Carbon tetrachloride (CCl4) poisoning affects glycoprotein processing and maturation at the level of rat liver microsomes and Golgi apparatus. HPLC analysis showed that within 5-60 min after CCl4 administration the levels of total dolichol, free dolichol and dolichyl-phosphate strongly decreased both in total microsomes and in Golgi apparatus. The most marked and early reduction of total dolichol was observed in the secretory membranes of Golgi area already 15 min after CCl4 poisoning. The incubation of CCl4-pretreated isolated hepatocytes with [3H]-mevalonate showed a significant slowing down of the label incorporation into both free-dolichol and dolichyl-phosphate. Moreover, lipid peroxidation might cause alterations in the molecular structure of both free-dolichol and dolichyl-phosphate. A notable prevention of dolichol decrease was observed in animals pretreated with vitamin E. The results suggest that the prooxidant activity of CCl4 is able to affect the metabolism of dolichol either by increasing the oxidative degradation or impairing the biosynthetic pathway.
