Abstract

We report that anticancer 5-fluoro-2'-deoxyuridine (FUdR) shows cytotoxicity against mouse cancer cell line FM3A cells, using a progeny clone F28-7 and its variant F28-7-A. In this process, the cell-death morphology is different between F28-7 and F28-7-A cells, that is, necrosis in F28-7 but apoptosis in F28-7-A cells. Recently we have investigated the gene and protein expression profiles of necrosis and apoptosis induced by FUdR using transcriptomic and proteomic analysis. In the proteomic analysis of these cells before their exposure to FUdR, the nuclear inner-membrane protein lamin B1 is up-regulated in F28-7 but not in F28-7-A, suggesting that lamin B1 may possess a function to regulate the morphology of cell-death. A knockdown of lamin B1 expression in F28-7 cells has now been performed by use of the small interfering RNA technique, resulting in a decrease of the lamin B1-expression level down to the level in F28-7-A. Remarkably, the FUdR-induced death morphology of this knocked-down F28-7 was apoptosis, definitely different from the necrosis that occurs in the FudR-treated original F28-7. This finding suggests a new role for lamin B1 as a regulator in the cell death.
