DNMT1 as an environmental sensor: epigenetic pathways linking environmental exposures, sex hormone signaling, and vulnerability to neurodevelopmental and neurodegenerative diseases.
Review in Frontiers in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
DNA methyltransferase 1 (DNMT1) has classically been viewed as the canonical maintenance methyltransferase, yet accumulating evidence positions it as a multifaceted hub that integrates environmental, hormonal, and metabolic signals with chromatin regulation in the developing and adult brain. This review highlights DNMT1 as an environmentally responsive epigenetic sensor across the lifespan. We examine how psychosocial stress, early-life adversity, inflammation, nutritional and microbiome-derived metabolites, and environmental toxicants modulate DNMT1 expression, subcellular localization, and post-translational modifications, thereby reshaping DNA methylation landscapes in neurons and glia. We further discuss how sex hormone signaling, particularly estrogen receptor alpha
