- The early effects of interferon (IFN) on the pattern of protein synthesis in Swiss 3T3 mouse fibroblasts were investigated by two-dimensional gel electrophoresis of 35S-methionine labeled cell extracts. IFN induced within 4 h the synthesis of three proteins with molecular weights of 48, 49, and 50 kD. An increase in the rate of synthesis of a 31 kD protein was also found. These changes were observed after IFN treatment of exponentially growing cells, density-inhibited cells, serum-starved cells, and serum-stimulated quiescent cells. The same protein patterns were obtained from cells treated with IFN-alpha or IFN-beta. The IFN response was blocked by the addition of actinomycin D, implying de novo transcription of the corresponding species of messenger RNA.
