Antiepileptic drugs are endocrine disruptors for the human fetal testis ex vivo.

Valproic acid (VPA) has long been the most widely used antiepileptic drug (AED) for the treatment of epilepsy, bipolar psychiatric disorders, and migraine. However, long-term VPA treatment has several adverse effects on the male reproductive system notably on endocrine functions and/or spermatic parameters. In utero exposure of the fetus to VPA is well known to be associated with a higher risk of several congenital malformations including those of male reproductive organs.

Transcriptional profiling of the developing rat ovary following intrauterine exposure to the endocrine disruptors diethylstilbestrol and ketoconazole.

Exposure to endocrine-disrupting chemicals (EDCs) during development may cause reproductive disorders in women. Although female reproductive endpoints are assessed in rodent toxicity studies, a concern is that typical endpoints are not sensitive enough to detect chemicals of concern to human health. If so, measured endpoints must be improved or new biomarkers of effects included.

PFOS disrupts key developmental pathways during hiPSC-derived cardiomyocyte differentiation in vitro.

Exposure to perfluorooctanesulfonic acid (PFOS) has been associated with congenital heart disease (CHD) and decreased birth weight. PFOS exposure can disrupt signaling pathways relevant for cardiac development in stem cell-derived cardiomyocyte assays, such as the PluriBeat assay, where spheroids of human induced pluripotent stem cells (hiPSCs) differentiate into contracting cardiomyocytes. Notably, cell line origin can also affect how the assay responds to chemical exposure.

PFOS-induced thyroid hormone system disrupted rats display organ-specific changes in their transcriptomes.

Perfluorooctanesulfonic acid (PFOS) is a persistent anthropogenic chemical that can affect the thyroid hormone system in humans and animals. In adults, thyroid hormones (THs) are regulated by the hypothalamic-pituitary-thyroid (HPT) axis, but also by organs such as the liver and potentially the gut microbiota. PFOS and other xenobiotics can therefore disrupt the TH system at various locations and through different mechanisms.
