N2 - Induced interferon-beta (IFN-beta) mRNA was localized in human FS-4 fibroblasts by in situ hybridization using biotinylated probes. The hybridization sites were detected by incubation with a nick-translated genomic DNA probe (1.8 kb) via streptavidin-colloidal gold followed by silver contrast enhancement. The positive signals were observed by reflection-contrast light microscopy. IFN-beta mRNA was transiently induced by poly r(I): r(C) in fibroblasts 2-4 h after induction. Induction in the presence of cycloheximide and actinomycin D (superinduction conditions) exhibited an enhanced level of IFN-beta mRNA with a maximum at 4-8 h. The kinetics of the IFN-beta mRNA expression in the cytoplasm as revealed by in situ hybridization proved to be compatible with the results of Northern blotting experiments of total cellular RNA.
