Abstract
In vivo responses to interferon (IFN) in mice were determined by measuring the steady-state levels of induced mRNAs following injection of IFN and poly(I)-poly(C). With cDNA probes for mouse 2'-5' oligoadenylate synthetase (2-5A synthetase) and 1-8, constitutive expression of the corresponding mRNA was detectable in different organs of normal C3H/He mice. These mRNA levels were increased by as much as 15-fold over control levels in various tissues, including the brain, after IFN and poly(I)-poly(C) treatment, coincident with increases in 2-5A synthetase enzyme activity. The basal activity level of this enzyme could be reduced in normal mice by treatment with anti-mouse IFN (alpha + beta) antibody. This treatment also reduced the levels of 2-5A synthetase and 1-8 mRNAs. Thus, physiological levels of circulating IFN maintain elevated levels of IFN-induced mRNAs in mice. Furthermore, changes in 2-5A synthetase enzyme activity reflect the changes in gene expression in vivo.
