The potential for forming a new organism begins at fertilization, when the sperm meets the egg. Across species from the worm to the human, development of the newly fertilized egg to a juvenile or an adult requires the careful regulation of cell growth, differentiation, and morphogenesis. Different cell types make different sets of proteins, even when their genomes are identical. What makes each cell type unique is a direct result of differential gene expressions mediated by transcription factors and signaling molecules in response to chemicals and proteins in the cell and the environment. Dysregulation of important genes involved in developmental decisions can lead to human diseases. Our research addresses one of the fundamental questions in developmental biology: How are genes regulated during early development? My laboratory investigates the regulatory roles of microRNAs (miRNAs) in early development. miRNAs are a class of non-coding RNA molecules that have recently been discovered to repress gene expressions in animal cells. miRNAs are critical for many aspects of life, including the development of an organism and physiological functions of cells and tissues.
