1 DHEA and DHEA sulfate differentially regulate neural androgen receptor and its transcriptional activity. Dehydroepiandrosterone androgen receptor Mus musculus
2 Semi-quantitative Western blot analysis showed that DHEA treatment significantly augmented AR in mouse brain and GT1-7 cells in a dose-dependent manner and that these effects were not blocked by trilostane (TRIL), a known 3beta-hydroxysteroid dehydrogenase inhibitor. Dehydroepiandrosterone androgen receptor Mus musculus
3 DHEA also promoted AR-mediated reporter gene expression as a function of dose and the effect was comparable with or without the addition of TRIL. Dehydroepiandrosterone androgen receptor Mus musculus
4 In contrast, DHEA-S treatment failed to increase AR level in the mouse brain or GT1-7 cells and modestly induced AR-mediated reporter gene expression only at substantially elevated concentrations compared to DHEA. Dehydroepiandrosterone androgen receptor Mus musculus
5 In contrast, DHEA-S treatment failed to increase AR level in the mouse brain or GT1-7 cells and modestly induced AR-mediated reporter gene expression only at substantially elevated concentrations compared to DHEA. Dehydroepiandrosterone androgen receptor Mus musculus
6 The findings demonstrate that DHEA is capable of exerting androgenic effects through AR while the androgenicity of DHEA-S is negligible. Dehydroepiandrosterone androgen receptor Mus musculus
