The potential inhibition of the growth of cisplatin-resistant ovarian cancer cell line COC1/DDP by ethylenediamine-di-(ethacrynic amide)(EDEA) was investigated.Cell viability was checkedby CCK- 8 assay,apoptosis rate of cells was detected with flow cytometry;expression of Bcl- 2 family proteins was detected with western blotting;morphology of COC1/DDP cells was observed after Wright staining.EDEA showed low toxicity to normal cells with the maximum level of about 1.2 μmol/L on both HEK293 and LO2 cells;DDP ...
恶性肿瘤目前还无法攻克而发生率逐渐攀升。例如,在女性生殖系统的妇科肿瘤中,卵巢癌发病率为第三位,但死亡率居第一位,5年生存率仅有20%~30%(H akom ori and Igarashi,1 995)。顺铂是卵巢癌化疗一线药物,但由于肿瘤对顺铂耐药,导致化疗效果不佳,从而降低患者五年生存率(K urze
