Equilin-3-sulfate and delta8,9-dehydroestrone-3-sulfate are two isomers found in equine conjugated estrogens that differ in structure only by the position of a double bond in the steroid B-ring. These geometric isomers were not resolved on a C18 column during the analysis

There is growing concern of exposure of fish, wildlife and humans to water sources contaminated with oestrogens and the potential impact on reproductive health. Environmental oestrogens can come from various sources including concentrated animal feedlot operations (CAFO), municipal waste, agricultural

Identification of biomarkers potentially provides prognostic information that can help guide clinical decision-making. Given the relationship between estrogen exposure and endometrial cancer, especially low grade endometrioid carcinoma, we hypothesized that high expression of genes induced by estrogen would identify low
