APC (80-90%) and K-Ras (40-50%) mutations frequently occur in human colorectal
cancer (CRC) and these mutations cooperatively accelerate tumorigenesis including
metastasis. In addition, both ?-catenin and Ras levels are highly increased in
CRC, especially in metastatic CRC (mCRC). Therefore, targeting both the
Wnt/?-catenin and Ras pathways could be an ideal therapeutic approach for
treating mCRC patients. In this study, we characterized the roles of KY1022, a
small molecule that destabilizes both ?-catenin and Ras via targeting the
Wnt/?-catenin pathway, in inhibiting the cellular events, including EMT, an
initial process of metastasis, and apoptosis. As shown by in vitro and in vivo
studies using APCMin/+/K-RasG12DLA2 mice, KY1022 effectively suppressed the
development of mCRC at an early stage of tumorigenesis. A small molecular
approach degrading both ?-catenin and Ras via inhibition of the Wnt/?-catenin
signaling would be an ideal strategy for treatment of mCRC.
