摘要:

目的:探讨肉桂油主要活性成分(E)-肉桂醛对人结肠癌LOVO细胞增殖、凋亡的影响及其分子机制。方法:采用CCK-8法测定(E)-肉桂醛对LOVO细胞增殖活性的影响。平板克隆形成实验检测(E)-肉桂醛对LOVO细胞克隆形成能力的影响。AnnexinV-PE/7-AAD双染色法测定(E)-肉桂醛对细胞凋亡的影响。Western blot分析细胞内凋亡相关蛋白Bcl-2、Bax、Caspase-3的表达水平。结果:(E)-肉桂醛能显著抑制结肠癌细胞LOVO的增殖活力和克隆形成能力(P<0.05),且细胞增殖抑制作用随时间的延长和剂量的增加而增强。与对照组相比(E)-肉桂醛作用LOVO细胞48 h后,细胞凋亡率升高(P<0.05)。Western blot检测结果显示(E)-肉桂醛作用LOVO细胞48 h后Bcl-2蛋白表达水平显著降低(P<0.05),Bax、Caspase-3表达水平明显增高(P<0.05)。结论:(E)-肉桂醛能抑制结肠癌细胞增殖并诱导凋亡,其机制可能是通过增加Bax、Caspase-3的活性及抑制Bcl-2的表达来实现的,(E)-肉桂醛是一种具有发展潜力的抗结肠癌药物。

Abstract:

AIM: To explore the effects of trans-cinnamaldehyde on proliferation and apoptosis of LOVO cells of colon cancer. METHODS: The cell proliferation was detected by CCK-8 assay, and clone forming ability of colon cancer cells was detected by colony formation assay. The cell apoptosis was assessed by flow cytometry, and the expression of Bcl-2, Bax, and Caspase-3 was detected via Western blot. RESULTS:Trans-cinnamaldehyde significantly inhibited the proliferation and clone forming ability of the colon cancer cells LOVO in vitro. Compared with the control group, apoptosis rate of LOVO cells was significantly increased in the trans-cinnamaldehyde group (P<0.05). Expressions of Bcl-2 and Caspase-3 were increased in the trans-cinnamaldehyde group, with fragmented Bcl-2. CONCLUSION: The trans-cinnamaldehyde can inhibit cell growth and induce apoptosis of LOVO cells, which involves the up-regulation of Bax and Caspase-3 and the down-regulation of Bcl-2. (E)-cinnamaldehyde is a potnetial anti-tumor target of colon cancer.

Key words: (E)-cinnamaldehyde, colon cancer, proliferation, apoptosis
