BACKGROUND The age-related decline of dehydroepiandrosterone and its sulfate ester levels is thought to be related to the development of age-associated usual modifications, such as neuromuscular function impairments. It is often claimed that individuals can enhance their muscular capacity by boosting dehydroepiandrosterone levels through oral supplementation. However, to our knowledge, there ha...

To test the hypothesis that insulin acutely enhances the metabolic clearance rate (MCR) of dehydroepiandrosterone in humans, the effect of a short-term insulin infusion on the MCR of dehydroepiandrosterone was assessed in 10 men and 7 women. After an overnight fast, dehydroepiandrosterone was infused at 3.47 mumol/h for 6.5 h. At 240 min, a hyperinsulinemic-euglycemic clamp was begun by infusin...

preeclampsia is a major cause of morbidity and mortality during pregnancy. several independent investigators have demonstrated the association of androgens with hypertension. the main purpose of this study was to determine whether maternal levels of sex hormones, especially testosterone, are higher in patients with preeclampsia than in matched normotensive control subjects. serum levels of test...

Few studies have used longitudinal approaches to consider the cumulative impact of COVID-19-related stressors (CRSs) on psychological adjustment mothers and children. In current study, we tracked changes in maternal depressive symptoms children’s behavioral problems from approximately 2 years before pandemic (T1) May through August 2020 (T2). Second, explored hair cortisol dehydroepiandrosteron...

BACKGROUND The authors sought to examine whether levels of dehydroepiandrosterone are abnormal in depression. METHODS Three groups of subjects aged 20-64 were studied: 44 major depressives, 35 subjects with partially or completely remitted depression, matched as far as possible for age and drug treatment, and 41 normal control subjects. Dehydroepiandrosterone and cortisol in saliva were deter...

Dehydroepiandrosterone and dehydroepiandrosterone sulfate are endogenous steroids largely produced in the adrenal cortex and excreted in the urine. Many studies have demonstrated that administration of dehydroepiandrosterone to animals protects against a variety of chemical carcinogens. Epidemiological studies suggest that the circulating levels of these steroids in humans are related to the ri...

BACKGROUND Survival remains an issue in pulmonary hypertension, a chronic disorder that often affects aged human adults. In young adult mice and rats, chronic 50% hypoxia (11% FIO2 or 0.5 atm) induces pulmonary hypertension without threatening life. In this framework, oral dehydroepiandrosterone was recently shown to prevent and reverse pulmonary hypertension in rats within a few weeks. To eval...

Dehydroepiandrosterone, an adrenal hormone derived from cholesterol, can be metabolized to estrogens (estradiol) and androgens (testosterone). In this study, we evaluated whether the antiproliferative effect induced by dehydroepiandrosterone in MCF-7 cells (an estrogen-dependent breast cancer cell line) is direct, or indirect, through its conversion to estradiol or testosterone. Although dehydr...
