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

We watched piRNAs and transposons across development, saw them dance tightly and wrote a paper about it.

It's so cool to see it online and we will make a thread about it all very soon. Stay tuned :-)

Full deletion of all introns in yeast was actually my project in the Staley lab, *20 years ago*. I actually found a bunch of phenotypes. We did this in collaboration with the Guthrie lab.
