Garaycoechea: Metabolic mutagenesis

Back to research groups

The Garaycoechea group studies how the interaction between metabolism and DNA repair leads to mutation in a physiological setting.

DNA carries the instructions of life, but is also under constant attack. The resulting damage, if not repaired, leads to mutation and disease. Common environmental mutagens include sunlight and cigarette smoke, but the integrity of DNA is also threatened by chemicals produced by our own body. Our group wants to understand what are the metabolites that arise within cells that damage DNA, and the consequences of this damage. Particularly, we are interested in understanding the maintenance of genome stability in stem cells, the rare cell populations responsible for tissue maintenance.

Group leader

Juan Garaycoechea

Juan Garaycoechea began his scientific career in Argentina, where in 2010 he obtained a first-class degree in Biotechnology from Universidad Nacional de Quilmes. He was then awarded the César Milstein scholarship to carry out his PhD studies at the MRC Laboratory of Molecular Biology (LMB), in Cambridge, UK. At the end of his studies, Juan was awarded a Junior Research Fellowship by King’s College, Cambridge to support his post-doctoral research at the LMB. He is a group leader at the Hubrecht Institute from October 2018, where he studies the metabolites that damage DNA and how this leads to mutation in a physiological context.
