About Dr.Wang's Research

The making of a mammalian heart requires orchestrated development and differentiation of multiple cell lineages. Chromatin factors play critical roles in this process by regulating gene expression and hence cell fate in various cell populations. After birth, chromatin factors continue to regulate the physiological properties of the heart, both at the cellular level and the organ level.

Our lab is interested in the role of two special families of chromatin factors - the Polycomb Group (PcG) and Trithorax Group (TrxG) proteins - in heart development, disease, and repair. We have established a mutant mouse model for the PcG gene Asxl2. We are pursuing research in two major directions using mouse models and cell culture:

1) The role of Asxl2in the epigenetic maintenance of adult heart function.

2) Regulation of progenitor activity and cardiac regenerative ability by chromatin factors in the adult heart.
