产品介绍
Dehydroepiandrosterone (DHEA) and its sulfate ester, DHEAS, together represent the most abundant steroid hormones in the human body .

Cell lines

HCC1 cell line

Preparation Method

Transferred cells to serum-free dehydroepiandrosterone (DHEA) containing either 0.1% ethanol which was added to all control cultures or 10-12-10-6 M DHEA. The cell culture supernatant was harvested after 72 h.

Reaction Conditions

10-12-10-6 M for 72 hours

Applications

Co-treatment with DEX (10-7 M)/ANDI (10-7 M) or DEX (10-7 M)/DHEA (10-7 M) reversed the increase in RANKL mRNA expression

Animal models

female BALB/c mice

Preparation Method

Effects of treatment with dehydroepiandrosterone (DHEA) were assessed on either ovaries with functional corpora lutea (CL) or regressing CL by two s.c. injections of 60 mg DHEA/kg body weight (DHEA group), 24 h apart on days 3 and 4 after ovulation, followed by decapitation on day 5 (functional CL) or on day 7 and 8, followed by decapitation on day 9 (regressing CL).

Dosage form

s.c., 60 mg/kg

Applications

In mice with functional CL (day 5), the hyperandrogenization with dehydroepiandrosterone (DHEA) decreased both serum P and estradiol (E2) levels when compared to controls

产品描述

Dehydroepiandrosterone (DHEA) and its sulfate ester, DHEAS, together represent the most abundant steroid hormones in the human body[1].

Dehydroepiandrosterone (DHEA) (10-8 and 10-6 M) or DHEAS pretreated rat cerebral cortical cultures was increased neuronal survival when the cultures subjected to anoxia for 2 h[2]. When rat cerebral cortical cultures were subjected to anoxia for 2 h in an anaerobic chamber and pretreated with dehydroepiandrosterone (DHEA) (10-8 and 10-6 M) or DHEAS (10-6 M), there was increased neuronal survival. Using cultured neural precursors from rat embryonic forebrains, dehydroepiandrosterone (DHEA) (50 and 100 nM) activated the serine-threonine protein kinase Akt, which is widely implicated in cell survival signaling[3].

Dehydroepiandrosterone (DHEA) treating had better locomotor recovery on CD-1 female mice, after contusive spinal cord injury (SCI), and also left-right coordination, and fine motor control than control animals[4]. Mice treated with dehydroepiandrosterone (DHEA) also had significantly more white matter spared at the epicenter of the injury and reduced area of reactive gliosis surrounding the lesion. Dehydroepiandrosterone (DHEA) treatment was intensive and consisted of three different modes of administration: a DHEA Matrigel patch (10-10 M) applied to the spinal cord before closure of the wound, followed by 12 days of i.p. injections of saline containing Dehydroepiandrosterone (DHEA) (10-6 M or 0.02 mg/kg/day) after SCI, and Dehydroepiandrosterone (DHEA) (10-6 M) in the drinking water for 42 days[4].
