Gene regulation at transcriptional and post-transcriptional levels has been the central focus of my research program. While transcription initiation begins the process of gene expression, the post-transcriptional steps of RNA splicing, cleavage-polyadenylation, transport and stability all contribute to the type and final levels of protein that will be produced. In addition, these steps are coupled to each other, which can contribute to overall regulation. My lab has been studying several different model systems that allow us to address aspects of gene regulation including immunoglobulin gene expression during B lymphocyte development and, in collaboration with the lab of Brett Spear, liver development and disease. In liver, we have identified Zhx2 as a regulator of genes involved in lipid metabolism and genes that are misregulated during liver cancer.
