Adult neuroplasticity is strongly influenced by steroids. In particular, corticosterone (CORT) and dehydroepiandrosterone (DHEA) can have opposing effects, where CORT reduces while DHEA increases neurogenesis and neuron recruitment. It has been previously shown that in adult male song sparrows, DHEA treatment increases neuron recruitment throughout the telencephalon, including the lateral ventr...
Dehydroepiandrosterone (DHEA) is important for human health, especially for women. All estrogens and practically half of androgens are synthesized from DHEA in peripheral tissues. However, the mechanism and exact target tissues of DHEA biotransformation in the female are not fully clear. The present study showed that maximal content of androstenedione (AD) and testosterone (T) were observed at ...
Dehydroepiandrosterone (DHEA) and its sulfated form, DHEA-S, peak in young adulthood and then decrease dramatically with age. However, there is extensive variation in this age-related hormone decline, suggesting an early decrement may be associated with lower vitality and be prognostic of poor health in old age. To determine whether DHEA-S and DHEA are correlated with physical indices of vitali...
DHEA is the major precursor of human sex steroid synthesis and is inactivated via sulfonation to DHEAS. A previous genome-wide association study related the single nucleotide polymorphism (SNP) rs2637125, located near the coding region of DHEA sulfotransferase, SULT2A1, to serum DHEAS concentrations. However, the functional relevance of this SNP with regard to DHEA sulfonation is unknown. Using...
The marked decline in serum dehydroepiandrosterone (DHEA) with age is believed to play a role in health problems associated with aging, these health issues being potentially preventable or reversible by the exogenous administration of DHEA. In the present study, liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS) and gas chromatrography/mass spectrometry (GC/MS) were used to me...
INTRODUCTION Rapid and accurate risk stratification in patients with community-acquired pneumonia (CAP) is an unmet clinical need. Cortisol to dehydroepiandrosterone (DHEA) ratio was put forward as a prognostic marker in sepsis. We herein validated the prognostic value of the adrenal hormones DHEA, DHEA-Sulfate (DHEAS), cortisol/DHEA-, cortisol/DHEAS- and DHEA/DHEAS-ratios in patients with CAP....
دی هیدرواپیاندروسترون (DHEA) و مشتق سولفاته آن (DHEA-S)، مهمترین هورمون استروئیدی C19 میباشد که توسط قشر آدرنال ترشح میشود. چنین تصور میشود که میباید همبستگی معکوسی میان آتروژنز از طریق اثر ضد پرولیفراتیو آن موجود باشد؛ ولی در مورد این مطلب گزارشهای ضد و نقیضی وجود دارد. هدف این مطالعه، بررسی اثر DHEA-S بر روی بیماری عروق کرونر قلبی است. در یک مطالعه تصادفی آیندهنگر، 202 فرد با CAD احتمال...
Dehydroepiandrosterone (DHEA), the major steroid precursor of androgens and estrogens produced in peripheral tissues in primates, is an effective chemopreventive agent in the A/-methyl-A/-nitrosourea (MNU)induced rat mammary tumor model. Dietary 1)111 \ (5-600 ppm; 600 mg/kg diet) was administered beginning 1 week before MM and admin istered continually throughout the duration of the experiment...
The adrenal steroid hormone dehydroepiandrosterone (DHEA) and its sulfated derivative [DHEA(S)] have been extensively studied for their potential anti-aging effects. Associated with aging, DHEA levels decline in humans, whereas other adrenal hormones remain unchanged, suggesting that DHEA may be important in the aging process. However, the effect of DHEA(S) supplementation on cardiac function i...
The purpose of this study was to determine whether administration of dehydroepiandrosterone (DHEA) protects male rats against the accumulation of body fat the development of insulin resistance with advancing age. We found that supplementation of the diet with 0.3% DHEA between the ages of 5 months and approximately 25 months resulted in a significantly lower final body weight (DHEA, 593 +/- 18 ...
