Giant KASH proteins and ribosomes establish distinct cytoplasmic biophysical properties in vivo
Living tissues maintain unique intracellular biophysical properties under the control of cytoplasmic constraints and crowding.

Thrilled to share that a big piece of my thesis here in the Starr–Luxton is now out in Science Advances! We discovered that the cytoplasm of living animal tissues is extremely crowded and constrained, maintained by ribosomes and the giant KASH protein ANC-1.

Immune tissue behaves as shapeshifting active living matter as it fights intruders. Using liquid-like multicellular B cell droplets, we show that cytokines control the physical state of immune tissue.

🎉Check out our new preprint!! 🧬We found that lamin mutations in muscular dystrophy don’t just affect the nucleus — they disrupt a nucleolar–ribosomal axis that reorganizes the entire cytoplasm.
Very grateful to @danstarrucdavis.bsky.social, @gwgl.bsky.social and our lab for collaboration & support!

🧬 NEW Starr-Luxton Lab PREPRINT: Our 🌠grad student
@XiangyiDing
figured out why muscular dystrophy mutations cause such widespread cellular chaos. The answer wasn't what we expected - and it changes how we think about the disease. Thread🧵 (1/6). www.biorxiv.org/content/10.1...

🧬BREAKING!🪱Plot twist: Cells aren't meditation pools, they're overcrowded concerts with VIP ropes everywhere! Our
study reveals worm cells are insanely crowded AND compartmentalized. Ribosomes = packing peanuts, ANC-1 = the bouncer!

It was great to gave a plenary talk to the worm community 🪱 Received great questions and comments. Thanks to both of my PIs @gwgl.bsky.social and @danstarrucdavis.bsky.social for the co-mentorship and thanks to the organizers @genetics-gsa for bringing us together.
Amazing talk (and videos) in plenary 2 from Xiangyi Ding ( @danstarrucdavis.bsky.social ) about biophys constraints in cytoplasm. #Celegans cytoplasm is more like jelly than honey (human cells), plus found gene that constrains this mess particle diffusion. #worm25
