Biosketch

Research in my laboratory is focused on understanding the mechanisms of cardiovascular development and promoting adult heart regeneration. Ventricular myocardial morphogenesis is a critical and complicated process during early heart development. Interestingly, a number of key signals for myocardial development such as Neuregulin 1 are transmitted from the endocardium, a single layer of endothelial cells that line along the trabecular myocardium. However, it is not well understood how these signals are initiated at the endocardium in the first place. We hypothesize that the epigenetic modifications occurring in the endocardium might be one of the early key regulatory steps that define/guide the later trabecular myocardial development. We are currently actively testing this hypothesis.

Improving heart regeneration still poses a huge research challenge to us, since the adult heart is one of the least regenerative organs in mammals. To tackle this question, we have generated a new mouse tool, AurkbER Cre/+, for quantifying adult cardiomyocyte proliferation, which has been quite difficult in the past, due to the rarity of proliferation events and the propensity of multinucleation in adult cardiomyocytes. This new mouse tool will allow us to more precisely quantify adult cardiomyocyte proliferation in a retrospective manner. Meanwhile, by using this mouse tool, we will be actively testing a few top hits from an in vitro small molecule library screening to see whether these molecules can improve heart regeneration in vivo and we will continue to study the potential underlying molecular mechanisms. Undoubtedly, the discovery of new drugs will pave new avenues for clinically promoting heart regeneration.
