The Relationship Between Maternal Exposure to Endocrine-Disrupting Chemicals and the Incidence of Congenital Heart Diseases: A Systematic Review and Meta-Analysis
Science
16 Dec 2024 | Metabolites
PFAS can disrupt the endocrine system by binding to nuclear hormone receptors such as estrogen and androgen receptors, potentially interfering with hormone signaling pathways that regulate reproductive, metabolic, and developmental processes. Here, a model was developed to predict how strongly different PFAS bind to these receptors.
