Abstract:
Polyfluoro-alkyl substances (PFAS) are widely distributed environmental contaminants linked to human toxicity and developmental delays, especially low birthweight (LBW). In this study, Human Umbilical Vein Endothelial Cells (HUVECs) were exposed to the PFAS perfluorooctanesulfonic acid (PFOS). After 48-hours, their proliferation, and differential gene expression were assessed. A small, yet significant, reduction in proliferation was seen at 50 μg/mL and 75 μg/mL. RNA sequencing showed that estrogen response and notch signaling pathways were significantly altered. This study increases our understanding of how PFAS may interfere with endothelial cell (HUVECs) functions which may have larger effects on fetal growth, development, and birthweight.
