Sept 2015: We receive an NIH R01 grant to unravel the mysteries of Heterochromatin repair!


We study how DNA is repaired in heterochromatin, which contains extensive repeated sequences prone to trigger aberrant recombination, chromosome rearrangements, and genome instability.

We discovered that heterochromatin repair requires surprising nuclear dynamics, including a dramatic relaxation/expansion of the entire heterochromatin domain and relocalization of repair centers to the nuclear periphery.

Our goal is to identify the mechanisms responsible for these dynamics and to understand how their disfunction contributes to human diseases, including cancer and several aging-related disorders.



In this artistic work by S. Colmenares, the heterochromatin compartment is depicted as the Sun. Heterochromatic ‘flares’ are released during repair to allow the recruitment of repair components (yellow and blue dots).
