Medical Degree: Peking Union Medical University, China
BS: Peking Union Medical University, China
Projects: Interplay between butyrate, a microbe-derived short chain fatty acid, and c-Myc regulates expression of pro-proliferative miRNAs in colon cancer.  Compromised colonic butyrate production resulting from low dietary fiber or altered bacterial flora may promote colon neoplasia. Since butyrate suppresses expression of the oncogenic miRNA clusters and families, we sought to identify a role for this effect in colon cancer and elucidate the underlying mechanisms.  My project focuses on the regulatory effects of butyrate on miRNA biogenesis and the down-stream miRNA targets.
