Mono-(2-Ethylhexyl) Phthalate Promotes Pro-Labor Gene Expression in the Human Placenta
Women exposed to phthalates during pregnancy are at increased risk for delivering preterm, but the mechanism behind this relationship is unknown. Placental corticotropin-releasing hormone (CRH) and cyclooxygenase-2 (COX-2) are key mediators of parturition and are regulated by the non-canonical NF-kB (RelB/p52) signaling pathway. In this study, we demonstrate that one of the major phthalate meta...
متن کاملThe in vitro serum protein-binding characteristics of bis-(2-ethylhexyl) phthalate and its principal metabolite, mono-(2-ethylhexyl) phthalate.
The metabolism and toxicity of the ubiquitous plasticizer, bis-(2-ethylhexyl) phthalate (DEHP), and its principal metabolite, mono-(2-ethylhexyl) phthalate (MEHP), have been extensively investigated. In an attempt to understand their disposition in man, we studied the in vitro serum protein-binding characteristics of these compounds, using ultracentrifugation and agarose gel electrophoresis. Th...
متن کاملRadioimmunoassay for mono-(2-ethylhexyl) phthalate in unextracted plasma.
We report a radioimmunoassay for mono-(2-ethylhexyl) phthalate that has been coupled to a protein carrier as a radioligand. Competitive interference tests with a variety of related compounds indicated the assay to be highly specific. Quantitative comparison of mono-(2-ethylhexyl) phthalate values in plasma and serum samples between the radioimmunoassay and gas chromatographic procedures indicat...
متن کاملFetotoxic effects of mono-2-ethylhexyl phthalate (MEHP) in mice.
Mono(2-ethylhexyl) phthalate (MEHP), one of the main metabolites of di(2-ethylhexyl) phthalate (DEHP), exerted embryo/fetotoxic effects similar to those of DEHP at lower doses. Oral administration of MEHP (1 mL/kg) to the mice of 8 days gestation resulted in less than 32% of live fetuses, all of which were deformed. When DEHP (10 mL/kg) was given to the pregnant mice of 8 days gestation, approx...
متن کاملeffects of mono-(2-ethylhexyl) phthalate and di-(2-ethylhexyl) phthalate administrations on oocyte meiotic maturation, apoptosis and gene quantification in mouse model
objective: phthalates, which are commonly used to render plastics into soft and flexible materials, have also been determined as developmental and reproductive toxicants in human and animals. the purpose of this study was to evaluate the effect of mono-(2- ethylhexyl) phthalate (mehp) and di-(2-ethylhexyl) phthalate (dehp) oral administrations on maturation of mouse oocytes, apoptosis and gene ...
