摘要: 摘要: 目的 探讨香芹酚 (CV) 对人非小细胞肺癌 (NSCLC) NCI-H1299 细胞的增殖、 凋亡及侵袭的作用及可能机制。方法 以不同浓度的 CV (20、 40、 60、 80 μmol/L) 处理 NCI-H1299 细胞, 以未经 CV 处理的细胞为对照组。采用四甲基偶氮唑蓝 (MTT) 比色法检测细胞存活率; 流式细胞术检测各组细胞凋亡率; Transwell 法检测 40 μmol/L CV 处理组和对照组细胞侵袭能力; 实时荧光定量 PCR 及 Western blot 检测 40 μmol/L CV 处理组和对照组的半胱氨酸天冬氨酸蛋白酶 (caspase) -9、 基质金属蛋白酶 (MMP) -9、 TIMP-1 的 mRNA 及蛋白水平的表达变化。结果 与对照组比较, CV 各处理组 NCI-H1299 细胞存活率均明显降低, 而凋亡率增加 (P<0.05), 但抑制效应均不呈浓度依赖性(P>0.05)。CV 处理组侵袭细胞数 (40.67±3.63) 个明显低于对照组 (76.00±5.78) 个 (P<0.01)。CV 处理组较对照组 caspase-9、 TIMP-1 的 mRNA 和蛋白表达水平均增高, MMP-9 的 mRNA 和蛋白表达水平均降低 (P<0.01)。结论 CV 可诱导人 NSCLC NCI-H1299 细胞凋亡, 抑制其侵袭, 作用机制可能与 caspase-9 的活性增加及 MMP-9 的下调有关。

Abstract: Abstract:Objective To study whether carvacrol can cause apoptosis in non-small cell lung cancer (NSCLC) cell line NCI-H1299, and explore its possible molecular mechanism. Methods NCI-H1299 cells were treated with different concentrations of carvacrol (20, 40, 60 and 80 μmol/L) for 24 or 48 h. The viability of cells was evaluated by MTT assay, apoptosis was analyzed by flow cytometry (FCM) and the effect of carvacrol on metastasis of NCI-H1299 was analyzed by Transwell assay. The expression level of caspase-9, MMP-9 and TIMP-1 were detected by quantitative realtime-PCR and Western blot assay. Results After treatment with carvacrol, the viability of NCI-H1299 cells was suppressed dramatically (P<0.05), without dose-dependent manner (P>0.05). After being incubated with carvacrol for 24 h, FCM analysis indicated that carvacrol effectively induced apoptosis in NCI-H1299 cells (P<0.05), without dose-dependent manner (P>0.05). The ability of invasion was decreased (40.67±3.63 vs. 76.00±5.78). Carvacrol inhibited the protein and mRNA expression levels of caspase-9, but increased the expression of MMP-9 and TIMP-1 (P<0.05). Conclusion Carvacrol can induce apoptosis of NCI-H1299 cells and inhibit their invasion, which may be associated with up-regulation of caspase- 9 expression and down-regulation of MMP-9 expression.
