Abstract 649: Alpha -Santalol, a component of sandalwood oil inhibits migration of breast cancer cells by targeting beta-catenin pathway

Alpha-santalol, a terpenoid found in sandalwood oil has been shown to inhibit breast cancer cell growth in vitro by inducing apoptosis but the mechanisms underlying the growth inhibitory effects of alpha-santalol are not fully understood. In this study, we demonstrate that alpha-santalol treatment targets Wnt/beta-catenin pathway to inhibit migration of cultured breast cancer cells. Exposure of MDA-MB 231 and MCF-7 cells to alpha-santalol resulted in a significant reduction in their migratory potential and wound healing ability. In addition alpha-santalol affected the localization of beta-catenin from cytosol to nucleus in MDA-MB 231 cells. In conclusion, the present study indicates that alpha-santalol inhibited migration of breast cancer cells may be mediated in part by targeting Wnt//β-catenin pathway, and that beta-catenin represents an important target of alpha-santalol’s response for future pre-clinical studies.
