The mitogenic effect of Nafenopin, a hypolipidemic hepatic peroxisome proliferator, in mouse liver has been studied in acute and chronically treated mice. After 1, 6 and 32 weeks of treatment, the total hepatic DNA was increased 1.5-2.0-fold over controls. Mitotic and labeling indices were also increased 3-4 fold after 5 days, 6 weeks and 32 weeks of treatment. The increased mitotic activity in nafenopin fed animals was not associated with liver cell necrosis. The nafenopin induced hepatomegaly therefore appears to arise from a combination of cell proliferation, as well as, cellular hypertrophy, which is associated with peroxisome proliferation.
