The synthesis of estradiol by the granulosa cells is a prominent event in ovarian physiology and depends on the expression of P450(AROM). FSH induces the expression of P450(AROM) in granulosa cells as a result of the presence in the ovarian promoter of a CRE (cAMP response element)-like sequence (CLS). In rodents, LH downregulates aromatase expression during luteinization by an as yet undescrib...
Prochloraz is a fungicide known to cause endocrine disruption through effects on the hypothalamic-pituitary-gonadal (HPG) axis. To determine the short-term impacts of prochloraz on gene expression and steroid production, adult female fathead minnows (Pimephales promelas) were exposed to the chemical (0 or 300 μg/L) for a time-course of 6, 12 and 24 h. Consistent with inhibition of cytochrome P4...
Cross-sectional studies investigating the relationship between phytoestrogens in diet, urine, or blood with plasma estradiol and sex hormone binding globulin (SHBG) have been inconclusive. We investigated the relationship among phytoestrogen exposure, polymorphisms in the ESR1, COMT, CYP19, and SHBG genes, and plasma estradiol and SHBG levels in 125 free-living postmenopausal women taking part ...
