We evaluated the possible anticancer performance of a natural compound, goniothalamin (GTN), against human lung cancer using as a non-small cell lung cancer (NSCLC) cell line, H1299, as the model system. Cellular proliferation was significantly inhibited by GTN. Using an improved alkaline comet-nuclear extract (comet-NE) assay, GTN was found to induce a significant increase in the tail DNA. Wound healing and zymography assays showed that GTN attenuated cell migration and caused a reduction in the activity level of two major migration-associated matrix metalloproteinases, MMP-2 and MMP-9. It can be concluded that the DNA-damaging effect of GTN against lung cancer cells leads to growth inhibition as well as a depression in migration ability. Therefore, GTN has potential as a chemotherapeutic agent against lung cancer.
我们评估了一种天然化合物戈尼辛(GTN)对人肺癌的可能抗癌性能,使用非小细胞肺癌(NSCLC)细胞系 H1299 作为模型系统。细胞增殖被 GTN 显著抑制。使用改良的碱性彗星-核提取物(彗星-NE)测定法,发现 GTN 诱导尾 DNA 显著增加。划痕愈合和酶谱分析表明,GTN 减弱了细胞迁移,并降低了两种主要迁移相关基质金属蛋白酶 MMP-2 和 MMP-9 的活性水平。可以得出结论,GTN 对肺癌细胞的 DNA 损伤作用导致生长抑制和迁移能力下降。因此,GTN 有可能成为一种治疗肺癌的化疗药物。
