Anticancer effects of kimchi fermented for different times and with added ingredients in human HT-29 colon cancer cells

Anticancer effects of kimchi fermented for different times and containing added ingredients in HT-29 human colon carcinoma cells were studied. Optimally ripened kimchi showed higher anti-proliferation activities than fresh and over-ripened kimchi. Anticancer-ingredients-added kimchi exhibited higher activities than standardized-recipe kimchi in HT-29 cells. Optimally-ripened anticancer kimchi suppressed expression of Bcl-2 and promoted expression of Bax, caspase-9, and caspase-3 to promote apoptosis, and reduced mRNA expressions of proinflammatory factors, exhibiting the strongest anticancer effect. Fermentation and ingredients are important factors to increase in vitro anticancer functionalities.
