Immunohistochemical assessment of Pax8 expression during pancreatic islet development and in human neuroendocrine tumors
(Springer Verlag, 2011)
The paired box transcription factor Pax8 is critical for development of the eye, thyroid gland as well as the urinary and reproductive organs. In adult, Pax8 overexpression is associated with kidney, ovarian and thyroid ...

Break-induced RNA–DNA hybrids (BIRDHs) in homologous recombination: friend or foe?
(Wiley-Blackwell, 2023)
Double-strand breaks (DSBs) are the most harmful DNA lesions, with a strong impact on cell proliferation and genome integrity. Depending on cell cycle stage, DSBs are preferentially repaired by non-homologous end joining ...

The chromatin network helps prevent cancer-associated mutagenesis at transcription-replication conflicts
(Nature Research, 2023)
Genome instability is a feature of cancer cells, transcription being an important source of DNA damage. This is in large part associated with R-loops, which hamper replication, especially at head-on transcription-replication ...

Topoisomerase 1-dependent R-loop deficiency drives accelerated replication and genomic instability
(Elsevier, 2022)
DNA replication is a complex process tightly regulated to ensure faithful genome duplication, and its perturbation leads to DNA damage and genomic instability. Replication stress is commonly associated with slow and stalled ...

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 ...

ATRX-Deficient High-Grade Glioma Cells Exhibit Increased Sensitivity to RTK and PDGFR Inhibitors
(MDPI, 2022)
High-grade glioma, including anaplastic astrocytoma and glioblastoma (GBM) patients, have a poor prognosis due to the lack of effective treatments. Therefore, the development of new therapeutic strategies to treat these ...

DDX47, MeCP2, and other functionally heterogeneous factors protect cells from harmful R loops
(Elsevier, 2023)
Unscheduled R loops can be a source of genome instability, a hallmark of cancer cells. Although targeted proteomic approaches and cellular analysis of specific mutants have uncovered factors potentially involved in R-loop ...

XRCC1 Prevents Replication Fork Instability during Misincorporation of the DNA Demethylation Bases 5-Hydroxymethyl-2′-Deoxycytidine and 5-Hydroxymethyl-2′-Deoxyuridine
(MDPI, 2022)
Whilst avoidance of chemical modifications of DNA bases is essential to maintain genome stability, during evolution eukaryotic cells have evolved a chemically reversible modification of the cytosine base. These dynamic ...

The Rad50 coiled-coil domain is indispensable for Mre11 complex functions
(Nature Publishing Group, 2011)
The Mre11 complex (Mre11, Rad50 and Xrs2 in Saccharomyces cerevisiae) influences diverse functions in the DNA damage response. The complex comprises the globular DNA-binding domain and the Rad50 hook domain, which are ...

Zim17/Tim15 links mitochondrial iron–sulfur cluster biosynthesis to nuclear genome stability
(Oxford University Press, 2011)
Genomic instability is related to a wide-range of human diseases. Here, we show that mitochondrial iron–sulfur cluster biosynthesis is important for the maintenance of nuclear genome stability in Saccharomyces cerevisiae. ...
