  • Title: Prostaglandin synthesizing enzyme activities of hepatocytes and non-hepatocytes in rat liver as a function of age.

    Journal: Biochem Int; 1986 Nov; 13(5):827-34. PubMed ID: 3814160.
    Abstract:
    The developmental profile of prostaglandin (PG)-synthesizing enzymes in liver was investigated in rats from the fetus to 2 years old. In the neonatal period, the activities of PGD2-(2.7 nmol/min/mg protein) and PGE2-(2.2 nmol/min/mg protein) synthesizing enzymes were predominant, whereas PGE2-synthesizing enzyme alone further increased in activity during adult to old ages (5.2-6.1 nmol/min/mg protein). In order to determine the sites of PGs production in rat liver, we prepared hepatocytes and non-hepatocytes by a collagenase digestion method. Regardless of the ages we examined, the major PG produced in the hepatocytes was proved to be PGE2, on the other hand, PGD2 was almost exclusively produced in the non-hepatocytes. These results suggest that each PG may have individual roles in the development of rat liver.
