Outline of Final Research Achievements

We identified fluvastatin, dasatinib, pazopanib as agents inhibiting the function of oncogenic transcriptional co-activator, YAP/TAZ. They activate Hippo pathway and inhibit their nuclear localization. The sensitivity to these drugs of breast and colon cancer cell lines were correlated with the dependence on YAP/TAZ. Combination of these drugs efficiently reduced viability of MDA-MB-231 breast cancer cell lines. Furthermore, combination of these drugs with classical anti-cancer drugs synergistically reduced the viability of MDA-MB-231. These results suggest that these agents are effective for breast cancer cells with YAP/TAZ activation.
