Background: Resveratrol has been reported to have potential chemopreventive and apoptosis-inducing properties in a variety of tumor cell lines. Objective: In this study, to investigate the effects of resveratrol on protein kinase C (PKC) activity and apoptosis in human colon carcinoma cells, we used HT-29 cells and examined the $PKC{\alpha}$ and ERK1/2 signaling pathways. Methods: To test the effects of resveratrol on the growth of HT-29 cells, the cells were exposed to varying concentrations and assessed with the the MTT cell-viability assay. Fluorescence-activated cell sorter (FACS) analysis was applieded to determine the effects of resveratrol on cell apoptosis. Western blotting was performed to determine the protein levels of $PKC{\alpha}$ and ERK1/2. In inhibition experiments, HT-29 cells were treated with G$\ddot{o}$6976 or PD98059 for 30 min, followed by exposure to $200{\mu}M$ resveratrol for 72 h. Results: Resveratrol had a significant inhibitory effect on HT-29 cell growth. FACS revealed that resveratrol induced apoptosis. Western blotting showed that e phosphorylation of $PKC{\alpha}$ and ERK1/2 was significantly increased in response to resveratrol treatment. Pre-treatment with $PKC{\alpha}$ and ERK1/2 inhibitors (G$\ddot{o}$6976 and PD98059) promoted apoptosis. Conclusion: Resveratrol has significant anti-proliferative effects on the colon cancer cell line HT-29. The PKC-ERK1/2 signaling pathway can partially mediate resveratrol-induced apoptosis of HT-29 cells.

Raw meat of mackerel (Scomber japonicus) was salted by refined, sun-dried, bamboo, and KC1-added bamboo salts. Antimutagenic activity on N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Ames test and growth inhibitory effects of AGS human gastric and HT-29 human colon adenocarcinoma cells were investigated using methanol extracts of the salted mackerels. Mackerel salted sun-dried, bamboo, and KC1-added bamboo salts used increased the antimutagenic activities against MNNG, however, the sample treated with refined salt reduced the antimutagenic activity. Inhibitory effects of the salted-mackerels on the growth of human cancer cells were increased as dose dependent pattern. Mackerel salted with refined salt activated the growth of AGS human gastric adenocarcinoma cells, but mackerel salted with sun-dried, bamboo, and KC1-added bamboo salts kept or increased anticancer effect compared to the raw mackerel. Mackerel salted with KC1-added bamboo salt led to the highest antimutagenic and anticancer activities. These results suggest that antimutagenic and anticancer effects of mackerel during manufacturing of the salted-mackerel could be enhanced by using different kind of salts such as bamboo, or KC1-added bamboo salts.
