- Background/Aims
Parthenolide (PT) is responsible for the bioactivities of Feverfew. Besides its potent anti-inflammatory effect, this compound has recently been reported to induce apoptosis in cancer cells. Unfortunately, many of the therapies that use 5-fluorouracil (5-FU) alone or in combination with other agents are likely to become ineffective due to drug resistance. In the present study, we investigate the antitumor effect of PT combined with 5-FU on colorectal cancer cells. Methods: SW480 cell was employed as a representative of human colorectal carcinoma (CRC) cells. We performed MTT, annexin-V assay, and Hoechst 33258 staining to measure the synergistic effect. Western blotting was used to demonstrate apoptotic pathway. Results: Our result demonstrated that PT inhibited the viability of colorectal cancer cells and had synergistic anti-proliferation in combination with 5-FU. After combined treatment of 5-FU and PT, enhanced apoptotic cell death is observed using annexin-V FITC assay and it was revealed by the condensed chromatin and fragmented DNA. Compared with 5-FU or PT alone, the apoptosis of colorectal cancer cells treated with PT and 5-FU enhanced the activation of caspase-8, caspase-3. Conclusions: Combined treatment with PT may offer an efficacious strategy to overcome 5-FU resistance in certain CRC cells. (Intest Res 2012;10:357-364)
