The purpose of this study aimed at examining the antiproliferative effect of kimchi (kimchi B) adding mistletoe extract known as an anticancer function to improve the functions of kimchi. The study investigated the antiproliferative effect through hemocytometer counts and MTT assay, apoptosis induction through DAPI staining, and mRNA expression through RT-PCR using human lung carcinoma A549 cells. The standardized kimchi (Kimchi A) was used as a control group. As a result of hemocytometer counts and the MTT assay, it was found that kimchi samples inhibited the growth of A549 cells in a concentration-dependent manner. Kimchi B induced apoptosis in A549 cells through DAPI staining. The apoptosis induced by kimchi B was associated with the increase in the expression of pro-apoptotic Bax and with the decrease in the expression of anti-apoptotic Bcl-2 and Bcl-xL. Also, kimchi B influenced the increase in the expression of p21 mRNA, but did not have the effect on the expression of p53 mRNA. In conclusion, the antiproliferative effect of kimchi B was due to apoptosis induced by increasing Bax and decreasing Bcl-2, and increasing p21. The findings will be utilized to develop kimchi with the improved function for the patients having cancer.
