The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction (CERHR) conducted an updated evaluation of the potential for DEHP to cause adverse effects on reproduction and development in humans. The first CERHR expert panel evaluation of DEHP was completed in 2000 by the Phthalates Expert Panel. CERHR selected DEHP for an updated evaluation because of: (1) wide...

OBJECTIVE We previously demonstrated that among 54 infants in neonatal intensive care units, exposure to polyvinyl chloride plastic medical devices containing the plasticizer di(2-ethylhexyl) phthalate (DEHP) is associated with urinary concentrations of mono(2-ethylhexyl) phthalate (MEHP) , a DEHP metabolite. In this follow-up report, we studied the neonates' exposure to DEHP-containing devices...

Plastic products are wildly used in human life. Di(2-ethylhexyl)phthalate (DEHP) is an essential additive in plastic manufacturing and is used as plasticizer for many products including plastic food packaging. DEHP is a teratogenic compound and can cause potent reproductive toxicity. DEHP can also cause liver damage, peroxisome proliferation, and carcinogenesis. DEHP is also strongly associated...

The peroxisome proliferator-activated reccptora (PPARa) is the mediator of the biological effects of pcroxisome proliferators through control of gene transcription. To determine if the toxic effects of di(2-ethylhexy1)phthalate (DEHP) are mediated by PPARa, we examined its effect in PPARa-null micc. Male Sv1129 mice. PPARa-null (-/-) or wild-typc (+I+) were fed nd libirirrn either a control die...

Red cell concentrates (RCC) are stored for 35 to 42 days in plastic containers manufactured with the liquid plasticizer di(2-ethylhexyl)phthalate (DEHP). DEHP leaches from the polyvinylchloride (PVC) plastic bag, then binds to and stabilizes the RC membrane. This study was undertaken to determine the deformability of the RC membrane using an osmotic gradient ektacytometer and to relate these me...

Di-(2-ethylhexyl) phthalate (DEHP) has been widely used in polyvinyl chloride products and has become ubiquitous in the developed countries. DEHP reportedly displays an adjuvant effect on immunoglobulin production. However, it has not been elucidated whether DEHP is associated with the aggravation of atopic dermatitis. We investigated the effects of DEHP on atopic dermatitis-like skin lesions i...

Diethylhexyl phthalate (DEHP) is suspected to be an inevitable factor related to metabolic disease. Our previous study demonstrated that excess DEHP could exacerbate non-alcoholic fatty liver disease (NAFLD) in SD rats. Addressing the terra incognita in DEHP-induced metabolic dysfunction, this study used HepG2 cells to investigate the potential mechanisms involved in DEHP-induced toxicity in vi...

Di(2-ethylhexyl)phthalate (DEHP) is a widely used plasticizer and a potentially nongenotoxic carcinogen. Its mechanism had been earlier proposed based on peroxisome proliferator-activated receptor alpha (PPARalpha) because metabolites of DEHP are agonists. However, recent evidence also suggests the involvement of non-PPARalpha multiple pathway in DEHP-induced carcinogenesis. Since there are dif...

Safety concerns about di-(2-ethylhexyl)phthalate (DEHP), a plasticizer and a probable endocrine disruptor, have attracted considerable public attention, but there are few studies about long-term exposure to DEHP. DEHP toxicity is thought to involve peroxisome proliferator-activated receptor alpha (PPARalpha), but this contention remains controversial. For investigation of the long-term toxicity...

Di-(2-ethylhexyl) phthalate (DEHP) is an endocrine disrupting chemical commonly used as a plasticizer in medical equipment, food packaging, flooring, and children's toys. DEHP exposure during early development has been associated with adverse neurobehavioral outcomes in children. In animal models, early exposure to DEHP results in abnormal development of the reproductive system as well as alter...
