  • Title: Estrogen metabolism in neural tissues of rabbits: 17 beta - hydroxysteroid oxidoreductase activity.
    Author: Reddy VV.
    Journal: Steroids; 1979 Aug; 34(2):207-15. PubMed ID: 494362.
    Abstract:
    Incubation of adult rabbit neural tissue homogenates with (3H)-estrone and (3H)-estradiol revealed that the conversion of estrone to estradiol is higher in both male and female animals than estradiol to estrone. Both 17 oxidation and reduction are higher in male animals than in females. However, it is observed that the quotient of estrone leads to estradiol/estradiol leads to estrone for pituitary tissue and hypothalamus are higher in females than in males. There is no such dimorphism in cerebral cortex. The overall metabolism in pituitary is higher than in hypothalamus and cortex in both sexes. These results suggest that 17 beta hydroxysteroid oxidoreductase activity may play an important role in the regulation of estrogen function in neuroendocrine tissues.
