MicroRNAs (miRNAs) are single-stranded, small RNAs (21-23 nucleotides) that function in gene silencing and translational inhibition via the RNA interference mechanism. Most miRNAs originate from host genomic regions, such as intergenic regions, introns, exons, and transposable elements (TEs). Here, we focused on the palindromic structure of medium reiteration frequencies (MERs), which are similar to precursor miRNAs. Five MER consensus sequences (MER5A1, MER53, MER81, MER91C, and MER117) were matched with paralogous transcripts predicted to be precursor miRNAs in the horse genome (equCab2) and located in either intergenic regions or introns...

Hypersexual Disorder (HD) defined as non-paraphilic sexual desire disorder with components of compulsivity, impulsivity and behavioral addiction, and proposed as a diagnosis in the DSM 5, shares some overlapping features with substance use disorder including common neurotransmitter systems and dysregulated hypothalamic-pituitary-adrenal (HPA) axis function. In this study, comprising 67 HD male patients and 39 male healthy volunteers, we aimed to identify HPA-axis coupled CpG-sites, in which modifications of the epigenetic profile are associated with hypersexuality...

BACKGROUND: In recent years, a relationship between depression and basal dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) levels has frequently been suggested, but responses of these adrenal steroids to psychosocial stress have not been examined in individuals with depressive disorders. In this study, we examined salivary DHEA, DHEA-S, and cortisol/DHEA response to the Trier Social Stress Test (TSST) in individuals with depressive disorders and in healthy controls to discover whether the responses of DHEA and DHEA-S to acute psychosocial stress could be a more sensitive marker of HPA dysfunction in depressive disorders...

Brain ischemia inhibits immune function systemically, with resulting infectious complications. Whether in stroke different immune alterations occur in brain and periphery and whether analogous mechanisms operate in these compartments remains unclear. Here we show that in patients with ischemic stroke and in mice subjected to middle cerebral artery occlusion, natural killer (NK) cells display remarkably distinct temporal and transcriptome profiles in the brain as compared to the periphery. The activation of catecholaminergic and hypothalamic-pituitary-adrenal axis leads to splenic atrophy and contraction of NK cell numbers in the periphery through a modulated expression of SOCS3, whereas cholinergic innervation-mediated suppression of NK cell responses in the brain involves RUNX3...

OBJECTIVES/HYPOTHESIS: The function of the human endolymphatic sac (ES) has been enigmatic for decades. Hypotheses include controlling endolymphatic fluid homeostasis and inner ear immunological defense. Additionally, several studies indicate a possible endocrine capacity and a yet undefined role in intracranial pressure homeostasis. However, no direct evidence of such capacity exists. This study aims to explore and identify the hypothesized endocrine capacity of the human ES. STUDY DESIGN: DNA microarrays and immunohistochemistry were used for analyses of fresh human ES tissue samples...

Impaired β-cell function and insufficient β-cell mass compensation are twin pathogenic features that underlie type 2 diabetes (T2D). Current therapeutic strategies continue to evolve to improve treatment outcomes in different ethnic populations and include approaches to counter insulin resistance and improve β-cell function. Although the effects of insulin secretion on metabolic organs such as liver, skeletal muscle and adipose is directly relevant for improving glucose uptake and reduce hyperglycemia, the ability of pancreatic β-cells to crosstalk with multiple non-metabolic tissues is providing novel insights into potential opportunities for improving β-cell function and/or mass that could have beneficial effects in patients with diabetes...

Recent studies have suggested a close association between prenatal maternal distress and allergic diseases in the offspring. We selected relevant birth-cohort or national registry studies using a keyword search of the PubMed database and summarized current evidence on the impact of prenatal maternal distress on the development of offspring's allergic diseases. Moreover, we postulated possible pathways linking prenatal distress and allergic diseases based on relevant human and animal studies. Both dysregulated hypothalamic-pituitary-adrenal axis and increased oxidative stress may cause structural (altered brain/lung development) and functional (skewed immune development) changes, which may predispose the fetus to developing allergic diseases during childhood...

Previous findings on the dysfunction of hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety disorder (GAD) are controversial, and the molecular mechanisms underlying such dysfunction remain unclear. We analyzed the methylation status of the NR3C1 1F promoter and the expression of glucocorticoid receptor-α isoform (GRα) in peripheral blood mononuclear cells (PMBCs), the basal cortisol level in serum, and a functional neuroendocrine marker for GR sensitivity in the PMBCs in 64 patients with current GAD and 85 healthy controls...

Male infants and boys through early adolescence can undergo circumcision either for the sake of upholding religious traditions or for medical reasons. According to both, Jewish as well as Islamic tenets, circumcision is a religious rite symbolizing the bond with God. The World Health Organization (WHO), the United Nations Council (UNC) as well as the American Academy of Pediatrics (AAP), and the Centers for Disease Control and Prevention (CDC) strongly recommend circumcision to promote hygiene and prevent disease...

Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant hereditary familial disorder characterized by development of malignant and benign neoplasms. Differential diagnosis of the adrenal and pancreatic masses are difficult in patients with VHLS. Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and indium-111 somatostatin receptor scintigraphies (In-111 SRS) have important roles in the differential diagnosis of adrenal and pancreatic masses in those patients. In this case report, we present the findings of I-123 MIBG single-photon emission computerized tomography (SPECT/CT) and In-111 SRS SPECT/CT in three members of a family with VHLS...

A lot of data has been accumulated at present on the metabolic and nutritional insufficiency in patients with chronic heart failure (CHF). Researchers have noted an actuality of the study of nutritional and metabolic insufficiency in CHF patients as independent factors affecting the course of CHF and because of its relationship with triggers of inflammation, sympathetic-adrenal system, and markers of functional state of the cardiovascular system (CVS). In some works attention has been given to relationship of nutritional and metabolic insufficiency with autonomic regulation of cardiac rhythm...

The protein α-synuclein has a central role in the pathogenesis of Parkinson's disease. Like that of other proteins that accumulate in neurodegenerative disease, however, the function of α-synuclein remains unknown. Localization to the nerve terminal suggests a role in neurotransmitter release, and overexpression inhibits regulated exocytosis, but previous work has failed to identify a clear physiological defect in mice lacking all three synuclein isoforms. Using adrenal chromaffin cells and neurons, we now find that both overexpressed and endogenous synuclein accelerate the kinetics of individual exocytotic events, promoting cargo discharge and reducing pore closure ('kiss-and-run')...

Several members of the short-chain dehydrogenase/reductase (SDR) enzyme family play fundamental roles in adrenal and gonadal steroidogenesis as well as in the metabolism of steroids, oxysterols, bile acids, and retinoids in peripheral tissues, thereby controlling the local activation of their cognate receptors. Some of these SDRs are considered as promising therapeutic targets, for example to treat estrogen-/androgen-dependent and corticosteroid-related diseases, whereas others are considered as anti-targets as their inhibition may lead to disturbances of endocrine functions, thereby contributing to the development and progression of diseases...

INTRODUCTION: Ectopic adrenal tissue is a very rare entity in adult females, especially in the ovary, and is generally diagnosed incidentally during surgery. Although it can present at various sites during childhood, it becomes atrophic by adulthood due to normally functioning adrenal glands. Patients are predominantly asymptomatic; however, in some cases endocrine symptoms such as hypertension and fasciotruncal obesity due to hormonal activity can be seen or neoplastic transformation can appear...

Chronic breathlessness is a common source of psychological and physical stress in patients with advanced or progressive disease, suggesting that hypothalamic-pituitary-adrenal (HPA) axis dysregulation may be prevalent. The aim of this study was to measure the salivary diurnal cortisol profile in patients receiving supportive and palliative care for a range of malignant and non-malignant conditions and to compare the profile of those experiencing moderate-to-severe disability due to breathlessness against that of patients with mild/no breathlessness and that of healthy controls...

The sympato-adrenal-system and hypothalamus-pituitary-adrenal (HPA) axis are anatomically and functionally connected with participation of several brain areas that express estrogen receptors (ERα and ERβ). We assessed the neuronal activity of these areas for FOS expression and the action of PPT (ERα agonist) or DPN (ERβ agonist) in HPA axis activity during hemorrhagic stress. Ovariectomized Wistar rats treated with vehicle (DMSO) or ER agonists were catheterized for blood collection. Animals received (control) or not (hemorrhagic) immediate reposition with the same volume of saline...

Rapid immersion of a rat's limbs into 4°C water, a model of cold stress (CS), can elicit hemodynamic perturbations (CEHP). We have reported that CEHP is highly relevant to the sympathetic activation and nitric oxide production. This study identifies the role of nitric oxide in CEHP. Conscious rats were pretreated with the nitric oxide synthase inhibitor L-NAME alone or following the removal of sympathetic influences using hexamethonium or guanethidine, and then they were subjected to a 10-min CS trial. Hemodynamic indices were telemetrically monitored throughout the experiment...
