Gene Expression After Exercise Is Disrupted by Early-Life Stress.

Exercise can be leveraged as an important tool to improve neural and psychological health, either on its own or to bolster the efficacy of evidence-based treatment modalities. Research in both humans and animal models shows that positive experiences, such as exercise, promote neuroprotection while, in contrast, aversive experiences, particularly those in early development, are often neurologically and psychologically disruptive. In the current study, we employed a preclinical model to investigate the therapeutic benefits of exercise on gene expression in the brains of adult rats.

Childhood maltreatment exposure (CME) increases the risk of adverse long-term health consequences for the exposed individual. Animal studies suggest that CME may also influence the health and behaviour in the next generation offspring through CME-driven epigenetic changes in the germ line. Here we investigated the associated between early life stress on the epigenome of sperm in humans with history of CME.

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.

Introduction: The development of stress-related psychopathologies, often associated with socio-emotional dysfunctions, is crucially determined by genetic and environmental factors, which shape the individual vulnerability or resilience to stress. Especially early adolescence is considered a vulnerable time for the development of psychopathologies. Various mouse strains are known to age-dependently differ in social, emotional, and endocrine stress responses based on genetic and epigenetic differences.
