Phthalate esters as peroxisome proliferator carcinogens.

Phthalate esters as peroxisome proliferator carcinogens.

The phthalate ester di(2-ethylhexyl) phthalate is both a peroxisome proliferator and a hepatic carcinogen. Peroxisome proliferators as a class are hepatocarcinogenic in rodent species. However, none of the peroxisome proliferators tested to date including the phthalate esters and related alcohol and acid analogs have demonstrated mutagenic or DNA-damaging activity in the in vitro Salmonella typ...

Exposure to phthalate esters.

The American Chemistry Council Phthalate Esters Panel read with great interest the paper by Blount et al. (1) regarding urinary levels of phthalate ester metabolites in a sample set of the Third National Health and Nutrition Examination Survey (NHANES III) population. We have known for some time of this research, and have provided whatever information and assistance we could to the Centers for ...

Peroxisome proliferator-activated receptors: mediators of phthalate ester-induced effects in the male reproductive tract?

Many phthalate ester plasticizers are classified as peroxisome proliferators (PP), a large group of industrial and pharmaceutical chemicals. Like PP, exposure to some phthalates increases hepatocyte peroxisome and cellular proliferation, as well as the incidence of hepatocellular adenomas in mice and rats. Most effects of PP are mediated by three nuclear receptors called peroxisome proliferator...

Di(2-ethylhexyl)phthalate induces hepatic tumorigenesis through a peroxisome proliferator-activated receptor alpha-independent pathway.

Di(2-ethylhexyl)phthalate (DEHP), a commonly used industrial plasticizer, causes liver tumorigenesis presumably via activation of peroxisome proliferator-activated receptor alpha (PPARalpha). The mechanism of DEHP tumorigenesis has not been fully elucidated, and to clarify whether DEHP tumorigenesis is induced via PPARalpha, we compared DEHP-induced tumorigenesis in wild-type and Pparalpha-null...
