Distinct roles of the ERK pathway in modulating apoptosis of Ras-transformed and non-transformed cells induced by anticancer agent FR901228FEBS letters (2005)
AbstractEctopic expression of oncogenic H-Ras in cells results in increases of cell susceptibility to the anticancer agent FR901228. Investigating the roles of Ras-induced pathways in FR901228-induced apoptosis, we have found that the phosphatidylinositol 3-kinase pathway plays an anti-apoptotic role, whereas the stress-activated protein kinase p38 pathway plays a pro-apoptotic role in FR901228-induced apoptosis. Interestingly, the extracellular signal-regulated kinase (ERK) pathway plays an anti-apoptotic role in non-transformed cells; however, it plays a pro-apoptotic role in Ras-transformed cells in response to FR901228 treatment. An essential role of the ERK pathway in regulating caspase-3 contents may contribute to its pro-apoptotic role in Ras-transformed cells.
