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
