To determine whether the angiotensinogen (Ao) gene is expressed in multiple organs of the fetal rat and the changes associated with maturation, fetal (15-20 days of gestation), newborn (1-10 days old), and adult (90 days old) rat tissues were subjected to Northern analysis and hybridization with a full length Ao complementary DNA (cDNA). Whereas Ao messenger RNA (mRNA) was undetectable in fetal livers, Ao sequences were readily detectable 1 h after birth and reached a peak at 24 h of birth. Levels remained elevated at 5 and 10 days after birth to decrease slightly at 90 days of postnatal life. Poly A+ enriched liver RNA was subjected to a similar analysis demonstrating that fetal liver Ao mRNA levels were 50-fold less than the corresponding adult levels. In contrast to the finding in the fetal liver, Ao mRNA was found in fetal brown fat, brains, and kidneys. We conclude that 1) Expression of the Ao gene is developmentally regulated in a tissue-specific manner; 2) Unlike the adult animal, the liver may not be the primary source of Ao in the fetus; 3) Alternate sources of Ao synthesis include fetal brown fat, brain, and kidneys.
