There are many kinds of estrogens, and endogenous estrogens produce a variety of estrogen metabolites with similar structure but with different physiological effects after metabolism in vivo. Studies have shown that estrone (E1) widely occurs in the environment and animal-derived

Prolonged sitting and lower levels of physical activity have been associated with increased levels of parent oestrogens (oestrone and oestradiol), the key hormones in female cancers, in postmenopausal women. However, it is unknown whether sitting and physical activity are associated

Higher circulating estradiol levels are generally obtained using conventional radioimmunoassays (RIA) compared to liquid chromatography/tandem mass spectrometry (LC-MS/MS) assays, and this has been attributed to the presence of estradiol metabolites that cross-react with the antibody used in the RIA. This

Despite being widely used to investigate 17β-estradiol (E2)-induced mammary gland (MG) carcinogenesis and prevention thereof, estrogen homeostasis and its significance in the female August Copenhagen Irish (ACI) rat model is unknown. Thus, levels of 12 estrogens including metabolites and conjugates

Background: Prenatal diethylstilbestrol (DES) exposure is associated with adverse reproductive outcomes and cancer of the breast and vagina/cervix in adult women. DES effects on estrogen metabolism have been hypothesized, but reproductive hormone concentrations and metabolic pathways have not been comprehensively
