We all begin our journey in life as single fertilized cells that divide into millions of progeny cells. Our transformation into complex bodies is driven by the RNAs that are expressed from our genes. These RNAs serve as instructions that tell cells where to go, as well as what to become (e.g. brain, skin). My research interests lie in understanding how cells regulate RNA activity. It has been shown that the precise regulation of RNA stability is important for healthy development, leading to the following questions. How do cells remove previous RNAs to enable new developmental gene programs? What cellular factors in the embryo dictate how long an RNA persists? Finally, how does the production and/or removal of different RNAs impact a cell’s decision to divide, move, or become a particular cell type? To answer these questions, my lab utilizes the zebrafish model system to study the role of RNA regulation within the context of early development and brain morphogenesis.
Why zebrafish? Zebrafish are becoming a very popular model organism to study almost every aspect of cell and developmental biology. Zebrafish can generate hundreds of embryos in a single morning that are easy to collect and study. The embryos develop rapidly and are transparent, allowing for real-time imaging of cellular processes. In addition, the genome is sequenced, and many genetic tools, such as CRISPR-based genome editing, work exceptionally well in this model organism. In my lab, we couple these tools with biochemical techniques and microscopy to understand how gene regulation shapes biological form. Ultimately, we hope that the insights gained from this work will inform our understanding of human health and disease.
