Abstract

Glucocorticoids released from the adrenal gland in response to stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis induce activity in the cellular reduction-oxidation (redox) system. The redox system is a ubiquitous chemical mechanism allowing the transfer of electrons between donor/acceptors and target molecules during oxidative phosphorylation while simultaneously maintaining the overall cellular environment in a reduced state. The objective of this review is to present an overview of the current literature discussing the link between HPA axis-derived glucocorticoids and increased oxidative stress, particularly focussing on the redox changes observed in the hippocampus following glucocorticoid exposure.

  • Chronic prenatal stress produces affective abnormalities together with HPA axis hyperactivity and epigenetic disruptions, illustrating the interplay between inflammation, endocrine function, and chromatin regulation in stress vulnerability.

    “Chronic prenatal stress produces affective abnormalities together with HPA axis hyperactivity and epigenetic disruptions, illustrating the interplay between inflammation, endocrine function, and chromatin regulation in stress vulnerability (Possamai-Della et al., 2023; Glover et al., 2009; Spiers et al., 2014).”

    From Histone modifications and depression: epigenetic mechanisms, therapeutic targets, and translational outlook (2026) · cites this paper as Spiers et al., 2014

    The Introduction describes HPA-axis activation as part of the stress response, and the Adrenal glucocorticoids and oxidative stress section discusses how oxidative conditions can increase HPA-axis activity. Neither passage establishes that chronic prenatal stress produces affective abnormalities, HPA-axis hyperactivity, or epigenetic disruptions; the claimed interplay with inflammation and chromatin regulation is also unsupported by this copy. No page numbers are available in the indexed passages. (LLM, conf=0.82)

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.
