Randomized trial investigates dsRNA-dependent phosphorylation in fibroblasts, suggesting growth-related regulation.

The aim is to explore the relationship between cell growth and the phosphorylation of a specific dsRNA-dependent kinase in 3T3 fibroblasts.
Cultured mouse 3T3-F442A and 3T3-C2 fibroblasts were used for experimentation.
Phosphorylation levels of the 67K protein were analyzed under varying growth conditions.
Interferon treatment was applied to assess its effect on phosphorylation.
Low levels of dsRNA-dependent phosphorylation of the 67K protein were detectable in low-density cells.
Phosphorylation of the 67K protein and the 38K eIF-2 alpha occurred simultaneously but decreased in confluent cells.
Interferon treatment increased dsI phosphorylation at all growth stages.

Petryshyn et al. (1984) studied this question.
