Improved Determination of Total Serum Estrogenic Bioactivity: Characterisation of Oestrogenic Activity Modulators

Francoise Paris , Marina Grimaldi , Charles Sultan , Patrick Balaguer

Background: Several years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA). In addition to its physiological interest, EBA could be a good marker of endocrine-disrupting compounds (EDCs) with estrogenic activity and thus would be useful in the field of environmental-related endocrine diseases.Aims and objectives: To characterise the type of substances that mediate estrogenic activity.Met...

Confirmation of Exogenous Serum Estrogenic Activity in a Girl with Premature Thelarche

Francoise Paris , Marina Grimaldi , Charles Sultan , Patrick Balaguer

Background: The oestrogenic activity of endocrine-disrupting compounds (EDCs) has been reported to be associated with premature thelarche (PT) and precocious puberty. Some years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA) that is useful in physiology, as well as in the field of the environmental-related endocrine diseases. We recently improved the assay with an evaluation of EBA before and after incubation with estrogen recepto...
