Restriction mapping and the determination of scattered nucleotide sequences have permitted a description of the global structure and evolutionary affinities of the canine herpesvirus (CHV) genome. The global structure closely resembles that of the totally sequenced genomes of varicella-zoster virus and equine herpesvirus 1 (EHV-1) in having a 37 bp inverted(More)
Interferons (IFNs) are pleiotropic cytokines involved in the regulation of physiological and pathological processes. Upon interaction with their specific receptors, IFNs activate the Jak/STAT signalling pathway. Numerous studies suggest, however, that the classical Jak/STAT pathway cannot alone account for the wide range of IFN's biological effects. To(More)
The prolongation of the limited lifespan of human embryonic lung fibroblasts by hydrocortisone was previously associated with increased uridine incorporation into ribosomal RNA (rRNA). Using polyacrylamide gel electrophoresis, we show here that the continuous treatment with 12 microM hydrocortisone results in increased uridine incorporation into rRNA(More)
Rat epithelioid lung cells were transformed with various preparations of SV40 DNA using the Ca2+-precipitation technique. The amount of SV40 genetic information integrated into transformed clones was evaluated by DNA-DNA renaturation kinetics. The growth properties on plastic and in soft-agar were examined, as well as the ability to induce tumors in(More)
