📢 New work with @gonzalezlabbcn.bsky.social out now in Molecular Biology and Evolution!
Transgenerational effects of heat shock 🥵 on gene regulation 🧬 and fitness-related traits in natural Drosophila 🪰 populations: academic.oup.com/mbe/article/...
Very upsetting to hear the sad news of Greg Hannon’s passing. I always enjoyed our far too few conversations we had over the years. He had an interesting and insightful perspective on any science being discussed. He will be missed. www.cruk.cam.ac.uk/news/in-memo...
New preprint from us and @emiliapsantos.bsky.social’s #NERC grant, led by Jake Morris, @gadusmo.bsky.social et al
Using an interspecific cross between two #cichlids to think about models of #brainevolution 🐟🧠
Feedback and suggestions welcome! 🙏🏻

Germ cells have their own versions of core transcription factors and fertility depends on them.
We're hiring a PhD student to figure out how! 📢
Fly genetics + proteomics + genomics. Fully funded.

Deadline May 1 👇
Please share with anyone who might be interested!
We are looking for a Postdoc to join our lab at @oxfordbiochemistry.bsky.social. This is a dry-lab focused post on the computational analysis of long read single-cell sequencing data to understand the role of transposable elements (TEs) in early development. my.corehr.com/pls/uoxrecru... #TEsky
There is accumulating evidence that sperm miRNAs function to regulate embryonic gene expression and transmit inherited phenotypes to offspring but how does this work since sperm cargo is massively diluted in the egg upon fertilization. Here we directly address this ? www.biorxiv.org/content/10.6...
#TEsky Another paper in our TE ecology exploration of the Octopus out in BioEssays. Types of niches for TEs and what that could mean for their expression in neural tissue doi.org/10.1002/bies...
Today the EMBO Journal special issue on molecular ecology and evolution is finally published.
It was a pleasure coordinating this collection together with @berndpulverer.bsky.social and many outstanding authors.

🔥Fantastic paper!🔥
TE with a role in vegetative phase change and gametogenesis, mediated by 24-nt siRNAs acting in trans to a wide range of genes. Found by GWAS in A. thaliana 🌱. Congratulations to the authors! 👏🏻👏🏻👏🏻

So excited to share this manuscript led by the inimitable Cara Brand, who discovered that Topoisomerase II evolution causes hybrid female lethality in Drosophila.
Congrats to Cara, @nickbr0wn.bsky.social, Anirban, and

Our paper is now out in Nature:
“Ancient co-option of LTR retrotransposons as yeast centromeres”
www.nature.com/articles/s41...
A short thread on how retrotransposons helped give rise to yeast point centromeres.

How does the piRNA pathway solve the self vs. non-self problem? 🧬
Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)
Congrats to talented graduate student Aaron Lemus for leading this litterature review on #transposons and #epigenetic remodeling with #aging! @uscleonarddavis.bsky.social
New preprint from the lab! We dig into the regulatory roles of TEs in the mouse placenta, with some surprising findings. Led by the awesome @smamante.bsky.social. Particular kudos to him for navigating the many twists and turns of the project.
Today, we're sharing an open letter from our Chief Executive, Professor Sir Ian Chapman, outlining changes to UKRI investment approach, and addressing concerns about research funding and the financial position of STFC. Read his letter here: www.ukri.org/news/open-le...
Huge congratulations to @juancruedas.bsky.social for successfully passing his PhD viva with minor corrections yesterday! 🧬We’re incredibly proud of you! And even more exciting, the manuscript is on the way. Stay tuned! 👏🥳
@cambiochem.bsky.social
One protein. One pathway. A whole germline fate.
New paper from my postdoc @mpi-bio-fml.bsky.social out in PNAS:
Germline fate determination by a single ARGONAUTE protein in Ectocarpus www.pnas.org/doi/10.1073/...
It is finally out! If you are interested in TE-derived CREs, and newly described, but evolutionary old KZFP-TE mechanistic modalities, read it at www.cell.com/cell-reports....
Thankful to everyone who took part in this work, namely @orpsf.bsky.social and other @trono-lab.bsky.social members. 🫀🧬✨
Crushed to hear of Mark Batzer’s passing. He was the Boyd Professor at Louisiana State University. His influential research revealed how mobile elements shape the genomes of humans & other mammals. Mark’s personality, generosity & positivity were larger than life. He lifted everyone up. HUGE loss 💔
We had a great time at the @cambiochem.bsky.social Away Days, learning about the exciting research across the Department! It was a pleasure to share some of our group’s projects thanks to @migueldvalmeida.bsky.social and @ecwalsh.bsky.social . All set for a year full of science! Stay tuned!
Interested in the unexpected? How about a link between piRNAs and maternal histone mRNAs … Great collab with @sebastianfalk.bsky.social, @koenig-lab.bsky.social and Florian Steiner.

New Year, New Paper!🎊

Centerpiece of Jason Chobirko's PhD, talented PhD student co-mentored by Andrew Grimson & me. Really excited about it!🧵
Very happy to see this preprint out! 🎉 This was the last project I started during my time in the Ketting lab, which was later picked up by Shamitha, who did an amazing job extending our initial observations on C. elegans GTSF-1 to other nematodes + further insights into RdRP interaction.
Happy to share two BioRxiv manuscripts from our lab. One on genetic Argonaute interaction and unexpected non-correlation between small RNAs and their targets:
doi.org/10.64898/202...
The second on IDR processing and IDR-mediated Argonaute loading control:
doi.org/10.64898/202...
Merry Xmas😊
☕Earl Grey v7.0.0 brewed fresh☕
Nested TEs finally get the treatment they deserve: iterative detection of deep nesting, cleaner GFF annotations, and coverage stats that don’t double-count genomic space + a RepeatCraft edge-case fix.
Happy new year to the TE folks! 🧬

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.
