Cohesin guides homology search during DNA repair using loops and sister chromatid linkages
Accurate repair of DNA double-strand breaks (DSBs) is essential for genome stability, and defective repair underlies diseases such as cancer. Homologous recombination uses an intact homologous sequenc...

1/ out in @science.org! We found a new asymmetry in large-scale chromosome structure: sister chromatids are shifted by hundreds of kb in the 5′→3′ direction of their inherited strands! A close collaboration w/ @gerlichlab.bsky.social , led by @flaviacorsi.bsky.social www.science.org/doi/10.1126/...

Our paper is out in The EMBO Journal @embojournal.org! 🎉 We show how replicated chromosomes can maintain sister chromatid cohesion while still allowing dynamic loop folding within nested hierarchy of TADs. Check it out below 👇 1/2

New preprint out!🧬 How do cells keep replicated sister chromatids linked for DNA repair while folding 3D loops for gene expression? Extrusion folds DNA but separates sisters, while cohesion connects them, risking mutual interference. How do they coexist?🧵👇

81 years after Italy’s Liberation, the lesson remains unchanged: freedom is never guaranteed. Today more than ever before.

Fascism belongs in the past only if we keep it there, through memory, vigilance, and action.

La libertà va difesa ogni giorno.

I am really happy to share this fantastic work by @mfdspicer.bsky.social (and just as honoured to be his desk neighbour!).
A beautiful study showing how DNA fragments are contained in apoptotic cells to prevent their spread. Check it out!
1/New preprint just dropped! 🔥🔥 We investigate how the genome is destroyed in apoptotic cells in a way that prevents DNA fragments from spreading beyond the dying cell 🧬⚰

Done here at @imbavienna.bsky.social & in the super @rcollepardo.bsky.social & Rosen labs:

Very happy to share my postdoc work (on preprint), where we try to understand a long-standing transcription-silencing paradox, and uncovered a hidden RNA decay arm of nuclear piRNA pathway, see detailed threads quoted from @juliusbrennecke.bsky.social
Intrigued by a long-standing conundrum in small RNA biology—how nuclear Argonaute proteins silence transposons when they *need* target transcription for their own recruitment—we studied the piRNA pathway.

And found a hidden RNA-decay axis from Piwi to the RNA exosome.
RNA decay via the nuclear exosome is essential for piwi-mediated transposon silencing https://www.biorxiv.org/content/10.64898/2025.12.16.694471v1
