FGFR2 regulates Mre11 expression and double-strand break repair via the MEK-ERK-POU1F1 pathway in breast tumorigenesis.

The association between breast cancer risk and genetic variants of fibroblast growth factor receptor 2 (FGFR2) has been identified and repeatedly confirmed; however, the mechanism underlying FGFR2 in breast tumorigenesis remains obscure. Given that breast tumorigenesis is particularly related to DNA double-strand-break-repair (DSBR), we examined the hypothesis that FGFR2 is involved in DSBR. Ou...

DNA double-strand break repair pathway choice is directed by distinct MRE11 nuclease activities.

MRE11 within the MRE11-RAD50-NBS1 (MRN) complex acts in DNA double-strand break repair (DSBR), detection, and signaling; yet, how its endo- and exonuclease activities regulate DSBR by nonhomologous end-joining (NHEJ) versus homologous recombination (HR) remains enigmatic. Here, we employed structure-based design with a focused chemical library to discover specific MRE11 endo- or exonuclease inh...

Double strand break repair.

DNA double-strand breaks (DSBs) are the most dangerous form of DNA damage and can lead to death, mutation, or malignant transformation. Mammalian cells use three major pathways to repair DSBs: homologous recombination (HR), classical nonhomologous end joining (C-NHEJ), and alternative end joining (A-NHEJ). Cells choose among the pathways by interactions of the pathways with CtIP and 53BP1. HR i...

The role of the Mre11–Rad50–Nbs1 complex in double-strand break repair—facts and myths

Homologous recombination (HR) initiates double-strand break (DSB) repair by digesting 5'-termini at DSBs, the biochemical reaction called DSB resection, during which DSBs are processed by nucleases to generate 3' single-strand DNA. Rad51 recombinase polymerizes along resected DNA, and the resulting Rad51-DNA complex undergoes homology search. Although DSB resection by the Mre11 nuclease plays a...

DNA double-strand break repair pathway choice in Dictyostelium.

DNA double-strand breaks (DSBs) can be repaired by homologous recombination (HR) or non-homologous end joining (NHEJ). The mechanisms that govern whether a DSB is repaired by NHEJ or HR remain unclear. Here, we characterise DSB repair in the amoeba Dictyostelium. HR is the principal pathway responsible for resistance to DSBs during vegetative cell growth, a stage of the life cycle when cells ar...
