Title

Gut-microbiome-expressed 3beta-hydroxysteroid dehydrogenase degrades estradiol and is linked to depression in premenopausal females

Overall design

The aim of this study was to determine whether heterologous expression of 3beta-hydroxysteroid dehydrogenase in E. coli can induce depression-like behaviors in female mice. The 3beta-hydroxysteroid dehydrogenase gene TS2020_3397 was introduced into E. coli to obtain the E. coli-pTS07, and the vector pET28a was introduced into E. coli to construct E. coli-pet28a as the control. C57BL/6J mice were divided into the following 3 groups: (1) ovariectomy + estradiol group (ovariectomy followed by gavage estradiol for 6 weeks), (2) ovariectomy + estradiol + pTS07 group (ovariectomy followed by gavage estradiol for 6 weeks and E. coli-pTS07 for 4 weeks), and (3) ovariectomy + estradiol + pET28a group (ovariectomy followed by gavage estradiol for 6 weeks and E. coli-pET28a for 4 weeks). Liquid chromatography-tandem mass spectrometry was used to compare serum estradiol levels between groups (n = 6/group).
