The influence of CTP-OD1-HA and CTP-OD2-HA fusion peptides or combine with imatinib on proliferation of K562 cells

目的研究CTP-OD1-HA和CTP-OD2-HA融合肽及联用imatinib对K562细胞增殖的影响。方法将前期制备的CTP-OD1-HA和CTP-OD2-HA融合肽或连同imatinib作用于K562细胞后,应用细胞增殖及细胞毒性检测试剂盒(MTT)、克隆形成试验方法检测和比较细胞增殖情况。结果 MTT检测发现,CTP-OD1-HA和CTP-OD2-HA融合肽能够抑制K562细胞增殖,联用imatinib后,效果更加明显;克隆形成试验结果显示,CTP-OD1-HA和CTP-OD2-HA可抑制K562细胞株的克隆形成能力。结论 CTP-OD1-HA和CTP-OD2-HA融合肽可以特异性抑制K562细胞的增殖,并增加imatinib的敏感性。

Objective To study the influence of CTP-OD1-HA and CTP-OD2-HA fusion peptides and combined with imatinib on proliferation of K562 cells.Methods K562 cells were treated with CTP-OD1-HA and CTP-OD2-HA peptides or together with imatinib.The proliferation of cells were detected and compared by MTT and clone formation methods.Results MTT examination demonstrated that CTP-OD1-HA and CTP-OD2-HA peptides could inhibit the proliferation of K562 cells,and the effect was more obvious when acted along with imatinib;Clone formation showed that CTP-OD1-HA and CTP-OD2-HA peptides suppressed the continuous colony forming ability of K562 cells.Conclusion CTP-OD1-HA and CTP-OD2-HA could specially inhibit the proliferation of K562 cells,and increase the sensitivity of imatinib.
