Peroxisomes in cultured rat hepatocytes have proliferated under treatment with 4-phenylbutyrate. The animal was transgenic for PPARalpha -/-, so phenyl butyrate acts without the PPAR receptor.

Peroxisomes proliferating under treatment with nafenopin over 17 days. Reaction product differs between adjacent organelles giving evidence that their content (catalase) is not freely exchanged, as pr...
