Abstract
All living organisms have been programmed to maintain a complex inner equilibrium called homeostasis, despite numerous adversities during their lifespan. Any threatening or perceived as such stimuli for homeostasis is termed a stressor, and a highly conserved response system called the stress response system has been developed to cope with these stimuli and maintain or reinstate homeostasis. The glucocorticoid receptor, a transcription factor belonging to the nuclear receptors protein superfamily, has a major role in the stress response system, and research on its interactome may provide novel information regarding the mechanisms underlying homeostasis maintenance. A list of 149 autosomal genes that have an essential role in GR function or are prime examples of GRE-containing genes was composed in order to gain a comprehensive view of the GR interactome. A search for SNPs on those particular genes was conducted on a dataset of 3554 Japanese individuals, with mentioned polymorphisms being annotated with relevant information from the ClinVar, LitVar, and dbSNP databases. Forty-two SNPs of interest and their genomic locations were identified. These SNPs have been associated with drug metabolism and neuropsychiatric, metabolic, and immune system disorders, while most of them were located in intronic regions. The frequencies of those SNPs were later compared with a dataset consisting of 1465 Korean individuals in order to find population-specific characteristics based on some of the identified SNPs of interest. The results highlighted.that rs1043618 frequencies were different in the two populations, with mentioned polymorphism having a potential role in chronic obstructive pulmonary disease in response to environmental stressors. This SNP is located in the HSPA1A gene, which codes for an essential GR co-chaperone, and such information showcases that similar gene may be novel genomic targets for managing or combatting stress-related pathologies.

Abstract
Posttraumatic stress disorder (PTSD) has been associated with accelerated progression of coronary heart disease (CHD). However, the underlying pathophysiological pathway has remained elusive and it is unclear whether there is a direct link between PTSD and CHD risk. This paper describes the methods of a randomized controlled trial developed to examine how changes in PTSD symptoms affect CHD disease pathways. One hundred twenty participants with current PTSD and who are free of known CHD will be randomized to receive either an evidence-based treatment for PTSD (Cognitive Processing Therapy; CPT) or a waitlist control (WL). Before and after CPT/WL, participants undergo assessment of CHD risk biomarkers reflecting autonomic nervous system dysregulation, systemic inflammation, and vascular endothelial dysfunction. The primary hypothesis is that individuals who show improvement in PTSD symptoms will show improvement in CHD risk biomarkers, whereas individuals who fail to improve or show worsening PTSD symptoms will have no change or worsening in CHD biomarkers. This study is expected to provide knowledge of the role of both the direct impact of PTSD symptoms on CHD risk pathways and the role of these systems as candidate mechanisms underlying the relationship between PTSD and CHD risk. Further, results will provide guidance on the utility of cognitive therapy as a tool to mitigate the accelerated progression of CHD in PTSD.

Abstract
Given the connection between chronic stress and health, there has been a growing emphasis on identifying chronically stressed wild animals, especially in relation to anthropogenic disturbances. There is considerable confusion, however, in how to identify chronically stressed wild animals, but the most common assumption is that measures of glucocorticoid (GC) function will increase. In an attempt to determine an "endocrine profile" of a chronically stressed wild animal, this review collected papers from the literature that measured baseline GC, stress-induced GC, measures of integrated GC, negative feedback, hypothalamic-pituitary-adrenal axis sensitivity, and/or body weight in chronically stressed animals. The collected studies encompassed laboratory and field studies, numerous diverse species, and multiple techniques for inducing chronic stress. Each paper was ranked according to its relevance to wild animals and scored as to whether the measured response increased, decreased, or stayed the same after exposure to chronic stress. The analyses uncovered so much variation between studies that the literature does not support a generalized endocrine profile in how wild animals respond to chronic stress. The common predictions appear to be based almost entirely on theoretical models rather than empirical data. The three most important variables affecting GC responses were the stressors used to induce chronic stress, the potential for those stressors to induce habituation, and the taxon of the focal species. The best approach for identifying a chronically stressed population appears to be documentation of changes at multiple levels of GC regulation, but the direction of the change (increase or decrease) may be relatively unimportant compared to the fact that the response changes at all. The conclusion is that a consistent, predictable, endocrine response to chronic stress, regardless of the protocol used to induce chronic stress and the species under study, does not exist.
