Intérêt thérapeutique de la DHEA ?

, 2007
La DHEA est un androgène, synthétisé par la corticosurrénale des primates. Dans le plasma la forme sulfatée (S-DHEA, 99,8%) est en interconversion avec la forme libre (DHEA, 0,2%) biologiquement active. Les taux circulants, extrêmement élevés, augmentent

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).

Dehydroepiandrosterone [DHEA(S)]: anabolic hormone?.

, 2010
The role of dehydroepiandrosterone (DHEA) and its sulphated form (DHEAS) as anabolic hormones is still debated in the literature. In this review we describe the fundamental steps of DHEA physiological secretion and its peripheral metabolism.

The Effects of the Steroids 5-Androstenediol and Dehydroepiandrosterone and Their Synthetic Derivatives on the Viability of K562, HeLa, and Wi-38 Cells and the Luminol-Stimulated Chemiluminescence of Peripheral Blood Mononuclear Cells from Healthy Volunteers

Biomolecules
In order to evaluate the role of substituents at 3-C and 17-C in the cytotoxic and cytoprotective actions of DHEA and 5-AED molecules, their derivatives were synthesized by esterification using the corresponding acid anhydrides or acid chlorides.

Antioxidation Activity of DHEA and Its Mechanisms

, 2001
Objective: The aim of this study was to determine the anti-oxidative activity of a new chemopreventive agent--dehydroepiandrosterone (DHEA), and the mechanisms of action by which DHEA protect the thymocytes and DNA from oxidative damage. Methods: Agarose

No evidence for hepatic conversion of dehydroepiandrosterone (DHEA) sulphate to DHEA: in vivo and in vitro studies

, 2005
Dehydroepiandrosterone ( DHEA) sulfate (DHEAS) is the most abundant steroid in the human circulation and is thought to be the circulating hydrophilic storage form of DHEA.

In rats, oral oleoyl-DHEA is rapidly hydrolysed and converted to DHEA-sulphate

Background: Dehydroepiandrosterone (DHEA) released by adrenal glands may be converted to androgens and estrogens mainly in the gonadal, adipose, mammary, hepatic and nervous tissue.
