A fascinating aspect of all cells is their complex intracellular organization. Cells are subdivided in different compartments to organize cellular functions by physically separating biological reactions.
This compartmentalization is fundamental to regulate gene expression both in space and time. To understand how cells dynamically control gene expression to adapt to changing environments, we use single molecule mRNA imaging technologies both for fixed and living cells. These methods allow us to follow the entire mRNA life, from transcription to degradation, from the nucleus to the cytoplasm. Using these tools, we measure, with high spatial and temporal resolution, each stage of gene expression in individual cells. We study the coordination between the different stages of gene expression, to understand how cells tune gene expression to improve their fitness. By looking at single cells, we can assess how gene expression noise and cell-to cell variability affect cellular functions.
Using cell cycle mRNA as a paradigm and S. cerevisiae as a model system, we study how cells coordinate mRNA localization, translation and decay to achieve precise gene expression regulation.

To study gene expression in single cells, we continuously develop fluorescence-based imaging tools to visualize single mRNAs in fixed and living cells.
For fixed cells, we developed a single molecule fluorescent in situ hybridization protocol combined to immuno-fluorescence for S. cerevisiae.
For living cells, we previously developed a new RNA tagging system (MS2V6) that allows us to tag individual mRNAs in S. cerevisiae and that, compared to previous reporters is particularly suited to tag unstable mRNAs. See: https://doi.org/10.1038/nmeth.4502 and https://doi.org/10.1038/s41596-018-0037-2
We study how the mRNA localization, translation and decay are coordinated within individual cell, by combining imaging, molecular biology, genetics and biochemistry.
We are particularly interested in understanding how cell cycle regulated genes such as the ASH1 mRNA tune their expression to control growth and maximize fitness.
