Chronic Stress Promotes Tumor Growth Through Increased Bdnf Production and Neo-Innervation
… sympathetic nervous system (SNS) in response to chronic biobehavioral stress results in high levels of catecholamines and persistent activation of adrenergic signaling, which promotes tumor growth and progression. However it is unknown how catecholamine levels within the tumor exceed systemic …

CHRONIC STRESS REVEALS COGNITIVE IMPAIRMENT IN A SUBTHRESHOLD AMYLOID-BETA MODEL OF ALZHEIMER’S DISEASE
… genetic factors, environmental factors, such as stress, may also play a critical role in the manifestation of AD. Epidemiological studies indicate that individuals suffering from chronic stress are at an increased risk for developing AD. The present study investigated the effect of chronic …

Truncated Tyrosine Kinase Receptor B (TrkB.T1) plays a role in susceptibility to chronic stress
… effects that may be relevant for dealing with stressors. Using mice lacking TrkB.T1 exposed to chronic stress, we assessed behavioral and TrkB expression profiles, as well as gut-microbial profile. Our results showed that while repeated different stressor regimen did markedly alter open-field …

Investigating systemic effects of chronic stress on hepatic and cardiac tissue in female Wistar rats
Chronic psychosocial stress contributes to cardiometabolic disease onset and progression through various mechanisms including through HPA-axis dysregulation, inflammation, oxidative stress, and autophagic impairment. Growing evidence suggests females may be disproportionately vulnerable to these …

The Manipulation Of Apical Dendritic Plasticity And The Consequences For The Effects of Chronic Stress
… rats collapse in size and complexity following chronic stress. These dendrites return to control sizes with a recovery period. This suggests that dendritic remodeling can function as a protective response mechanism, protecting the region from exposure to the increased amounts of excitatory amino …

The Role Of Chronic Stress In Age Gradients Of Preterm Birth Among Racial/ethnic Groups
Recently, chronic stress has drawn great attention as an underlying mechanism of preterm birth (PTB) among racial/ethnic minority women. However, the association between chronic stress and PTB is not clearly understood. In fact, existing chronic stress models do not agree on definitions and …

Chronic stress-dependent activation of somatostatin neurons in the nucleus accumbens facilitates maladaptive eating behaviors
Stressors are known to impact eating behaviors. However, recapitulating the intricate interplay between chronic stress and aberrant human eating patterns in an animal model remains a challenge. Notably, binge eating, a diagnostic feature associated with many types of eating abnormalities, …

Viral delivery of recombinant growth hormone to rescue effects of chronic stress on hippocampal learning
Chronic stress has been linked to variation in gene regulation in the hippocampus (HIP) among other areas. These lead to cytoskeletal and volumetric rearrangements in various nuclei of the central nervous system and are thought to contribute to several stress-sensitive disorders. One such gene that …
