摘要: 目的 探讨视神经萎缩蛋白1(OPA1)在双硫仑联合铜(DSF-Cu)诱导舌癌细胞凋亡中的作用。 方法 用不同浓度的DSF-Cu干预舌癌细胞Cal-27,MTT法检测细胞增殖活性,Annexin V-FITC/PI染色结合流式细胞仪检测细胞凋亡,荧光素酶发光法检测ATP含量,Western blot法检测OPA1蛋白表达水平。 结果 DSF-Cu能抑制舌癌细胞的增殖活性,促进细胞凋亡的发生,减少细胞ATP含量,并呈浓度依赖性。Western blot结果示低浓度DSF-Cu对OPA1蛋白表达无明显影响,而中、高浓度的DSF-Cu显著抑制OPA1蛋白表达水平。 结论 DSF-Cu可诱导舌癌细胞凋亡,其机制可能是通过抑制OPA1表达。

Abstract: Objective To investigate the effect of disulfiram combination with cooper (DSF-Cu) on the apoptosis of Cal-27 cells and its relation with optic atrophy 1 (OPA1). Methods The Cal-27 cells were treated with various concentrations of DSF-Cu. Cell viability was evaluated by MTT assays. The apoptosis rate was analyzed by flow cytometry. The protein expression level of OPA1 was detected by western blotting. Results As compared with control group, DSF-Cu decreased the number of viable cells.Flow cytometric analysis showed an increase in the incidence of apoptosis. What’s more, the content of ATP was decreased significantly. Western blot results showed the expression of OPA1 was markedly decreased in high and medium concentration group, but no significant change in low concentration group. Conclusions DSF-Cu can induce apoptosis of Cal-27 cells, which may be achieved by inhibiting the expression of OPA1.

Key words: disulfiram, tongue carcinoma cell, OPA1, apoptosis
