“…497, 515), 7-keto-and 7-hydroxy-pregnenolone (515), and 5␣-androstane-3␤-ol-7,17-dione and 5␣-androstane-3␤-ol-7-hydroxy,17-one (515). Additionally, 11␤-HSD1 may act as an epimerase, interconverting 7␣-and 7␤-hydroxy-steroids via a 7-keto intermediate (277,278,497). Epimerase activity requires oxidative and reductive activities and therefore may be determined by H6PDH levels and glucose availability (515).…”

“…La 11β-HSD1, uniquement exprimée dans le réticulum endoplasmique des tissus sensibles aux glucocorticoïdes et produite en faible quantité (Jacolot et al, 1981), est responsable de l'interconversion 7α/7β (Chalbot et Morfin, 2005 ;Hennebert et al, 2007, Muller et al, 2006b). Ces métabolites 7-hydroxylés, uniquement synthétisés au niveau de tissus cibles, sont détectables dans le sang de femmes et d'hommes sains et leur quantité est âge-et sexedépendant (Hill et al, 2005).…”

“…Une action anti-oxydante de la 7α-hydroxy-DHEA dans l'intestin (Pélissier et al, 2004(Pélissier et al, et 2006 ainsi qu'un rôle dans le contrôle de la concentration de glucorticoïdes via son interaction avec la 11β-HSD1 (Muller et al, 2006b ;Hennebert et al, 2007) ont été mis en évidence. De plus, ce stéroïde également produit au niveau de l'hippocampe par le CYP7B1 pourrait jouer un rôle dans la maladie d'Alzheimer.…”

“…Epiandrosterone (EpiA), which is derived from DHEA, is also converted into 7-hydroxylated metabolites (Kim et al, 2004). We have recently shown that 11-HSD1 is responsible for converting 7-hydroxy-EpiA into 7-hydroxy-EpiA (Chalbot & Morfin, 2005;Hennebert et al, 2007b), which is readily produced in small quantities in human tissues (Jacolot et al, 1981;Kim et al, 2004). 7β-Hydroxy-EpiA has been shown to exert neuroprotective effects in vivo at remarkably low doses in animal models of cerebral ischemia (Pringle et al, 2003) and Alzheimer's disease (Dudas et al, 2004).…”
