摘要:

目的  探讨癌光啉(PSD-007)对人乳腺癌MCF-7细胞体外光动力杀伤效应。方法   噻唑蓝(MTT)比色法检测不同浓度PSD-007、不同能量光照MCF-7细胞的光密度(OD)值;以不同能量(1.2、2.4、4.8J/cm2)激光照射(分别为3个实验组)10μg/mL PSD-007孵育的细胞,彗星实验、DAPI染色观察细胞形态学改变,流式细胞术(FCM)分析细胞周期及细胞凋亡率,免疫印记(Western blotting)检测B细胞淋巴瘤/白血病-2蛋白(Bcl-2)、Bcl-2相关X蛋白(Bax)、半胱氨酸天冬氨酸蛋白酶-3蛋白(Caspase-3)表达量,同时设空白对照、单纯光照和单纯光敏剂组为对照组。结果   光动力治疗对MCF-7细胞有明显的杀伤效应。彗星图像可见明显慧尾存在。DAPI染色观察到细胞呈现典型的凋亡形态特征。FCM分析结果   显示,细胞凋亡率与空白对照组比较差异有统计学意义(P<0.05),凋亡率随光照能量增大而增高,G0/G1期细胞比例明显增加,细胞周期进程减慢。Western blotting结果   显示,相比对照组,实验组Caspase-3和Bax表达水平明显上调,而Bcl-2表达水平下调。结论    PSD-007对人乳腺癌细胞系MCF-7细胞具有光动力杀伤效应,其杀伤效应与Bcl-2、Bax、Caspase-3密切相关。

Abstract:

Objective   To investigate the photodynamic effect of PSD-007 on human breast neoplasm cell line MCF-7 in vitro. Methods  MTT assay was performed to examine MCF-7 cells treated with different concentrations of PSD-007 and different intensities of laser. Different intensities of laser (1.2, 2.4, 4.8J/cm2) were applied to treat MCF-7 cells with 10μg/mL of PSD-007. The morphological changes of MCF-7cells were observed with comet assay and DAPI staining. The cellular apoptosis rate and cell cycle phase distribution of MCF-7 cells were measured with flow cytometry (FCM). The relative expressions of Bcl-2, Bax, and Caspase-3 proteins were detected with Western blotting. The blank control group, pure laser group and pure photosensitizer group were established as controls. Results  Significant differences in the inhibitory effects were observed (P<0.05). The comet figure significantly observed the comet tail. The morphological study found that multinucleate giant cells existed in the apoptotic cells in PSD-007 PDT. The FCM assay showed that the apoptosis rates were obvious and the killing effect improved with the intensity of laser (P<0.05). The Results   of cell cycle analysis revealed a significant increase of the number of cells in G0/G1 phase. Compared with the control groups, Caspase-3 and Bax expressions were markedly up-regulated in the experiment groups, while Bcl-2 expression was significantly down-regulated. Conclusion  PSD-007 has a photodynamic effect on human breast carcinoma cell line MCF-7 in vitro, which is closely associated with Caspase-3, Bcl-2 and Bax.
