Research Area

The Hippo pathway has emerged as a critical developmental pathway contributing to processes that regulate tissue growth and organ size. Our research group aims to characterize the regulation and physiologic functions of the Mst1 and Mst2 protein kinases, which are the mammalian orthologs of the “hippo” kinase. Recently, we have made several exciting discoveries regarding the physiological functions of these two kinases. At first, we conditionally deleted both of Mst1 and Mst2 in the developing mouse liver. Within a few weeks, these mice exhibit a dramatic expansion of undifferentiated cells that resemble bipotential liver progenitors. Remarkably, these mice invariably go on to develop both hepatocellular carcinoma and cholangiocarcinoma within four months. In addition, the combined deletion of Mst1 and Mst2 from the hematopoietic compartment results in the absence of all peripheral lymphocytes and a profound immunodeficiency syndrome. The liver phenotype reflects an essential, overlapping function of Mst1 and Mst2 in the negative regulation of liver cell proliferation, whereas the lymphocyte cell phenotype reflects predominantly the loss of Mst1/2-mediated regulation of cell adhesion and migration. The identification of the molecular elements upstream and downstream of the Mst1/2 kinases for each of these functions is the focus of present effort.
