Polar chromosomes are rescued from missegregation by spindle elongation-driven microtubule pivoting - Nature Communications Polar chromosomes in human cells are prone to late alignment and segregation errors. Here, the authors show that spindle elongation rescues them by repositioning astral microtubules via a pivoting mec...

Your cells divided thousands of times today. Most chromosomes landed where they should, but some got stuck.
New #RBI research reveals how cells rescue trapped chromosomes during division, and why cancer cells often fail at it.

New work from my lab, together with Boris Maček's lab! Using magnetic levitation, we made multicellular spheroids to ask a simple question: how different is mitosis in 3D structures compared with standard 2D monolayers? www.biorxiv.org/content/10.6...

Ad for a postdoc position in centromere biology with colorful chromosomes and centromeres made out of FIMO.

🧪 My lab has an opening for a postdoc position soon! Please share/get in touch!

Mitosis has a timing system. If chromosomes attach properly, cells divide on schedule and keep proliferating. If attachment is slow or incomplete, the delay is recorded — and daughter cells stop dividing.
We explore this link in our new preprint.

PhD position in my lab!

PAF15–PCNA exhaustion governs the strand-specific control of DNA replication Nature - PCNA–PAF15 has a key role in determining replisome dynamics during genome replication and protecting against genome instability.

Dear Colleagues,

Delighted to share that our first lab paper is now published in Nature.!!! 😊😊😊

We identify a previously concealed “safety limit” in DNA replication program: cells intrinsically rate-limit PCNA via PAF15, shaping strand-specific and global replication dynamics.

New preprint from the lab 🎉: γ-tubulin is a novel target of the tubulin autoregulation pathway! Previously thought to exclusively target α- and β-tubulin mRNAs, we show that the TTC5–SCAPER–CNOT11 axis also degrades γ-tubulin mRNA, expanding the scope of this fundamental regulatory mechanism.
