Medical Studies on DHEA –The Latest Facts
Are you looking for a quick overview of the latest research on DHEA and its multiple applications? In this section, you will find the most important recent studies listed individually. Of course, you will also find these studies listed in their respective subject categories.
The presented selection of studies was curated by the scientific committee of Interchron, the international forum for chronobiology, and by ea³m, the European Academy of Preventive and Anti Aging Medicine, and will be continuously updated.
Medical Studies on DHEA –The Latest Facts
Circadian rhythms of 11-oxygenated C19 steroids and ∆5-steroid sulfates in healthy men
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.
The effects of puberty and its hormones on subcortical brain development
Puberty triggers a period of structural “re-organization” in the brain, when rising hormone levels act via receptors to influence morphology. However, our understanding of these neuroendocrine processes in humans remains poor.
Selected by Bioinformatics and Molecular Docking Analysis, Dhea and 2-14,15-Eg are Effective Against Cholangiocarcinoma
To identify novel targets for the diagnosis, treatment and prognosis of cholangiocarcinoma, we screen ideal lead compounds and preclinical drug candidates with MYC inhibitory effect from the ZINC database, and verify the therapeutic effect of Dhea and 2-14,15-Eg on cholangiocarcinoma.
Dehydroepiandrosterone Shifts Energy Metabolism to Increase Mitochondrial Biogenesis in Female Fertility with Advancing Age
Female reproductive aging is an irreversible process associated with a decrease in oocyte quality, which is a limiting factor for fertility.
In vitro and in vivo tenocyte-protective effectiveness of dehydroepiandrosterone against high glucose-induced oxidative stress
Dehydroepiandrosterone (DHEA), an adrenal steroid, has a protective role against diabetes. This study aimed to investigate the in vitro and in vivo protective effects of DHEA against high glucose-induced oxidative stress in tenocytes and tendons.
DHEA-pretreatment attenuates oxidative stress in kidney-cortex and liver of diabetic rabbits and delays development of the disease
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
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.
Correction to: Dehydroepiandrosterone Sulphate (DHEAS) concentrations stringently regulate fertilization, embryo development and IVF outcomes: are we looking at a potentially compelling ‘oocyte-related factor’ in oocyte activation?
Erratic oocyte-activation affects fertilization and embryo development. Dehydro-epiandrosterone sulphate (DHEAS) is present in theca/cumulus-granulosa cells, regulates the same calcium-pumps that cause calcium-oscillations in mice and its levels are altered in women with no or low fertilization rates. Yet no study has explored correlation of DHEAS with oocyte-activation.
The therapeutic effect of dehydroepiandrosterone (DHEA) on vulvovaginal atrophy
Vulvovaginal atrophy (VVA) is a chronic disease that mostly occurs in postmenopausal women. After menopause, insufficient sex hormones affect the anatomy of the vagina and cause drastic physiological changes.
The use of saliva steroids (cortisol and DHEA-s) as biomarkers of changing stress levels in people with dementia and their caregivers: a pilot study
The rationale was to explore the efficacy/sensitivity of using morning and evening cortisol levels as biomarkers for stress reduction in persons with dementia (PWDs) and their family caregivers (FCGs) participating in a music intervention program.
