| Research Abstract |
To clarify the effect of blocking Wnt signaling in mesothelioma, we down-regulated the expression of dishevelled (Dvl), an intermediator of Wnt signaling, by a small interfering RNA (siRNA). Mesothelioma cell lines were transfected with siRNA of Dvl, and cell growth was examined. The synergistic effect on cell growth of Dvl siRNA and cisplatin in combination was evaluated. Dvl siRNA down-regulated the expression of Dvl in mesothelioma cells, which caused suppression of cell growth. Combination of Dvl siRNA and cisplatin suppressed cell growth synergistically. Our data suggest that inhibition of Wnt signaling leads to significant anti-tumor effects.
