Abstract

Early-life stress induces persistent memory traces on our genes and programs the life-long risk for depression. Epigenetic marking of the arginine vasopressin (AVP) gene by early-life stress in mice underpins sustained expression and increased hypothalamic-pituitary-adrenal axis activity, triggering endocrine and behavioral alterations that are frequent features in depression. This epigenetic memory evolves in two steps coordinated by the epigenetic reader and writer MeCP2. While early derepression of AVP is driven by neuronal activity causing Ca2+/calmodulin kinase-dependent phosphorylation and dissociation of MeCP2, subsequent hypomethylation at the AVP enhancer gradually develops to sustain derepression. In a vicious circle MeCP2 occupancy uncouples from the initial stimulus and leads to the hard-coding of early-life experience at the level of DNA methylation. The sequential order of these events demarcates the transition from a preliminary to a persistent, possibly irreversible, epigenetic memory and thus defines a critical time window for the timely therapy of severe trauma.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
