| 摘 要： | 我们已从文蛤肉中提取得到1种具有抗癌活性的多肽，命名为Mer2．本文报道Mer2对体外培养的肺癌A549细胞的生物学效应．采用溴化二苯偶氮盐（MTT）法检测Mer2对肺癌A549细胞的抑制效果，并应用细胞形态观察法、Hoechst荧光染色和流式细胞术等方法，探讨了Mer2对细胞形态、细胞周期的影响．结果表明，Mer2对体外培养的肺癌A549细胞的生长有较强的抑制作用，对作用含量和时间均具有一定的依赖性．Met2使细胞形态发生明显变化，明显地出现凋亡峰，但并没有出现明显细胞周期阻滞现象．这表明文蛤多肽可能通过诱导细胞凋亡从而抑制癌细胞的生长．

| Abstract: | An anticancer peptide named as mer2 was purified from Meretrix meretrix.In this paper,we investigated its biological effect on the lung adenocarcinoma A549 cells.The effect of Mer2 on the growth of A549 cells was detected by MTT assay,and the morphology and the cell-cycle of cells were detected by optical microscope,Hoechst staining and flow cytometry.The results showed that Mer2 inhibited the growth of A549 cells in a dose-and time-dependent manner and cell morphology changed distinctly,showing an obvious apoptotsis properties.It indicated that the inhibitory effect of the peptide on cells had a relationship with the cell apoptotsis. |
