My lab has been interested in addressing biological and clinical questions using mouse models that have direct relevancy to the understanding, prevention, and treatment of eye disease.

1. Role of Hippo/Yap1 in the eye– A recent major effort has focused on the function of Hippo/Yap1 pathway in eye. Hippo signaling pathway is an evolutionarily conserved pathway that regulate stem cell/progenitor cell proliferation, fate determination, or apoptosis during development and malignant cells in carcinomas. The importance of YAP1 to eye was illustrated recently, however, the mechanisms are currently not clear. We are studying the cellular specific function of YAP1 in the eye and its regulatory mechanisms using conditional knockout mice.
2. IKK2/NF-kB inhibition of angiogenesis– We recently discovered that inhibition of IKK2/NF-kB pathway significantly attenuated the laser induced choroidal neovascularization formation; therefore, establishing that targeting to this pathway is a good candidate to develop a novel alternative therapeutics. We are investigating the molecular and cellular mechanisms of IKK2/NF-kB inhibition of angiogenesis. Understanding the link between IKK2/NF-kB and NV may have broad clinical implications for many disease including AMD, diabetic retinopathy and tumor formation.
