Solanum tuberosum Linnaeus cv Hongyoung, which represents red potato, was developed in Korea. Hongyoung is known to have anti-oxidant, anti-inflammatory, anti-viral, and anti-tumor properties, but no research has been conducted on the growth inhibition and apoptosis effects of hongyoung in YD-10B oral cancer cells. In this study, the combined treatment of hongyoung ethanol extract (HEE) and cisplatin were examined to determine its ability to inhibit cancer cell growth, induce apoptosis, and inhibit matrix metalloproteinases (MMP)-2 and MMP-9 cancer metastasis. The cell viability was investigated using a 2-(2-methoxy-4-nitrophenyl)-3-(4-nitrophenyl)-5-(2,4-disulfophenyl)-2H- tetrazolium monosodium salt (MTS) assay, and the ability to induce apoptosis was analyzed using an FACS analyzer. The mRNA expression and protein activity of MMP-2 and MMP-9 were measured via RT-PCR and zymography. The YD-10B oral cancer cells showed an increase in growth inhibition as the concentration of HEE increased. The combination of 200 μM cisplatin and 500 ㎍/ml HEE reduced the growth of the YD-10B oral cancer cells by more than 50% compared to cisplatin alone. When phorbol 12-myristate 13-acetate (PMA)-treated YD-10B oral cancer cells were co-treated with 200 μM cisplatin and 500 ㎍/ml HEE, both the mRNA expression and protein activity of the MMP-2 and MMP-9 decreased. In addition, the percentage of the sub-G1 phase, which indicates apoptosis ability, more than doubled when treated in combination with 200 μM cisplatin and 500 ㎍/ml HEE than when cisplatin alone was used. The results of this study therefore suggest the possibility of using a combination of HEE and cisplatin in the development of effective drugs to treat oral cancer.
