  • Title: Effect of dimethylnitrosamine upon carbamoyl phosphate and ornithine utilization in rat liver.
    Author: Karsai T, Rády P, Nagy Z, Szondy Z.
    Journal: Anticancer Res; 1985; 5(4):441-4. PubMed ID: 2864015.
    Abstract:
    Newborn CFY rats were intraperitoneally treated with a single dose of dimethylnitrosamine. Changes in the activity of carbamoyl-phosphate synthase I and II, ornithine carbamoyltransferase, aspartate carbamoyltransferase and dihydroorotase, i.e. utilization of ornithine and carbamoyl-phosphate pools were followed for 300 days. One or two months after treatment the activity of enzymes which utilize ornithine and carbamoyl-phosphate was enhanced in the cytosol, whereas the activity of the intramitochondrial enzymes in urea synthesis was decreased. Changes in the utilization of ornithine and carbamoyl-phosphate pools, characteristic of proliferating tissues, appeared to be irreversible.
