Tumor necrosis factor-alpha (TNF) is well known for its cytotoxic effect on malignant cells. Its role in cell cycle control is relatively less known. In this study, we found that TNF induced G(1) arrest of TF-1 and MV4-11 cells while simultaneously causing apoptosis. Treatment of the cells with TNF for 48 h caused cell cycle arrest, accompanied by(More)
How mitogens reduce the abundance of the cell cycle inhibitor p27(Kip1) is an important question, and regulation of p27(Kip1) translation and turnover has been described. Here we show that platelet-derived growth factor (PDGF) reduces the activity of the p27(Kip1) promoter and the abundance of the p27(Kip1) transcript in density-arrested mouse fibroblasts.(More)

Transforming Growth Factor-beta (TGFbeta) is known to be a negative regulator of G1 cyclin/cdk activity. It is not clear whether TGFbeta has any effect on G2 checkpoint kinases. We have found that TGFbeta downregulated the expression of several G2 checkpoint kinases including cdc2, cyclin B1, and cdc25c without causing cell accumulation in G2/M phases in(More)
