Research Interests

 

My lab is interested to understand how stem cells control their self-renewal and differentiation, and how their disregulation causes diseases. We use the intestine and reproductive system as two in vivo systems to address this question. Genetically engineered mice are our research tools due to the fact that mice have close genetic and physiological similarities to humans. Our ongoing projects are to study an RNA binding protein, PTB (polypyrimidine tract binding protein), in regulating stem cell-based tissue regeneration. PTB is known for its role in regulating gene’s post-transcriptional regulation, especially those that are critical for stem cell renewal and differentiation. Our recent studies using PTB conditional knockout mice indicate that PTB’s function is essential for the control of intestinal epithelium regeneration and fertility. We are currently using these knockout mice together with other available mouse lines to address how PTB-dependent post-transcriptional regulation controls stem cell-based tissue regeneration in the intestine and reproductive system.

show listCurrent Projects

There are three ongoing projects in the lab: 

The first one is to determine how PTB-dependent post-transcriptional regulation inhibits inflammatory bowel disease and its associated colorectal cancer.  

The second one is to determine how PTB controls spermatogenesis through its function in sertoli cells.

The third one is to determine how PTB controls female reproductive function through its role in progesterone receptor-expressing cells.
