Abstract
- Fucoxanthin (Fx), one of the major xanthophylls in brown algae, is known to be effective for colorectal cancer (CRC) chemoprevention through inhibiting cell growth, cell cycle and caspase activation. Recently, we observed fucoxanthinol (FuOH), an anti-cancer active metabolite of Fx, treatment of human CRC cells resulted in plenty of living floating cells several hours after exposure, and induced apoptosis. In the present study, we investigated whether FuOH induced anchorage-dependent apoptosis, that is "anoikis", along with integrin signal suppression in human CRC cells. We found that cells exposed to 2.5 μM FuOH clearly showed anti-proliferative and apoptotic effects to DLD-1 cells, human CRC cells. FuOH treatment of DLD-1 cells led to an increase in anoikis-like changes represented by Calcein AM negative/ethidium homodimer-1 positive cell and living floating cells. Moreover, FuOH decreased FAK activation, and altered integrin β1 expression and distribution after 6 h treatment. After 24 h, the cells decreased PPARγ expression and Akt activation and increased integrin β1 expression. Our findings suggested that FuOH can induce anoikis in CRC cells through suppression of integrin signals in human CRC cells.
