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...

A great collaboration between Elly Tanaka and Miguel Torres labs.

We’re happy to share our new work in which we ask how axolotls regenerate their hearts and could they help mammals with that?

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
