Research Interest Summary

We study liver development and regeneration using zebrafish as a model organism.

Research Interests

Our long-term goal is to completely understand the molecular and cellular mechanisms underlying BEC-driven liver regeneration. As a first step in pursuit of that goal, we recently established and reported an innovative zebrafish liver regeneration model in which hepatocyte-specific ablation results in extensive BEC-driven liver regeneration. Using this model, we found that Wnt, Bmp and Fgf signaling play important roles in the regeneration process. Moreover, we identified candidate genes, which are upregulated during liver regeneration and may regulate liver regeneration, by comparing gene expression profiles during liver regeneration. We have been determining in detail the roles of the signaling pathways and the candidate genes in BEC-driven liver regeneration.

In addition to the liver regeneration studies, we study biliary morphogenesis. We recently found that proper biliary morphogenesis needs proper Wnt/β-catenin signaling. We have been investigating how Wnt/β-catenin signaling regulates biliary morphogenesis at the cellular and molecular levels. Moreover, as collaboration with Dr. Sindhi, a pediatric liver transplant surgeon at the Children’s Hospital of Pittsburgh, we discovered that Arf6, whose SNP variation is significantly associated with biliary atresia patients, is required for proper biliary morphogenesis. We have been investigating the molecular and cellular mechanisms by which Arf6 regulates biliary morphogenesis.
