        摘  要   目的:研究溶瘤病毒M1(简称“M1病毒”)诱导宫颈癌细胞C-33A凋亡的作用及机制。方法:采用MTT法检测不同滴度
       (0、0.001、0.01、0.1、1、10 PFU/cell)M1 病毒处理后 C-33A 细胞的存活率;将 C-33A 细胞分为对照组(0 PFU/cell)和 M1 病毒低、
        中、高剂量组(0.001、0.01、0.1 PFU/cell),加入相应滴度病毒,培养48 h 后,采用流式细胞仪检测细胞的凋亡率和感染率,采用Western
        blot法检测细胞中C/EBP 同源蛋白(CHOP)、胱天蛋白酶12(caspase-12)、caspase-3、活化的caspase-3(cleaved-caspase-3)的表达水
        平。结果:经不同滴度M1病毒处理后,C-33A细胞存活率均显著降低(P<0.01),且呈剂量依赖趋势。与对照组比较,M1病毒各
        剂量组细胞的凋亡率和感染率以及中、高剂量组细胞中CHOP、caspase-12、cleaved- caspase-3(中剂量组除外)蛋白的表达水平均
        显著升高(P<0.01)。结论:M1病毒可诱导宫颈癌细胞C-33A的凋亡,其作用机制可能与激活内质网应激通路有关。

        ABSTRACT    OBJECTIVE:To study the effects and mechanism of oncolytic virus M1(called M1 virus for short)inducing the
        apoptosis of cervical cancer C-33A cells. METHODS:MTT assay was used to detect survival rate of C-33A cells that were treated
        with different titers(0,0.001,0.01,0.1,1,10 PFU/cell)of M1 virus. C-33A cells were divided into control group(0 PFU/cell),
        low-dose,medium-dose and high-dose groups of M1 virus(0.001,0.01,0.1 PFU/cell). After treated with corresponding titers of
        M1 virus for 48 h,flow cytometry was used to detect the apoptotic rate and infection rate of cells;Western blot was performed to
        detect the protein expression of C/EBP homologous proteins(CHOP),caspase-12,caspase-3 and cleaved-caspase-3. RESULTS:
        After treated with different titers of M1 virus,the survival rate of C-33A cells decreased significantly(P<0.01),and showed a
        dose-dependent trend. Compared with control group,the apoptotic rate and infection rate of cells in M1 virus groups as well as the
        protein expression of CHOP,caspase-12 and cleaved-caspase-3(except for medium-dose group)in M1 virus medium-dose and
        high-dose groups were increased significantly(P<0.01). CONCLUSIONS:M1 virus can induce the apoptosis of cervical cancer
        C-33A cells,and its mechanism may be related to the activation of endoplasmic reticulum stress pathway.
