Chromatin spatial analysis by METALoci unveils sex-determining 3D regulatory hubs Nature Structural & Molecular Biology - METALoci, a new three-dimensional genome computational tool, reveals a major rewiring of regulatory interactions during sex determination. By combining...

🚨 We’re happy to announce (finally!) the publication of METALoci, in collaboration with @dariloops.bsky.social and heroes: @jrotwitguez.bsky.social & @imotagom.bsky.social.

METALoci integrates #3DGenome and #Epigenetics data into a unified framework we believe is very useful!

Injury-induced electrochemical coupling triggers organ growth Organ repair and growth rely on coupling tissue-wide membrane depolarization with intracellular proliferative signaling.

New paper alert!🤩Super proud that our story led by superstar postdocs @liujinghui.bsky.social and @nerlielisa.bsky.social is finally out! We found how electrical signals are key for promoting organ regenerative growth!!! A thread 🧵https://www.science.org/doi/10.1126/sciadv.aec0687

Single-molecule dynamics of the TRiC chaperonin system in vivo - Nature Single-particle tracking experiments in intact cells reveal dynamic co- and post-translational interactions of the TRiC–PFD chaperonin complex with client proteins during in vivo protein folding.

I’m excited to share my first-author paper, with co-first author @rongqinxiaoxiao.bsky.social, now out in @nature.com. We developed a live-cell single-particle tracking platform to see how TRiC & prefoldin engage proteins during co- and post-translational folding. 1/9 www.nature.com/articles/s41...

Interphase chromosome conformation is specified by distinct folding programmes inherited through mitotic chromosomes or the cytoplasm - Nature Cell Biology Schooley et al. find that mitotically bookmarked loci drive a transient chromosome folding state during G1 entry that is subsequently modulated by factors inherited through the cytoplasm.

Exciting new paper out! @allanaschooley.bsky.social and Sergey Venev led this project that let to the discovery of two chromosome folding programs: one inherited via mitotic chromosomes and one mitotic inherited through the cytoplasm!

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.

Retroviral insertions contributed to the divergence of human and chimpanzee brains Over the past 5 to 7 million years, humans and chimpanzees have diverged in brain size, structural complexity, and cognitive abilities despite high conservation of protein-coding genes. Notably, the e...

Bah, who needs cohesin if you're at the right place (near). Grover once taught us the difference between near and far (my favourite Sesame Street piece), and now amazing work from @elphegenoralab.bsky.social led by @karissalhansen.bsky.social shows us how: www.science.org/doi/10.1126/...
