中文摘要:
      目的探讨MicroRNA-98(miR-98)对肺腺癌耐顺铂细胞系A549/DDP顺铂耐药性的影响。方法利用MicroRNA(miRNA)芯片及生物信息学筛选出miR-98。将miR-98质粒载体瞬时转染至A549/DDP细胞;MTT检测细胞药物敏感性的改变。结果在A549/DDP细胞中miR-98表达水平下调。转染miR-98的A549/DDP细胞生长抑制率明显增高。结论miR-98能够增加肺腺癌耐药细胞株A549/DDP对顺铂的药物敏感性。
英文摘要:
      ObjectiveThis study investigated the effect of microRNA-98 on cisplatin resistance in cisplatin-resistant human lung adenocarcinoma cell line A549/DDP.MethodMicroRNA-98 was selected using MicroRNA microarray and bioinformatics.Pre-miR-98(TM) (miR-98) was transient transfected into A549/DDP cells.Drug sensitivity of the cells to cisplatin (DDP) was analyzed with MTT.ResultThe expression of MicroRNA-98 was marked downregulation in the A549/DDP compared to parental A549 cells.MTT results showed that miR-98 transfectants had a higher cell inhibition rate than A549/DDP cells or negative.ConclusionMicroRNA-98 increased cell spontaneous sensitized 549/DDP cells to DDP.
