[PDF][PDF] BRCA1 functions independently of homologous recombination in DNA interstrand crosslink repair

…, ML Kozak, JM Kim, N Wong, AJ López-Contreras… - Molecular cell, 2012 - cell.com
Brca1 is required for DNA repair by homologous recombination (HR) and normal embryonic
development. Here we report that deletion of the DNA damage response factor 53BP1 …

[PDF][PDF] Cyclin-dependent kinase inhibitor p21 controls adult neural stem cell expansion by regulating Sox2 gene expression

…, A Banito, E Gómez-Ibarlucea, AJ Lopez-Contreras… - Cell stem cell, 2013 - cell.com
In the adult brain, continual neurogenesis of olfactory neurons is sustained by the existence

Exploiting oncogene-induced replicative stress for the selective killing of Myc-driven tumors

M Murga, S Campaner, AJ Lopez-Contreras… - Nature structural & …, 2011 - nature.com
Oncogene-induced replicative stress activates an Atr- and Chk1-dependent response, which
has been proposed to be widespread in tumors. We explored whether the presence of …

The ATR barrier to replication-born DNA damage

AJ López-Contreras, O Fernandez-Capetillo - DNA repair, 2010 - Elsevier
Replication comes with a price. The molecular gymnastics that occur on DNA during its
duplication frequently derive to a wide spectrum of abnormalities which are still far from …

An extra allele of Chk1 limits oncogene-induced replicative stress and promotes transformation

AJ López-Contreras, P Gutierrez-Martinez… - Journal of Experimental …, 2012 - rupress.org
Replicative stress (RS) is a type of endogenous DNA damage that cells suffer every time they
duplicate their genomes, and which is further boosted by oncogenes. In mammals, the RS …

USP7 is a SUMO deubiquitinase essential for DNA replication

…, J Specks, AJ Lopez-Contreras… - Nature structural & …, 2016 - nature.com
Post-translational modification of proteins by ubiquitin (Ub) and Ub-like modifiers regulates
DNA replication. We have previously shown that chromatin around replisomes is rich in …

[PDF][PDF] A proteomic characterization of factors enriched at nascent DNA molecules

AJ Lopez-Contreras, I Ruppen, M Nieto-Soler, M Murga… - Cell reports, 2013 - cell.com
