Research Abstract

We generated hepatic cancer mouse model by inducing expression of activated Kras and ablation of Pten under albumin-promoter. The mice died from multipe liver tumor in 7 to 8 weeks. Using genomic analysis of SNP array, we found that Hippo pathway, a novel intracellular signaling, was involved in hepatocarcinogenesis. Aberration of SAV1, a component of the pathway, was shown to induce the activation of YAP/TAZ and following expression of CTGF in a liver cancer cell line.
