Recently, we established a new IP6-containing solution, designated as T-IP6, produced by Taimatsu fermented rice germ. In this study, we examined the inhibitory effects of tumor-associated antigens secreted from a gastric cancer cell line (MKN-45) and a hepatocellular carcinoma cell line (HepG2) exposed to T-IP6. The tumor-associated antigens, such ascarcinoembryonic antigen (CEA) and protein induced by vitamin K absence or antagonists-II (PIVKAII), secreted from these cancer cell lines cultured with T-IP6 were significantly inhibited (P<0.01), compared with those in control cells (cultured without T-IP6) at 72 hrs, and this inhibition was accompanied by morphological changes, respectively. In addition, T-IP6 inhibited CEA and PIVKA-II in a dose-dependent manner. These findings suggest that T-IP6 has an immunoinhibitory and normalization effect in human cancer cells.},
