Hizikia fusiforme, a type of brown algae, is widely used in Asian cuisine. It has been reported to have various pharmacological effects. In this study, the effects of the ethanol extract from H. fusiforme (EAHF) on the proliferation of human colon carcinoma cells were investigated. The effect on the survival of human hepatocarcinoma and colon carcinoma cells was examined, and results revealed that the anti-proliferative effects of EAHF were higher in colon carcinoma cells than in hepatocarcinoma cells. The inhibition of proliferation of HT29 colon carcinoma cells by EAHF treatment was closely related to the induction of apoptosis. EAHF treatment also increased caspase activity and poly(ADP-ribose) polymerase degradation, induced mitochondrial dysfunction, altered Bcl-2 family protein expression, and increased the rate of cytochrome c released from the mitochondria into the cytoplasm. Furthermore, the production of reactive oxygen species (ROS) was markedly stimulated by EAHF treatment, and when ROS production was blocked, EAHF-induced cytotoxicity was significantly attenuated. These results indicate that the anticancer activity of EAHF in HT29 colon carcinoma cells was induced by ROS-dependent mitochondrial impairment. While EAHF exhibited potent anticancer activity in colon carcinoma cells in this study, further studies on the active components of EAHF and their efficacy should be performed.
