摘要：

Cytotoxic drugs used in chemotherapy of and cause apoptosis in target . In lymphoid the CD95 (-1/)/() system is a key regulator of apoptosis. Here we describe that doxorbicin induces apoptosis via the CD95/system in T-lines. -induced apoptosis was completely blocked by inhibition of and . Also, doxorbicin strongly stimulates messenger RNA expression in vitro at concentrations relevant for therapy in vivo. CEM and jurkat resistant to CD95-mediated apoptosis were also resistant to doxorbicin-induced apoptosis . Furthermore, doxorbicin-induced apoptosis was inhibited by blocking F(ab')2 anti--1 (anti-CD95) fragments. Expression of mRNA and in vitro was also stimulated by other cytotoxic drugs such as . The finding that apoptosis caused by anticancer drugs may be mediated via the CD95 system provides a new molecular insight into resistance and sensitivity toward chemotherapy in .
