In the ovary, glucocorticoids are metabolised by 11βHSD enzymes. The bi-directional 11βHSD1 enzyme usually acts as an NADPH-dependent 11-ketoreductase to regenerate cortisol (F) from circulating cortisone (E), while 11βHSD 2 inactivates F using NAD+ as cofactor. Having isolated endogenous inhibitors of 11βHSD1 from porcine follicular fluid (pFF) and ovarian cysts, the aims of this study were to establish whether 11βHSD enzymes interconvert F...
