The transcription factor RUNX3, which mediates apoptosis and cell growth inhibition in gastric epithelial cells, is a candidate tumor suppressor that is frequently lost in gastric cancer cells. Here, we found that restoration of RUNX3 expression in the cell line not expressing RUNX3 induced apoptosis and that it physically interacted with the Forkhead(More)
Transforming growth factor-beta (TGF-beta) is implicated as a tumor suppressor because it eliminates cancer cells from normal tissues by inhibiting cell growth and inducing apoptosis. Although p53 tumor suppressor is required for TGF-beta-induced p21 WAF1 expression and cell growth inhibition, its role in TGF-beta-induced apoptosis remains unclear. Here, we(More)
The role of Ras and MAP kinases (MAPKs) in the regulation of erythroid differentiation was studied using a cell line (SKT6) derived from Friend virus (Anemic strain)-induced murine erythroleukemia. This cell line undergoes differentiation in vitro in response to erythropoietin (EPO) or other chemical inducers such as dimethylsulfoxide (DMSO). When a(More)
