PhD student at Instute of Science Tokyo and @bunsyo.bsky.social Lab, Dept. of Genome Stress Signaling, Japan I'm interested in DNA replication stress and replication fork maintenance mechanism.

Exciting new work from our former super-labmate! x.com/taiiga_bio and @bunsyo.bsky.social revealed an amazing interplay among PrimPol, TLS polymerases, and active fork slowing during oncogenic replication stress. x.com/taiiga_bio/s...

A new paper from B-Lab is out in Nature Communications! We discovered that ATR-regulated PrimPol switches between fork slowing and repriming to help cells tolerate oncogenic KRAS-induced replication stress, promoting survival while limiting error-prone DNA synthesis. www.nature.com/articles/s41...

Is euchromatin really “open”? 🧬 Using super-resolution imaging🔬 our new study @natgenet.nature.com reveals: Euchromatin forms condensed domains in live cells. Cohesin constrains them and prevents domain mixing for proper transcriptional insulation🚧 🔗 www.nature.com/articles/s41... (1/2)

Linker histone H1 is known to bind ssDNA (www.nature.com/articles/s41...), and this study identifies HPF1 as a novel interaction partner of phos-H1 by LLPS assemblies at stressed forks. Interesting new link between linker histones, replication stress, and LLPS. pubs.acs.org/acbcct/artic...

Our latest work describing DDIAS as a new component of the TOPBP1-CIP2A pathway in mitosis and its requirement for brain development is now published. Fantastic collaboration with @fenaochs.bsky.social, @profstewartlab.bsky.social, Lars Allan Larsen, @tcr-miller.bsky.social, Zafar Iqbal & others

New work from the lab! We report that DDIAS is a downstream effector of CIP2A-TOPBP1 in mitosis that suppresses ssDNA to preserve genome integrity. From the great @yiboxue.bsky.social and many collaborators! Free link: authors.elsevier.com/a/1nfiF3vVUP... Pay link: www.cell.com/molecular-ce...

☕Song et al. report that ATM maintains replication fork speed by counteracting chromatin-bound cGAS-induced fork slowing. They show that ATM and ATR phosphorylate MRE11 to release cGAS from chromatin in a process dependent on MRE11 nuclease activity. 👉https://rdcu.be/fkC8i bit.ly/4x6ZtjN

Very interesting result classifying replication stress tolerance mechanism. Replication fork stalling at DNA lesions is driven by competition between damage bypass pathways www.researchsquare.com/article/rs-8...

Replication fork stalling at DNA lesions is driven by competition between damage bypass pathways
Replication fork stalling or slowdown is a hallmark of replication stress and can lead to DNA damage-induced fork collapse and genetic instability. Stalled replication forks must be stabilized to enab...
