that opening chromatin at cis-regulatory elements including enhancers augments transcriptional response to adult stress. Together, this data supports enhancer priming within ELS-responsive cells in the VTA as a biological mechanism for lifelong stress sensitivity.
