Thrilled to share a new important study from the lab, published today in @nature.com, showing how cohesin mediates efficient replication fork plasticity and stress response, using its loop extrusion activity to promote 3D contacts on replicating DNA: www.nature.com/articles/s41...

What if the much-debated mechanisms of PARP inhibitors vary greatly across tissues and tumor subtypes? Our new preprint reveals surprising links between replication fork dynamics and PARPi sensitivity across acute myeloid leukemia (AML) subtypes. www.biorxiv.org/cgi/content/...

Thrilled to share a new preprint from the lab, showing that active fork slowing and reversal is not confined to the damaged subnuclear compartment but rapidly extends throughout the nucleus, via non-canonical ATR signaling and modulation of MRN exonuclease activity. www.biorxiv.org/cgi/content/...

Non-canonical ATR signalling via NBS1 phosphorylation propagates fork slowing from stressed to unperturbed nuclear regions
DNA replication forks frequently encounter obstacles and remodel into four-way junctions to actively slow DNA fork progression. Fork slowing can also spread to undamaged forks via an ATR-dependent mec...
