Targeting the centriolar replication factor STIL synergizes with DNA damaging agents for treatment of ovarian cancer
(Impact Journals, 2017)
Advanced ovarian cancer is an incurable disease. Thus, novel therapies are required. We wished to identify new therapeutic targets for ovarian cancer. ShRNA screen performed in 42 ovarian cancer cell lines identified the ...

PHF2 regulates homology-directed DNA repair by controlling the resection of DNA double strand breaks
(Oxford University Press, 2020)
Post-translational histone modifications and chromatin remodelling play a critical role controlling the integrity of the genome. Here, we identify histone lysine demethylase PHF2 as a novel regulator of the DNA damage ...

BRCA1 Accelerates CtIP-Mediated DNA-End Resection
(Elsevier, 2014)
DNA-end resection is a highly regulated and critical step in the response and repair of DNA double-strand breaks. In higher eukaryotes, CtIP regulates resection by integrating cellular signals via its posttranslationa ...

CtIP-mediated Alternative mRNA Splicing Fine-tunes the DNA Damage Response
(Cold Spring Harbor Laboratory Press, 2021)
In order to survive to the exposure of DNA damaging agents, cells activate a complex response that coordinates the cellular metabolism, cell cycle progression, and DNA repair. Among many other events, recent evidence has ...

CDK targets Sae2 to control DNA-end resection and homologous recombination
(Nature Publishing Group, 2008)
DNA double-strand breaks (DSBs) are repaired by two principal mechanisms: non-homologous end-joining (NHEJ) and homologous recombination (HR)1. HR is the most accurate DSB repair mechanism but is generally restricted to ...

Nuclear poly(A)-binding protein 1 is an ATM target and essential for DNA double-strand break repair
(Oxford University Press, 2018)
The DNA damage response (DDR) is an extensive signaling network that is robustly mobilized by DNA double-strand breaks (DSBs). The primary transducer of the DSB response is the protein kinase, ataxia-telangiectasia, mutated ...

Competing roles of DNA end resection and non-homologous end joining functions in the repair of replication-born double-strand breaks by sister-chromatid recombination
(Oxford University Press, 2013)
While regulating the choice between homologous recombination and non-homologous end joining (NHEJ) as mechanisms of double-strand break (DSB) repair is exerted at several steps, the key step is DNA end resection, which in ...

BRCA1/BARD1 ubiquitinates PCNA in unperturbed conditions to promote continuous DNA synthesis
(Nature Research, 2024-05-20)
Deficiencies in the BRCA1 tumor suppressor gene are the main cause of hereditary breast and ovarian cancer. BRCA1 is involved in the Homologous Recombination DNA repair pathway and, together with BARD1, forms a heterodimer ...

PLK1 Regulates CtIP and DNA2 Interplay in Long-range DNA end Resection.
(Cold Spring Harbor Laboratory Press, 2023)
DNA double-strand break (DSB) repair is initiated by DNA end resection. CtIP acts in short-range resection to stimulate MRE11–RAD50–NBS1 (MRN) to endonucleolytically cleave 5′-terminatedDNAto bypass protein blocks. CtIP ...
