Early Stress Evokes Age-Dependent Biphasic Changes in Hippocampal Neurogenesis, Bdnf Expression, and Cognition
Open accessAbstract
Background Adult-onset stressors exert opposing effects on hippocampal neurogenesis and cognition, with enhancement observed following mild stress and dysfunction following severe chronic stress. While early life stress evokes persistent changes in anxiety, it is unknown whether early stress differentially regulates hippocampal neurogenesis, trophic factor expression, and cognition across the life span.Methods Hippocampal-dependent cognitive behavior, neurogenesis, and epigenetic regulation of brain-derived neurotrophic factor (Bdnf) expression was examined at distinct time points across the life span in rats subjected to the early stress of maternal separation (ES) and control groups. We also examined the influence of chronic antidepressant treatment on the neurogenic, neurotrophic, and cognitive changes in middle-aged ES animals.Results Animals subjected to early stress of maternal separation examined during postnatal life and young adulthood exhibited enhanced hippocampal neurogenesis, decreased repressive histone methylation at the Bdnf IV promoter along with enhanced BDNF levels, and improved performance on the stress-associated Morris water maze. Strikingly, opposing changes in hippocampal neurogenesis and epigenetic regulation of Bdnf IV expression, concomitant with impairments on hippocampal-dependent cognitive tasks, were observed in middle-aged ES animals. Chronic antidepressant treatment with amitriptyline attenuated the maladaptive neurogenic, epigenetic, transcriptional, and cognitive effects in middle-aged ES animals.Conclusions Our study provides novel insights into the short- and long-term consequences of ES, demonstrating both biphasic and unique, age-dependent changes at the molecular, epigenetic, neurogenic, and behavioral levels. These results indicate that early stress may transiently endow animals with a potential adaptive advantage in stressful environments but across a life span is associated with long-term deleterious effects.

In the citing paper
“middle-aged rats that experienced early maternal separation exhibited impaired cognition, reduced H3K9me2 regulation of the BDNF expression, and opposite changes in the hippocampal neurogenesis, suggesting both biphasic and distinct, age-dependent changes in the histone methylation in response to ES.169”

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.
