摘要: Leukemia is a major type of cancer affecting significant segment the population, and especially children. In fact, leukemia most frequent childhood cancer, with 26 % all cases, 20 mortality. The multidrug resistance phenotype (MDR) considered one causes failure in chemotherapy. present study aimed to investigate relationship between expression MDR1 CYP450 genes human chronic myelogenous cells (K-562) treated cisplatin (cisPt) two ruthenium-based coordinated complexes [cisCRu(III) cisDRu(III)]. tested compounds induced apoptosis K-562 tumor as evidenced by caspase 3 activation. Results also revealed that amplification P-gp gene greater exposed cisPt cisCRu(III) than cisDRu(III). Taken together, these results strongly demonstrate MDR-1 overexpression could be associated MDR phenotype, moreover, it contributing platinum structurally related compound, cells.
