Dr. Yu Liu is interested in the regulatory mechanisms of early embryonic development. At the early stages of life when the embryo comprises only a few hundreds of cells, cellular differentiation and organogenesis are highly dynamic and regulated by powerful factors such as pioneer transcription factors and non-coding RNAs. By learning these processes, Liu hopes to provide unique insights into human diseases and develop novel approaches to treat them.
Liu’s recent work on miR-322/503 exemplifies a typical approach. Using mouse genetic tools, the lab identified miR-322/503 as one of highest enriched microRNA clusters in early heart progenitor cells. Next, they learned that triggering the expression of miR-322/503 was sufficient to drive heart muscle cell differentiation in a cell culture system. Currently, Liu is using animal models to address how ectopic expression (transgenic) or deletion (knockout) of miR-322/503 affects normal heart function and the outcome of ischemic heart diseases.
