We studied the impact of tumorigenic poxviral infection on key regulators of cell cycle progression. Malignant fibroma virus (MV) is a virulent poxvirus that causes severe immunological impairment in vivo and in vitro. It also directs expression of important cellular regulatory proteins, such as p53. Its avirulent relative, Shope fibroma virus (SFV), has little effect on the immune system or p53. Accordingly we examined the effects of MV and SFV on the cell cycle in RK-13 rabbit kidney fibroblasts. MV caused an accumulation of cells in G2/M phase and decreased the percentage of cells in G0/G1. Prolongation of G2/M phase was associated with increased levels of cyclin B protein, decreases in cyclin A and cdc2 proteins, and diminished cdc2 activity. In contrast SFV did not affect cellular cycling detectably. SFV infection was accompanied by large increases in cyclin A and cdc2 proteins and increased cdc2 activity. Thus alterations in cell cycle transit during virus infection may reflect active direction in which virus induces changes in cell cycle regulators. Such changes may be important in the differences in virulence between MV and SFV.
