Protocol

Cell experiment:

Cell lines

Cysticerci; hippocampal

Preparation method

This compound is soluble in DMSO and in ethanol. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

1.7, 3.5, 7 μM for 1-10 days; or 10–100 nM for 6–8 h

Applications

Treatment of T. crassiceps with DHEA decreasd reproduction, motility and viability in a dose- and time-dependent fashion [1]. Moreover, Pre-treatment with DHEA (10–100 nM for 6–8 h) protected hippocampal neurons against excitatory amino acid (0.1, 1, 10, and 50 mM)-induced neurotoxicity in vitro [2].

Animal experiment:

Animal models

Ovarian cortical autograft (‘normograft’) model; or rats model

Dosage form

DHEA single rod implants (length 5 cm, diameter 3.35 mm), subcutaneous administration for 10 weeks.

Applications

DHEA promoted granulosa cell proliferation and increased the follicular anti-Mullerian hormone (AMH) expression at the preantral and early antral follicle stages [3]. Moreover, DHEA protected hippocampal neurons against N-methyl-D-aspartic acid (NMDA)-induced neurotoxicity in vivo [2].

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Dehydroepiandrosterone (DHEA) is an important endogenous steroid hormone [1].

DHEA is an important endogenous steroid hormone and functions as a metabolic intermediate in the biosynthesis of estrogen and androgen. Also, DHEA has a variety of potential biological effects by binding to nuclear and cell surface receptors and acts as a neurosteroid.

In human neural stem cells derived from the fetal cortex, DHEA significantly increased cells growth when grew with leukemia inhibitory factor (LIF) and epidermal growth factor (EGF). Also, DHEA increased neuronal production by 29%. In glial fibrillary acidic protein-positive cells, DHEA significantly increased cells growth, the mRNA and protein of acidic protein [2]. In rat chromaffin cells and pheochromocytoma PC12 cell line, DHEA protected cells against serum deprivation-induced apoptosis with EC50 value of 1.8 nM. DHEA increased the expression of NF-κB and cAMP response element-binding protein, upstream effectors of antiapoptotic Bcl-2 protein. DHEA also activated PKC ɑ/β, a posttranslational activator of Bcl-2 [3].

In male Lister hooded rats, s.c. pellets of DHEA protected hippocampal CA1/2 neurons against N-methyl-D-aspartic acid (NMDA) (5 or 10 nM) [1].
