Overview

The Li Lab seeks a molecular understanding of how cells control the spatial organization of gene expression. We use advanced single-molecule imaging techniques to study the precise localization of mRNAs and proteins, and to understand how their disruption can lead to disease.  

For instance, in yeast, approximately 20% of all the mRNAs are targeted to the surfaces of the endoplasmic reticulum (ER) and mitochondria, where they are translated to support organelle biogenesis and homeostasis. In neurons, certain mRNAs are transported to synapses, where they play essential roles in synaptic activity and learning. Dysregulated mRNA localization in neurons is associated with neurological disorders, including fragile X syndrome (FXS) and amyotrophic lateral sclerosis (ALS). 

Through a combination of cell biology, biochemistry, biophysics and mathematical modeling, we strive to reveal fundamental principles governing the spatial regulation of gene expression and its implications for health and disease.
