摘要: 为探讨胰腺癌细胞Ki-67与细胞凋亡的关系,通过1,25(OH)2D3诱发胰腺癌细胞株Bxpc-3凋亡,采用MTT法检测细胞增生情况,TUNEL法检测细胞凋亡指数,免疫组化法检测Ki-67阳性表达指数,并进行相关性分析。结果:在10-8mol/L1,25(OH)2D3诱发Bxpc-3凋亡过程中,肿瘤细胞凋亡指数与Ki-67阳性表达指数呈负相关。提示:对凋亡指数及Ki-67阳性表达指数的综合分析,可全面反映细胞凋亡和增生的平衡状态,对于判断肿瘤细胞的增生具有参考价值。

Abstract: To test the realtionship between Ki-67 index and apoptosis in the pancreas cancer cell line Bxpc-3, apoptosis was inducted by 1,25(OH)2D3 in the pancreas cancer cell line. We compared the cell number by MTT, determined quantitatively apoptosis cells by TUNEL, detected the expression of Ki-67 index by immunohistochemical. Results suggested that the expression of the Ki-67 index was decreased during apoptosis induced by 10-8mol/L 1,25(OH)2D3 in Bxpc-3 cell line. There was negative correlation between the apoptosis and the expression of Ki-67 index. Comprehensive analysis of the apoptosis and Ki-67 index reflects the balance of proliferation and apoptosis.

Key words: 25-(OH)2D3, Bxpc-3, apoptosis, Ki-67
