title: The expression of liver acute-phase protein genes during rat development and in response to inflammation of the dam.
abstract: The hepatic expression of albumin (Al) and plasma acute phase protein genes (APP) was examined during the development of rat liver and in response to inflammation of the dam. Throughout the 10- to 20-day gestation period the level of alpha 2-macroglobulin (alpha 2M) mRNA in fetal liver exceeded twice that of the adult liver. The concentrations of the other APP and Al mRNAs were 10-30% of those of the adult liver between days 10 and 13 of gestation, then increased to values which ranged from 40% for haptoglobin (Hp) to 80% for Al and alpha 1-acid glycoprotein (AGP) mRNAs on day 19 of gestation. The transition of fetuses to an extrauterine environment was followed by a temporary overexpression of the Hp gene and an increase of the fibrinogen (Fb), AGP and thiostatin (TST) mRNAs to adult levels. Fetal liver responded to inflammation of the mother by a transcriptional induction of all of the investigated APP genes, except for the Fb gene whose level of expression remained unchanged. The pattern of individual APP genes expression in maternal and fetal livers was similar and characteristic for the acute phase reaction.
