The human endocrine system is a complex and interlinked series of organs and glands producing hormones critical for normal growth and development, metabolic homeostasis and reproduction. Endocrine-active chemicals that have the ability to disrupt this intricate and well-balanced system, or endocrine disruptors (EDs), are of significant toxicological, and current regulatory, concern.
Current focus is on those compounds that disrupt the Estrogenic, Androgenic, Thyroid and/or Steroidogenesis (EATS) axes. Comprehensive guidance on testing frameworks for endocrine disrupting chemicals acting on these axes have been published by the OECD and by ECHA/EFSA, with the joint ECHA/EFSA guidance also providing strategies for gathering evidence on, and evaluation and interpretation of the endocrine disruption hazard.
Our toxicologists are skilled in the use of high-throughput screening tools, such as the US EPA’s ToxCast, and in the evaluation and interpretation of in silico and in vitro New Approach Methodologies (NAMs) as well as extracting relevant data from existing laboratory animal and epidemiological studies.
