Huge congrats to the entire team, super cool work!
Alex de Mendoza@alexdemendoza.bsky.social · 2mo agoCapolavoro 🎨 alert 🚨! What is the role of gene body methylation in invertebrates? Despite extensive speculation linking it to plasticity and environmental responses, its mechanistic effects and heritability remain unclear.

Gene body methylation suppresses intragenic transcription and permits epigenetic inheritance in a cnidarian - Nature Ecology & Evolution
Experiments in the cnidarian Nematostella vectensis show a role of gene body methylation in transposable element suppression and that epigenetic inheritance is constrained by chromatin context and tra...

Our preprint on the 'Origins of Eukaryotic Metabolism' is out! Take a look at some of the new findings on the origin of eukaryotic membranes, metabolic integrations between archaeal and bacterial ancestors, and other fascinating prokaryotic interactions during eukaryogenesis. doi.org/10.64898/202...

Even more bizarrely, some retrotransposons encode DAMs, but also cytosine DNMTs and Chromo (histone reader) domains, we dub these guys EpiLTRs. Why on earth a TE needs a more complex epigenome than many classic eukaryotic model species (e.g. yeast or flies) boggles us, but hard to explore yet. 5/
New preprint! In an fun collaboration with @imaeso.bsky.social and @mirimiam.bsky.social led by Manu F-M, we set to explore the potential adaptation of transposable elements 👾 to host adenine DNA methylation by recruiting prokaryotic DAM methyltransferases: www.biorxiv.org/content/10.6.... 1/6

Thrilled to be part of this extraordinary set of groups of the #EvoDevOmics Network, and glad to see the interactions of my team with members of other labs. Great presentations by @alfonso233.bsky.social and @baielx.bsky.social of our lab projects on gene loss and genomics. #dissemination #outreach
Isabel Almudi@isabelalmudi.bsky.social · 3mo agoExhausted but extremely happy for the two past days of very exciting Science! The EvoDevOmics Spanish Network gathered together in BCN to discuss about evodevo & omics, lots of great talks, discussions and future collaborations. 🤩 #evodevo

Amazing couple of days enjoying & discussing science in the best possible company during the Barcelona meeting of the 'EvoDevOmics Network', funded by @ageinves.bsky.social. Really happy to see how the EvoDevo community in Spain is thriving & fostering a fantastic new generation of PhDs & Postdocs.
& the rest of labs for such fantastic network: @anariesgo.bsky.social, @evodevogenomeub.bsky.social, @patrialvarezcam.bsky.social, @phylobrain.bsky.social, @fany-real.bsky.social, @multicellgenome.bsky.social,@obog.bsky.social, @arnausebe.bsky.social, @bpernaute.bsky.social, Almuedo & Flames labs
Special thanks to @mirimiam.bsky.social @melisupf.bsky.social, @jpascualanaya.bsky.social, and @imaeso.bsky.social @irbio-ub.bsky.social @geneticsub.bsky.social for organising!

🚨🧬🚨 We're looking for a specialized Research Assistant to spearhead a project aimed at exploring new RNA therapeutics in diabetes and other metabolic disorders. Junior or Senior, we're hoping to recruit a highly motivated and self-driven scientist interested in both basic and applied science. 🦄
New preprint!! 🚨 Did you know that many vertebrate species determine sex based on environmental conditions rather than chromosomes? Some turtles, like Trachemys scripta, rely on temperature. We learned more about how this happen molecularly.👇 www.biorxiv.org/content/10.6...

Huge congrats Rafa!!

🚨 1/ Preprint Alert! Sex determination outcome is conserved across vertebrates (i.e. generating 2 compatible sexes) ♀️♂️ But are the cell types and gene programs behind them conserved too? 🧬 Spoiler: not really 👀 Find out in our new preprint ⬇️ www.biorxiv.org/content/10.6...
