Rescuing the bacterial replisome at a nick requires recombinational repair and helicase reloading - Nature Communications DNA damage can lead to cell death. Here, the authors show that a simple cut on either strand of DNA can inactivate bacterial chromosome replication. Surprisingly, only a core set of recombination prot...

CIP2A is required for mitotic recruitment of the SLX1/XPF/MUS81 tri-nuclease complex to replication stress-induced DNA lesions to maintain genome integrity Perturbed DNA replication can lead to incompletely replicated DNA when cells enter mitosis and can interfere with chromosome segregation. Cells therefore require mechanisms to resolve these lesions du...

Extremely happy to share that my main PhD project about CIP2A-TOPBP1 and the SMX complex is now available online as pre-print.

Huge thanks to all co-authors but especially @marcelvanvugt.bsky.social for giving me the opportunity to work on this exciting project!

“A CPC-shelterin-BTR axis regulates mitotic telomere deprotection”.

Here we identify the mechanism that unwinds telomere-loops (t-loops) during mitotic arrest to activate the DNA damage response and signal mitotic stress.

WEE1 inhibitors synergise with mRNA translation defects via activation of the kinase GCN2 Inhibitors of the protein kinase WEE1 have emerged as promising agents for cancer therapy. In this study, we uncover synergistic interactions between WEE1 small-molecule inhibitors and defects in mRNA translation, mediated by activation of the integrated stress response (ISR) through the kinase GCN2. Using a pooled CRISPRi screen, we identify GSPT1 and ALKBH8 as factors whose depletion confer hypersensitivity to the WEE1 inhibitor, AZD1775. We demonstrate that this synergy depends on ISR activation, which is induced by the off-target activity of WEE1 inhibitors. Furthermore, PROTAC-based WEE1 inhibitors and molecular glues show reduced or no ISR activation, suggesting potential strategies to minimise off-target toxicity. Our findings reveal that certain WEE1 inhibitors elicit dual toxicity via ISR activation and genotoxic stress, with ISR activation being independent of WEE1 itself or cell-cycle status. This dual mechanism highlights opportunities for combination therapies, such as pairing WEE1 inhibitors with agents targeting the mRNA translation machinery. This study also underscores the need for more precise WEE1 targeting strategies to mitigate off-target effects, with implications for optimising the therapeutic potential of WEE1 inhibitors. ### Competing Interest Statement The authors have declared no competing interest.

in parallel, a study that describes very similar results was posted by the lab of Stephen Jackson from Cambridge UK:

Very nice work! Congrats

The transcriptomic architecture of common cancers reflects synthetic lethal interactions - Nature Genetics Tumor cells upregulate compensatory buffering genes following tumor suppressor loss. These genes may represent new synthetic lethal partners that could be harnessed therapeutically.

We show transcriptomic buffering of tumour suppressor loss via syn. lethal genes is not anecdotal but a cancer hallmark. Buffering also seen in BRCAness, predicts penetrant syn leth effects and outcome. @icr.ac.uk @cancerresearchuk.org @breastcancernow.bsky.social www.nature.com/articles/s41...
