The F‐box and WD repeat domain containing 7 (FBXW7) tumour suppressor gene encodes a substrate‐recognition subunit of Skp, cullin, F‐box (SCF)‐containing complexes. The tumour‐suppressive role of FBXW7 is ascribed to its ability to drive ub

The DNA damage response (DDR) represents a complex network of proteins which detect and repair DNA damage, thereby maintaining the integrity of the genome and preventing the transmission of mutations and rearranged chromosomes to daughter cells. Faul

Summary: The PSMC3IP-MND1 heterodimer promotes meiotic D loop formation before DNA strand exchange. In genome-scale CRISPR-Cas9 mutagenesis and interference screens in mitotic cells, depletion of PSMC3IP or MND1 causes sensitivity to poly (ADP-Ribose

Bajrami, Walker et al. investigated the synthetic lethality between BRCA gene defects and inhibition of two sirtuin genes, SIRT1 or SIRT6, which was found to be associated with replication stress and increased PARylation. The authors demonstrated tha

Polθ has been recently identified as a therapeutic target in cancer but specific inhibitors are currently unavailable. Here, the authors identify small molecule inhibitors of Polθ’s polymerase activity which elicit BRCA1/2 synthetic lethality, en

PARP inhibitors (PARPi) have been demonstrated to exhibit profound anti-tumour activity in individuals whose cancers have a defect in the homologous recombination DNA repair pathway. Here, we describe the current consensus as to how PARPi work and ho

Abstract Development of resistance to platinum and poly(ADP‐ribose) polymerase inhibitors via secondary BRCA gene mutations that restore functional homologous recombination has been observed in a number of cancer types. Here we report a case of som

The mechanisms of PARP inhibitor (PARPi) resistance are poorly understood. Here the authors employ a CRISPR mutagenesis approach to identify PARP1 mutants causing PARPi resistance and find that PARP1 mutations are tolerated in BRCA1 mutated cells, su

Poly ADP-ribosylation (PARylation) is a highly dynamic post-translation protein modification, but most methods only detect stable PARylation events. Here the authors develop a split-GFP-based sensor for PARylation detection in live cells and use it t

HORMAD1 expression is usually restricted to germline cells, but it becomes mis-expressed in epithelial cells in ~60% of triple-negative breast cancers (TNBCs), where it is associated with elevated genomic instability (1). HORMAD1 expression in TNBC i
