Differential Activation of Nuclear Receptors by Perflunoriated Fatty Acid Analogs and Natural Fatty Acids: A Comparison of Human, Mouse, and Rat Peroxisome Proliferator-Activated Receptor Receptor-a, -b, and -c, Liver X Receptor-b, and Retinoid X Receptor-a

ABSTRACT Administration of ammonium salts of perfluorooctanoate (PFOA) to rats results in peroxisome proliferation and benign liver tumors, events associated with activation of the nuclear receptor (NR) peroxisome proliferator-activated receptor-a (PPARa). Due to its...
