| Research Abstract |
Recently, YAP was shown to play an important role in organ size control and to be inhibited by the Hippo signaling pathway. Either transgenic overexpression of YAP or knockout of Hippo pathway genes in mouse liver results in enlargement of this organ and the eventual development of hepatic tumors. In this study, we used the method of hydrodynamic tail vein injection (HTVi) that is specific for gene transfer into liver. As a results, we succeeded in establishing an efficient system of liver cancer induction due to gain of function of the active YAP. Secondly, we analyzed the gene expression by cDNA microarray and identified more than 20 genes whose expression is increased by active YAP. Thus, our results could contribute to elucidate the mechanism of human liver cancer.
