The results showed that the cell cycle and cytoskeleton may contribute to the CNE 2Z cells apoptosis induced by the inhibitors of protein kinase C.

结果表明，SS、ST可诱导CNE2Z细胞凋亡，细胞周期和骨架在细胞凋亡时，均发生了明显改变。

AIM To study the effects of homoharringtonine ( HHT ) on inhibition of proliferation and induction of apoptosis of nasopharyngeal carcinoma cells CNE 2Z .

目的探讨高三尖杉酯碱（homoharringtonine，HHT）对鼻咽癌细胞CNE2Z的增殖抑制和凋亡诱导作用。

The antitumor effect of coixenolide ( CXL ) was studied with human nasopharyngeal carcinoma CNE 2Z in vitro by MTT assay .

采用MTT法和活细胞计数法观察薏苡仁酯（Coixenolide，CXL）对人鼻咽癌细胞CNE－2Z生长的影响。

These results indicated that mutate p53 gene in CNE 2Z cells showed a high expression and it reduced markedly by inhibiting the PKC activity or reducing the PKC content .

以上结果表明：突变型p53基因在CNE－2Z细胞中有较高表达；通过抑制细胞PKC活性和耗竭PKC含量后，均可降低p53基因的表达；

Methods : After CNE 1 and CNE 2Z cells were treated with dauricine and piperine for 24,48 and 72 hours respectively , IC 50 values were determined by MTT assay .

方法：用MTT法测定两种药物分别处理CNE1、CNE2Z细胞株24、48、72h的IC50值。

Conclusion Caspase 6 and 8 take part in the course of the HHT induced apoptosis of CNE 2Z cells . The increase of Caspase 6 and 8 activities is in a time and concentration dependent manner .

结论Caspase6、8参与了HHT诱导的CNE2Z细胞凋亡，且其活性升高有时间和浓度依赖性。

The transverse velocity distribution accords with the exponential function distribution . the relation between the relative velocity v / vm and the relative position 2Z / B and the change range of coefficients m and n are determined .

横向流速分布符合指数函数分布，得到了相对流速v/vm与相对位置2Z/B之间的相关关系和系数m、n的变化范围。

By using DNA electrophoresis , flow cytometry ( FCM ) analysis and laser confocal microscopy ( LCM ), the change of cell cycle and cytoskeleton of CNE 2Z cells induced by the inhibitors of protein kinase C ( PKC ) were observed .

采用DNA电泳、PI染色流式细胞仪（FCM）分析和激光共聚焦显微镜（LCM）观察，检测了蛋白激酶C（PKC）抑制剂诱导CNE2Z细胞凋亡时细胞周期和骨架的改变。
