Deep conservation of cis-regulatory elements and chromatin organization in echinoderms uncover ancestral regulatory features of animal genomes
Nature Ecology & Evolution - Analysis of the 3D chromatin architecture and cis-regulatory elements in a sea urchin and a sea star reveals mechanisms of 3D chromatin organization in echinoderms...

Our work on the evolution of the regulatory genome of echinoderms is now out in @natecoevo.nature.com. Led by my former PhD Marta Magri, Danila Voronov & Saoirse Foley. Great collaboration of Arnone, Hinman & Maeso labs, started long time ago with our missed José Luis Gomez-Skarmeta: rdcu.be/eXX8l

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.👇

🚨 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 👀

Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history
Sponges have a cryptic Ediacaran history because ancestral sponges were soft-bodied and had low fossilization potential.
