2021-08 Turcu AF, Zhao L, Chen X, Yang R, Rege J, Rainey WE, Veldhuis JD, Auchus RJ

Many hormones display distinct circadian rhythms, driven by central regulators, hormonal bioavailability, and half-life. A set of 11-oxygenated C19 steroids (11-oxyandrogens) and pregnenolone sulfate (PregS) are elevated in congenital adrenal hyperplasia and other disorders, but their circadian patterns have not been characterized.

DHEA as a Biomarker of Stress: A Systematic Review and Meta-Analysis

2021-07 Dutheil F, de Saint Vincent S, Pereira B, Schmidt J, Moustafa F, Charkhabi M , Bouillon-Minois JB, Clinchamps M

Psychosocial stress is a significant public health problem inducing consequences for quality of life. Results about the use of dehydroepiandrosterone (DHEA) as a biomarker of acute stress are conflicting. We conducted a systematic review and meta-analysis to demonstrate that DHEA levels could be a biomarker of stress.

DHEA-pretreatment attenuates oxidative stress in kidney-cortex and liver of diabetic rabbits and delays development of the disease

2021-06 Kiersztan A, Gaanga K, Witecka A, Jagielski AK

In view of reported discrepancies concerning antioxidant activity of dehydroepiandrosterone (DHEA), a widely used dietary supplement, the current investigation was undertaken to evaluate the antioxidant properties of DHEA in both kidney-cortex and liver of alloxan (ALX)-induced diabetic rabbits, as this diabetogenic compound exhibits the ROS-dependent action.

Low neuroactive steroids identifies a biological subtype of depression in adults with human immunodeficiency virus on suppressive antiretroviral therapy

2021-05 Mukerji SS, Misra V, Lorenz DR, Chettimada S, Keller K, Letendre S, Ellis RJ, Morgello S, Parker RA, Gabuzda D

The prevalence and mortality risk of depression in people with human immunodeficiency virus (HIV) infection receiving antiretroviral therapy (ART) is higher than in the general population, yet biomarkers for therapeutic targeting are unknown. In the current study, we aimed to identify plasma metabolites associated with depressive symptoms in people with HIV receiving ART.

Osteoblasts generate testosterone from DHEA and activate androgen signaling in prostate cancer cells

2021-04 Moon HH, Clines KL, O'Day PJ, Al-Barghouthi BM, Farber EA, Farber CR, Auchus RJ, Clines GA

Bone metastasis is a complication of prostate cancer in up to 90% of men afflicted with advanced disease. Therapies that reduce androgen exposure remain at the forefront of treatment. However, most prostate cancers transition to a state whereby reducing testicular androgen action becomes ineffective.

DHEA inhibits proliferation, migration and alters mesenchymal-epithelial transition proteins through the PI3K/Akt pathway in MDA-MB-231 cells

2021-04 Colín-Val Z, López-Díazguerrero NE, López-Marure R

Cancer is one of the leading causes of death worldwide, and breast cancer is the most common among women. Dehydroepiandrosterone (DHEA), the most abundant steroid hormone in human serum, inhibits proliferation and migration of breast cancer cells, modulating the expression of proteins involved in mesenchymal-epithelial transition (MET). However, the underlying molecular mechanisms are not fully understood. 

Circulating levels of sex steroid hormones and gastric cancer

2021-03 Leal YA, Song M, Zabaleta J, Medina-Escobedo G, Caron P, Lopez-Colombo A, Guillemette C, Camargo MC

Men develop gastric cancer more frequently than women, yet little is known about the mechanisms underlying this sex difference. Sex steroid hormones may influence gastric cancer risk. We therefore assessed whether major circulating adrenal precursors, androgens and estrogens were associated with gastric cancer in a high-risk Mexican population.

Blood Dehydroepiandrosterone and Dehydroepiandrosterone Sulfate as pathophysiological correlates of chronic pain: analyses using a national sample of midlife adults in the united states

2021-02 Li R, Chapman BP, Smith SM

Identifying biomarkers is a priority in translational chronic pain research. Dehydroepiandrosterone (DHEA) and its sulfated form, DHEA-S, are adrenocortical steroids in the blood with neuroprotective properties that also produce sex hormones. They may capture key sex-specific neuroendocrine mechanisms of chronic pain.

Impact of dehydroepiandrosterone (DHEA) supplementation on testosterone concentrations and BMI in elderly women: a meta-analysis of randomized controlled trials

2021-01 Hu Y, Wan P, An X, Jiang G

Despite the fact that numerous clinical studies have evaluated the positive effects of dehydroepiandrosterone (DHEA) supplementation on testosterone concentrations and on the body mass index (BMI), more evidence is needed to certify that DHEA is a BMI-reducing agent in the elderly. This meta-analysis aims to clarify the various incompatible results and investigate the impact of DHEA supplementation on serum testosterone levels and lean body mass in elderly women.

The influence of dehydroepiandrosterone (DHEA) on fasting plasma glucose, insulin levels and insulin resistance (HOMA-IR) index: a systematic review and dose response meta-analysis of randomized controlled trials

2020-12 Wang X, Feng H, Fan D, Zou G, Han Y, Liu L

The effect of DHEA supplementation on fasting plasma glucose (FPG), insulin levels (IN) and the homeostasis model assessment-estimated insulin resistance (HOMA-IR) index in humans has not been assessed so far. Thus, we aimed to conduct a systematic review and meta-analysis of the randomized controlled trials (RCT) which assessed the effects of DHEA supplementation on FPG, IN and the HOMA-IR index in humans.

The effects of dehydroepiandrosterone (DHEA) supplementation on body composition and blood pressure: a meta-analysis of randomized clinical trials

2020-11 Wang F, He Y, O Santos H, Sathian B, C Price J, Diao J

Dehydroepiandrosterone (DHEA) supplementation has been anecdotally considered as a tool to improve body composition and health status. We aimed to verify the impact of DHEA supplementation on traditional measurements of body composition and blood pressure (BP) due to their clinical applicability.

Associations between androgens and sexual function in premenopausal women: a cross-sectional study

2020-08 Zheng J, Islam RM, Skiba MA, Bell RJ, Davis SR

Although clinicians often measure the serum concentration of androgens in premenopausal women presenting with sexual dysfunction, with some women given testosterone or dehydroepiandrosterone as treatment if their concentrations are low, whether androgens are determinants of sexual function in women of reproductive age is uncertain. We aimed to clarify the associations between androgens and sexual function in a community-based sample of non-health-care-seeking women.

Impact of dehydroepianrosterone (DHEA) supplementation on serum levels of insulin-like growth factor 1 (IGF-1): a dose-response meta-analysis of randomized controlled trials

2020-07 Xie M, Zhong Y, Xue Q, Wu M, Deng X, O Santos H, Tan SC, Kord-Varkaneh H, Jiao P

Inconsistencies exist with regard to the influence of dehydroepiandrosterone (DHEA) supplementation on insulin-like growth factor 1 (IGF-1) levels. The inconsistencies could be attributed to several factors, such as dosage, gender, and duration of intervention, among others. To address these inconsistencies, we conducted a systematic review and meta-analysis to combine findings from randomized controlled trials (RCTs) on this topic.

Very High Dehydroepiandrosterone Sulfate (DHEAS) in serum of an overweight female adolescent without a tumor

2020-05 Iliev DI, Braun R, Sánchez-Guijo A, Hartmann M, Wudy SA, Heckmann D, Bruchelt G, Rösner A, Grosser G, Geyer J, Binder G

An increase of serum dehydroepiandrosterone (DHEA) sulfate (DHEAS) is observed in premature adrenarche and congenital adrenal hyperplasia. Very high DHEAS levels are typical for adrenal tumors. Approximately 74% of DHEAS is hydrolyzed to DHEA by the steroid sulfatase (STS). The reverse reaction is DHEA sulfation. Besides these two enzyme reactions, the DHEAS transported through the cell membrane is important for its distribution and excretion.

DHEA inhibits leukocyte recruitment through regulation of the integrin antagonist DEL-1

2020-03 Ziogas A, Maekawa T, Wiessner JR, Le TT, Sprott D, Troullinaki M, Neuwirth A, Anastasopoulou V, Grossklaus S, Chung KJ, Sperandio M, Chavakis T, Hajishengallis G, Alexaki VI

Leukocytes are rapidly recruited to sites of inflammation via interactions with the vascular endothelium. The steroid hormone dehydroepiandrosterone (DHEA) exerts anti-inflammatory properties; however, the underlying mechanisms are poorly understood.

2010-05 Jahn MP, Jacob MH, Gomes LF, Duarte R, Araujo AS, Bello-Klein A, Ribeiro MF, Kucharski LC

Dehydroepiandrosterone (DHEA) is an endogenous steroid hormone involved in a number of biological actions. This study shows the effects of DHEA on glucose metabolism, hydrogen peroxide and thioredoxin levels in the skeletal muscle of control and diabetic rats.

Dehydroepiandrosterone inhibits the proliferation and induces the death of HPV-positive and HPV-negative cervical cancer cells through an androgen- and estrogen-receptor independent mechanism

2009-10 Giron RA, Montano LF, Escobar ML, Lopez-Marure R

Dehydroepiandrosterone (DHEA) has a protective role against epithelial-derived carcinomas; however, the mechanisms remain unknown. We determined the effect of DHEA on cell proliferation, the cell cycle and cell death in three cell lines derived from human uterine cervical cancers infected or not with human papilloma virus (HPV).

Dehydroepiandrosterone protects vascular endothelial cells against apoptosis through a Galphai protein-dependent activation of phosphatidylinositol 3-kinase/Akt and regulation of antiapoptotic Bcl-2 expression

2007-07 Liu D, Si H, Reynolds KA, Zhen W, Jia Z, Dillon JS

The adrenal steroid dehydroepiandrosterone (DHEA) may improve vascular function, but the mechanism is unclear. In the present study, we show that DHEA significantly increased cell viability, reduced caspase-3 activity, and protected both bovine and human vascular endothelial cells against serum deprivation-induced apoptosis.
