The mode of cell death induced by 1 microM 5-fluoro-2'-deoxyuridine (FdUrd) changed in a wild-type F28-7 clone of mouse mammary tumor FM3A cells after a six-month culture. In the original stocked F28-7 clone, FdUrd-induced cell death was accompanied by necrosis-like cell swelling and DNA fragmentation to 100-200 kbp. In subclone F28-7-A isolated from F28-7 cells, which had been cultured for six months, apoptotic bodies and nucleosomal DNA-ladder fragments were observed with the treatment. Furthermore, we investigated the differences in FdUrd-induced intracellular signals between these clones. In F28-7 cells, FdUrd induced increases in caspase-3-like activity, and the mRNA levels of the c-jun, c-fos and c-myc genes, which were greater and earlier than those in F28-7-A cells. Moreover, intracellular acidification occurred in F28-7-A cells treated with FdUrd, though it was not observed in F28-7 cells. These findings suggest that FdUrd-induced cell death occurred through the death program to cell lysis (necrosis) without apoptosis when the induction of these intracellular signals was very high and when intracellular acidification was deficient. Investigation of the differences in the mode of FdUrd-induced cell death between these clones would be important for elucidating the molecular mechanism of pivotal events guiding cells toward either apoptosis or necrosis.
