摘要 目的 探讨热休克蛋白70(HSP 70)在人白血病细胞的表达。方法 人白血病细胞HL-60经42℃休克2 h,分别于休克后4、8、12、16、24、48 h收集细胞爬片,采用ENVISION免疫组织化学法检测HSP 70在细胞中表达;为明确热休克处理前后白血病细胞表达量变化,采用间接免疫荧光法定量分析细胞休克前及休克后12 h HSP 70表达;应用DNA倍体检测分析HSP 70表达与细胞周期关系。结果 免疫组织化学和免疫荧光检测显示热休克后白血病细胞中HSP70表达明显增加,以12 h达高峰;DNA倍体分析在整个细胞周期HSP 70均有表达,G1期与G2期表达量基本一致。与休克前相比,经热休克处理人白血病细胞HL-60中HSP 70表达明显增高;HSP 70表达与细胞周期并无明显关系。结论 初步了解白细病细胞HSP 70表达规律,为今后进行HSP 70抗原肽提取和纯化及抗癌免疫研究奠定基础。
