摘要: 应用雌激素受体阳性的人乳腺癌细胞株(MCF-7细胞),在体外培养条件下,观察三苯氧胺(TAM)和重组人白细胞介素-6(IL-6)对该细胞凋亡的影响。样品经碘化丙啶(PI)染色后用EPICS ELITE流式细胞仪测定并分析。结果表明,TAM和IL-6皆可诱导MCF-7细胞凋亡,与对照组相比具显着性差异(P<0.01).若将TAM和IL-6联合应用,其诱导MCF-7细胞凋亡数明显上升,与单药应用比较具非常显着性差异(P<0.01),提示2药合用的效果不是简单的加成而是协同作用。

Abstract: The effect of tamoxifen(TAM) and interleukin-6(IL-6) on apoptosis in estrogen receptorpositive human breast cancer cell line(MCF-7) was studied. The sample cells stained by propidium iodide(PI) were detected, analyzed and fitted by FCM. The result showed that TAM and IL-6 could induce apoptosis of MCF-7 cells, the difference of apoptotic ratio between the control group and the treatment group was significant respectively. The cell apoptosis was enhanced when combining treatment with TAMand IL-6 was performed. The increase rate is much higher than that of either TAM or IL-6 alone, the differences were significant. The data indicated that the effect of TAM combined IL-6 is not an additive interraction, but possibly a synergistic interraction.

Key words: TAM, IL-6, apoptosis, FCM, preast cncer
