Reproductive DHEA-S
Reproductive DHEA-S Analyte Information - 1 - DHEA-S Introduction DHEA-S, DHEA sulfate or dehydroepiandrosterone sulfate, it is a metabolite of dehydroepiandrosterone (DHEA) resulting from the addition of a sulfate group. It is the sulfate form of aromatic C19 steroid with 10,13-dimethyl, 3-hydroxy group and 17-ketone. Its chemical name is 3β-hydroxy-5-androsten-17-one sulfate, its summary formula is C19H28O5S and its molecular weight (Mr) is 368.5 Da. The structural formula of DHEA-S is shown in (Fig.1). Fig.1: Structural formula of DHEA-S Other names used for DHEA-S include: Dehydroisoandrosterone sulfate, (3beta)-3- (sulfooxy), androst-5-en-17-one, 3beta-hydroxy-androst-5-en-17-one hydrogen sulfate, Prasterone sulfate and so on. As DHEA-S is very closely connected with DHEA, both hormones are mentioned together in the following text. Biosynthesis DHEA-S is the major C19 steroid and is a precursor in testosterone and estrogen biosynthesis. DHEA-S originates almost exclusively in the zona reticularis of the adrenal cortex (Fig.2). Some may be produced by the testes, none is produced by the ovaries. The adrenal gland is the sole source of this steroid in women, whereas in men the testes secrete 5% of DHEA-S and 10 – 20% of DHEA. The production of DHEA-S and DHEA is regulated by adrenocorticotropin (ACTH). Corticotropin-releasing hormone (CRH) and, to a lesser extent, arginine vasopressin (AVP) stimulate the release of adrenocorticotropin (ACTH) from the anterior pituitary gland (Fig.3). In turn, ACTH stimulates the adrenal cortex to secrete DHEA and DHEA-S, in addition to cortisol. -
Pizotifen Activates ERK and Provides Neuroprotection in Vitro and in Vivo in Models of Huntington’S Disease
Journal of Huntington’s Disease 1 (2012) 195–210 195 DOI 10.3233/JHD-120033 IOS Press Research Report Pizotifen Activates ERK and Provides Neuroprotection in vitro and in vivo in Models of Huntington’s Disease Melissa R. Sarantos1, Theodora Papanikolaou1, Lisa M. Ellerby∗ and Robert E. Hughes∗ The Buck Institute for Research on Aging, Novato, CA, USA Abstract. Background: Huntington’s disease (HD) is a dominantly inherited neurodegenerative condition characterized by dysfunction in striatal and cortical neurons. There are currently no approved drugs known to slow the progression of HD. Objective: To facilitate the development of therapies for HD, we identified approved drugs that can ameliorate mutant huntingtin- induced toxicity in experimental models of HD. Methods: A chemical screen was performed in a mouse HdhQ111/Q111 striatal cell model of HD. This screen identified a set of structurally related approved drugs (pizotifen, cyproheptadine, and loxapine) that rescued cell death in this model. Pizotifen was subsequently evaluated in the R6/2 HD mouse model. Results: We found that in striatal HdhQ111/Q111 cells, pizotifen treatment caused transient ERK activation and inhibition of ERK activation prevented rescue of cell death in this model. In the R6/2 HD mouse model, treatment with pizotifen activated ERK in the striatum, reduced neurodegeneration and significantly enhanced motor performance. Conclusions: These results suggest that pizotifen and related approved drugs may provide a basis for developing disease modifying therapeutic interventions for HD.
