Dose-related effects of perfluorodecanoic acid on growth, feed intake and hepatic peroxisomal beta-oxidation.

The effects of the persistent peroxisome proliferator, perfluorodecanoic acid (PFDA), on growth, feed intake and the enzyme activities associated with peroxisomal beta-oxidation were studied in female Sprague Dawley rats. Rats received one of six levels of PFDA (0, 0.3, 1.0, 3.0, 10.0 or 30.0 mg/kg/injection) in four IP doses at 2-week intervals. Rats with cumulative doses of less than or equal to 12.0 mg/kg did not differ from control rats in growth or feed intake, while rats receiving cumulative doses of greater than or equal to mg/kg lost weight and decreased their feed intake. Rats which received cumulative doses between these levels increased their feed intake but did not significantly alter their body weight. Total peroxisomal beta-oxidation was decreased in a dose-related manner, whereas the liver to body weight ratio and the activities of individual enzymes comprising the peroxisomal beta-oxidation system, namely fatty acyl-CoA oxidase, enoyl-CoA hydratase, 3-hydroxy-acyl-CoA dehydrogenase, and thiolase, were increased. This study clearly shows that the inhibition of peroxisomal beta-oxidation by PFDA is not reflected in the in vitro measurement of the individual enzyme activities comprising this pathway.[1]
