用于治疗胶质母细胞瘤的新药的临床前试验通常使用细胞凋亡作为抗肿瘤效果的量度。目前,还没有一种可靠的方法来确定胶质母细胞瘤中的细胞是否凋亡。目前用于检测细胞凋亡的方法,包括末端脱氧核苷酸转移酶缺口末端标记、核形态学、DNA梯状、Annexin-V结合和Western印迹,在胶质母细胞瘤中是主观的、难以执行或难以定量的。Cytomeric bead array analysis for active caspase-3是最近发展起来的一种技术,它可以快速定量胶质母细胞瘤中的凋亡。他莫昔芬(TAM),一种用于治疗乳腺癌和最近用于脑肿瘤的药物,用于诱导人胶质母细胞瘤细胞系的凋亡。本研究表明TAM通过激活caspase-3诱导细胞凋亡。结果还揭示了TAM诱导胶质母细胞瘤中caspase-3活性的时间和剂量依赖性反应。流式细胞仪微球阵列提供了一种快速的技术,用于测量胶质母细胞瘤细胞凋亡和caspase-3活性的动力学。
Pre-clinical trials of novel drugs for the treatment of glioblastoma often use apoptosis as a measure of anti-tumor effect. Presently, there is no single reliable method to determine whether a cell is apoptotic in glioblastoma. The currently used methods for detecting apoptosis, including terminal deoxynucleotidyl transferase nick-end-labeling, nuclear morphology, DNA laddering, Annexin-V binding, and Western blotting, are subjective, difficult to perform or difficult to quantify in glioblastoma. Cytomeric bead array analysis for active caspase-3 is a recently developed technique, which may allow rapid quantitation of apoptosis in glioblastoma. Tamoxifen (TAM), a drug used in treating breast cancer and more recently for brain tumors, was used to induce apoptosis in human glioblastoma cell lines. This study showed that TAM induced apoptosis via caspase-3 activation. The results also revealed a time- and dose-dependent response of TAM induced caspase-3 activity in glioblastoma. Cytometric bead array provides a rapid technique for measuring apoptosis and the kinetics of caspase-3 activity in glioblastoma.
