BACKGROUND: Children born small for gestational age (SGA) have higher serum dehydroepiandrosterone sulfate (DHEAS) concentrations than children born appropriate for gestational age (AGA). The overall metabolic risk associated with birth weight is U-shaped, but it is not known if children born large for gestational age (LGA) have elevated serum DHEAS levels. METHODS: A cohort of 49 LGA, 56 AGA, and 23 SGA children were studied at 5-8 years of age. Anthropometric data at birth, at the age of two years, and at examination were recorded...

Sexual health severely decreases with age. For males older than 40 years, erectile dysfunction (ED) is the most common sexual disorder. Although physical and psychological risk factors for ED have been identified, protective factors are yet to be determined. To date, no study has examined endocrine and psychosocial factors in parallel with regard to their modifying effect on the age-related increase in ED. Two hundred and seventy-one self-reporting healthy men aged between 40 and 75 years provided both psychometric data on sexual function and a set of potential psychosocial protective factors, and saliva samples for the analysis of steroid hormones and proinflammatory cytokines...

The main hypothesis of the study is that stress associated with repeated immune challenge has an impact on β3-adrenergic receptor gene expression in the brain. Sprague-Dawley rats were intraperitoneally injected with increasing doses of lipopolysaccharide (LPS) for 5 consecutive days. LPS treatment was associated with body weight loss and increased anxiety-like behavior. In LPS-treated animals of both sexes, β3-receptor gene expression was increased in the prefrontal cortex but not the hippocampus. LPS treatment decreased β3-receptor gene expression in white adipose tissue with higher values in males compared to females...

There has been strong interest, spanning several disciplines, in understanding adolescence as a developmental period of increased risk-taking behavior. Our goals focus on one line of investigation within this larger developmental risk framework. Specifically, we examined levels of pubertal hormones in girls in relation to their willingness to take greater financial risks to gain social status. To this end, we tested the hypothesis that higher levels of testosterone during the ages of pubertal maturation are associated with a greater willingness to sacrifice money for social admiration...

The androgen dehydroepiandrosterone (DHEA) responds to stress activation, exhibits anti-glucocorticoid properties, and modulates immunity in diverse ways, yet little is known of its role in acute stress responses. In this study, the effects of DHEA and its sulfate ester DHEA-S on human male immune function during exposure to an acute stressor is explored. Variation in DHEA, DHEA-S, testosterone, and cortisol, along with bacterial killing assays, was measured in response to a modified Trier Social Stress test in 27 young adult males...

In the Canadian Armed Forces (CAF), Conduct After Capture (CAC) training is a 4-day captivity survival course during which soldiers are exposed to increasing stress, and evaluated on their ability to accomplish military objectives. We hypothesized that: (a) compared to baseline, CAC training would cause significant, reversible perturbations in measures of psychological functioning and serum and salivary stress hormone levels relevant to models of stress hardiness and vulnerability; and (b) deviations from baseline would be maximal at the time point of most intense stress during training...

This study investigated the abnormal expression of ATP synthase β-subunit (ATPsyn-β) in pancreas islets of rat model of polycystic ovary syndrome (PCOS) with type 2 diabetes mellitus (T2DM), and the secretion function changes after up-regulation of ATP5b. Sixty female SD rats were divided into three groups randomly and equally. The rat model of PCOS with T2DM was established by free access to the high-carbohydrate/high-fat diet, subcutaneous injections of DHEA, and a single injection of streptozotocin. The pancreas was removed for the detection of the ATPsyn-β expression by immunohistochemical staining, Western blotting and reverse transcription-PCR (RT-PCR)...

Germline variation in solute carrier organic anion (SLCO) genes influences cellular steroid uptake and is associated with prostate cancer (PCa) outcomes. We hypothesized that, due to its steroidal structure, the CYP17A inhibitor abiraterone may undergo SLCO-mediated transport and that SLCO gene variation may influence intracellular abiraterone levels and outcomes.<br /><br />Experimental Design: Steroid and abiraterone levels were measured by mass spectrometry in serum and tissue from 58 men with localized PCa in a clinical trial of LHRH agonist plus abiraterone acetate plus prednisone for 24 weeks prior to prostatectomy...

Invasive epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy. The etiology of EOC remains elusive; however, experimental and epidemiologic data suggest a role for hormone-related exposures in ovarian carcinogenesis and risk factor differences by histologic phenotypes and developmental pathways. Research on pre-diagnosis androgen concentrations and EOC risk has yielded inconclusive results, and analyses incorporating EOC subtypes are sparse. We conducted a pooled analysis of 7 nested case-control studies in the Ovarian Cancer Cohort Consortium to investigate the association between pre-diagnosis circulating androgens (testosterone, free testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEAS)), sex hormone binding globulin (SHBG), and EOC risk by tumor characteristics (i...

PURPOSE: Obesity in fertile women has negative effect on fertility. Anti-mullerian hormone (AMH) represents a good index of fertility, and it is considered a marker of ovarian reserve and of polycystic ovarian syndrome (PCOS) gravity. Previous studies evaluated the relationship between obesity and AMH with contradictory results. The aim of the study was to investigate the relationship between obesity and AMH and the changes of AMH in obese women in reproductive age submitted to bariatric surgery...

Dehydroepiandrosterone (DHEA) can counteract the activity of cortisol by modulating the glucocorticoid receptor β (GRβ) expression and antagonizing the binding of GRα to the glucocorticoid responsive element (GRE) in RACK1 (Receptor for Activated C Kinase 1) promoter. These observations are important in the context of immunosenescence and can be extended to recognize a complex hormonal balance in the control of GR isoform expression and consequently in the expression of GR responsive genes. To elucidate the mechanism of DHEA on GR alternative splicing, we investigated its possible involvement in the expression of proteins such as the Serine/arginine (SR)-Rich Splicing Factors (SRSF) regulating GR splicing, specifically SRSF9 and SRSF3 also known as SRp30c and SRp20 respectively...

Androgen exposure of the fetus during gestation plays an important role in human physiology and pathophysiology, but assessment of androgens, in particular dihydrotestosterone (DHT), in human umbilical cord blood is technically challenging. The aim of this study was to assess umbilical cord androgen levels, including DHT, at birth by a highly sensitive assay, and study their association with sex of the infant, sex-hormone-binding globulin (SHBG) levels, and gestational age at delivery. Swedish infants (27 girls, 26 boys) were recruited at maternity care clinics in Southern Sweden...

Context: Whether primary aldosteronism (PA) is the consequence of a monoclonal or multiclonal process is unclear. Case Description: A 48-year-old man with severe bilateral PA refractory to medical therapy underwent unilateral adrenalectomy of the dominant adrenal. Although computed tomography (CT) showed three left-sided cortical nodules, post-surgical histopathology and genetic analysis revealed five different adrenocortical adenomas. Two zona fasciculata (ZF)-like aldosterone producing adenomas (APAs) each harbored distinct known somatic KCNJ5 mutations (L168R and T158A)...

This study examined the relationships among polymorphisms of the STS gene and SULT2A1 gene, dehydroepiandrosterone (DHEA) and its sulfated form (DHEA-S), and characteristics of attention-deficit/hyperactivity disorder (ADHD). We used cheek swabs to obtain the genomic DNA of 200 ADHD male probands (mean age: 8.7 years), 192 patients' mothers and 157 patients' fathers. Three SNPs in the STS gene (rs6639786, rs2270112, and rs17268988) and one SNP in the SULT2A1 gene (rs182420) were genotyped. Saliva samples were collected from the ADHD patients to analyze DHEA and DHEA-S levels...
