Biography

Andres Ramos has a PhD from Cambridge University and the Laboratory of Molecular Biology (LMB) and has undergone post-doctoral training at the MRC National Institute for Medical Research, in London. In 2004 he established his independent research group at NIMR and was tenured in December 2009. Since October 2013 he is Professor of RNA Biology in the Research Department of Structural and Molecular Biology at UCL.

Research Summary

The regulation of mRNA metabolism, transport and translation expands genomic diversity and provides a layer of control of gene expression essential for the development of complex organisms.

A key area of research in our group is the regulation of mRNA transport and local translation in neuronal development and function. Establishing and maintaining the complex network of connections required for neuronal communication requires the regulated transport of hundreds to thousands of mRNAs to specific locations in the cell and their in situ translation. RNA-binding proteins mediate the interaction of the mRNAs with the machines of cellular transport, as well as the regulation of the mRNAs’ translation control. We use a combination of newly designed and established structural and biophysical methods in combination with cell-biology tools to describe the protein-protein and protein-RNA interactions and build mechanistic models for this regulation. Importantly, mis-function or mis-expression of the proteins regulating local mRNA translation in neurons is at the basis of neuro-developmental and neuro-degenerative disorders. A molecular understanding of the regulatory pathways is key to exploit the potential of mRNA local translation in diagnosis and therapy.

A second area of research is the regulation of miRNA biogenesis and transport. miRNAs are short, single-stranded RNA molecules that direct silencing complexes to the target mRNAs. miRNA-mediated regulation  confer robustness to gene expression programs in development and in cell differentiation. The complex biogenesis of miRNAs is regulated by a number of RNA-binding proteins and we use the inter-disciplinary strategy outlined above to define how these proteins regulate miRNA biogenesis and how the mature miRNAs are transported to mediate inter-cellular communication. Understanding the mechanisms underlying miRNA biogenesis and transport provides an entry point to manipulate the miRNAs concentration and their loading into delivery vessels.


Teaching Summary

Andres Ramos is responsible for a lecture series on the methods to study the structure, dynamics and interactions of macromolecules and macromolecular assemblies (module BIOC1007).


He also teaches on gene regulation and RNA biology and in particular on the biogenesis, function and networks of miRNAs, on mRNA transport and localised translation and on the assembly and regulation of the RNA polymerase II complex (BIOC3024 and BIOC3014 respectively).
