Mono-(2-ethylhexyl) Phthalate Increases Oxidative Stress Responsive miRNAs in First Trimester Placental Cell Line HTR8/SVneo. Academic Article uri icon


  • Phthalates, an endocrine disruptor group, cause oxidative stress (OS) in the placenta. However, no studies have reported OS-related miRNAs induced by phthalates. In the present study, we demonstrate that mono-(2-ethylhexyl) phthalate (MEHP) induces OS responsive miR-17-5p, miR-155-5p, and miR-126-3p in HTR8/SVneo in a dose- and time-dependent manner. Furthermore, MEHP altered the expression of phosphoinositide-3-kinase regulatory subunit 1, phosphatase and tensin homolog, CDKN2A interacting protein, superoxide dismutase 2, and 3-hydroxysterol-D24 reductase, which are involved in OS and predicted to be regulated by these miRNAs. Our results suggest that placental exposure to MEHP may result in aberrant miRNA expression leading to pregnancy complications.
