新型多聚体微泡携带舒尼替尼抑制人肾癌GRC-1细胞生长及促凋亡的实验研究

摘要

目的 观察新型多聚体微泡携带舒尼替尼对人肾癌GRC-1细胞生长及凋亡的影响.方法 将体外培养的人肾癌GRC-1细胞随机分为6组:空白对照组、单纯微泡组、单纯脂质体组、舒尼替尼组、新型多聚体微泡载舒尼替尼不联合超声组、新型多聚体微泡载舒尼替尼联合超声组.MTT法观察不同处理组细胞生存率,Sigma-FITC荧光染色及透射电镜检测细胞凋亡.结果 新型多聚体微泡载舒尼替尼联合超声组对人肾癌GRC-1细胞的生长抑制及促进凋亡作用强于其他处理组及对照组.结论 新型多聚体微泡携带舒尼替尼在超声作用下对人肾癌GRC-1细胞生长有明显抑制作用,并诱导细胞凋亡.%Objective To investigate the effect of growth inhibition and apoptosis induction of sunitinib-liposome-loaded microbubbles on renal carcinoma cell strain.Methods GRC-1 cell strain was cultured in vitro,and was divided into 6 groups:blank control group,pure microbubbles group,pure lipsomes group,sunitinib group,sunitinib-liposome-loaded microbubbles without ultrasound treat group,sunitinib liposome-loaded microbubbles with ultrasound treat group.Growth inhibition in different groups was observed at different time with MTT assay,apoptosis induction with Sigma-FlTC technology and transmission electron microscope.Results The growth inhibition and apoptosis promotion of GRC-1 cell were significantly increased in sunitinib-liposome-loaded microbubbles with ultrasound treat group compared to the other groups.Conclusions Microbubble guided sunitinih delivery can increase the effect of the growth inhibition and apoptosis induction of GRC-1 cells,which may provide an more effective approach for cancer treatment.
