Legnini Group

Laboratory for Molecular and Systems Biology of RNA

 

The Legnini Group at Human Technopole combines molecular and systems biology approaches to study gene regulation.

We use synthetic biology and optogenetics to engineer cells and organoids with the aim of reproducing complex regulatory cascades, then apply integrative transcriptomic readouts to understand the principles of gene regulation, with a particular focus on post-transcriptional regulation of RNA.

For example, we apply single-cell and spatial transcriptomics to organoid models of neurodevelopment, where we perturb gene expression with spatio-temporal resolution using optogenetics and study the spatial patterning of gene expression in a complex cellular environment.

At the same time, we look into the molecular detail of RNA regulation, from processing to degradation, by using and developing high-throughput and high-resolution transcriptomic technologies and quantitative models of RNA metabolism. In this regard, we for example use long-read sequencing methods to study how the same gene produces different mRNAs, and how regulatory elements in mRNAs such as 3’UTRs and poly(A) tails impact on RNA abundance and function.

    Regulation of mRNA metabolism in immune cells

    Rapid activation of immune cells is critical for host defence. While transcriptional regulation is essential for initiating the immune response, emerging evidence highlights the role of post-transcriptional mechanisms in controlling the speed and intensity of the immune reaction. Splicing, polyadenylation, translation and decay are all regulated to fine-tune the expression of genes crucial for immune […]
