Atlas of lysosomal aging reveals a metabolite signature shared with lysosomal storage disorders

Lysosomal dysfunction is a well-recognized feature of aging. Here, we used a suite of tools for rapid lysosomal isolation to construct a multitissue atlas of the metabolite changes lysosomes undergo d...

New preprint 📢 Thrilled to share our long-awaited work on the role of RSX in marsupial X-inactivation. This was a huge team effort over the years, led by @aureliencourtois.bsky.social @sermenchero.bsky.social Sugako Ogushi and Waz Varsally, that allowed us to set up genome editing in opossum embryos

Genome editing of marsupial RSX reveals conserved and divergent principles in mammalian X-inactivation

X-chromosome inactivation balances X-gene dosage between the sexes in eutherians and marsupials. The lncRNA Xist mediates X-inactivation in eutherians but is absent from marsupials. An evolutionarily ...

Pyrenoid tubules are essential for supercharging CO₂ fixation, but they're hard to resolve by microscopy. So, we physically expanded cells to see where different proteins go (3 examples below). The central tubule region appears specialized for CO₂ delivery! www.biorxiv.org/content/10.6...

🚨 New in @natmicrobiol.nature.com! We reveal how the antibiotic target PBP1b fortifies the E.coli division site against osmotic rupture.

The penicillin-binding protein PBP1b fortifies the Escherichia coli division site against osmotic rupture - Nature Microbiology

A specific isoform of PBP1b functions independently of the activator protein, LpoB, to drive generation of a wedge-like peptidoglycan structure that strengthens the division site in Escherichia coli.

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...
