The research interest of our lab is focusing on animal development and human diseases by using zebrafish as a model organism. We have studied the functions of Notch and Wnt signaling in different developmental processes and disease context. Recently, the focus has gradually shifted to the IMGM thematic project: lipid metabolism and human diseases.

Ubiquitylation and deubiquitylation are important protein posttranslational modification. We have investigated this issue both in basic developmental processes and human diseases. In the future, we would like to examine the interactions and/or crosstalks between ubiquitylation/deubiquitylation and lipid metabolism-related human diseases.

Presently, the lab is focusing on Mindbomb (Mib), a novel component of Notch signaling, and Ugly duckling (Udu), a novel protein that is likely be required for DNA replication and other processes. The ongoing projects are

  • to study how Zranb1 and Mib1 modulate zebrafish convergent extension through regulating Ryk trafficking;
  • to study the mechanisms of Udu/GON4L on lipid metabolism and hepatocarcinogenesis;
  • to study the functions of zebrafish Udu protein in angiogenesis;
  • in collaboration with physician scientists to study migraine comorbidity and spinocerebellar ataxia;
  • to collaboratively study the cell specification of epidermal mucous cells
