摘要: Abstract The development of acquired resistance to antineoplastic drugs and the associated broad cross-resistance other agents frequently limits effectiveness chemotherapy. Ling coworkers have demonstrated that Chinese hamster ovary (CHO) cells develop phenotype pleiotropic drug which is manifest by a decrease in accumulation these hence cytotoxicity (1). role membrane glycoproteins expression primary human tumors an area active investigation (2–4). We developed series ovarian cancer cell lines with melphalan, cisplatin, or adriamycin (5). These exhibit sensitivity/resistance profiles characteristic resistance. In addition, melphalan cisplatin resistant variants are also cross-resistant irradiation (6). Both can be reversed lowering glutathione (GSH) levels buthionine sulfoximine (BSO) (6,7). present study, GSH sensitivity than was examined BSO-mediated depletion GSH. patterns both were compared following lines.
