I'm so excited to share our preprint! We asked a deceptively simple question: how do cationic cell-penetrating peptides (+CPPs) - found in immunity, venoms, and disease actually enter cells? www.biorxiv.org/content/10.6...
biorxiv.org
Lipoproteins modulate the uptake and biological function of cationic cell-penetrating peptides across the animal lineage.
Cationic cell-penetrating peptides (+CPPs) are pervasive killer peptides produced by all animals and found in innate immune systems, venoms and neurodegenerative diseases. Despite their ubiquity, the ...

First preprint from the lab spearheaded by our first grad student @sovannytaylor.bsky.social! We discovered "lipoprotein hitchhiking" as a novel cell penetrance mechanism of killer peptides that has convergently arisen across 600 million years of animal and in human disease. 1/n

1/ Excited to share our new study with @brumbaugh-lab.bsky.social, out in @natbiotech.nature.com! P-bodies selectively sequester RNAs encoding cell fate regulators, often from the preceding developmental stage. Releasing these RNAs can drive changes in cell identity. 🧵 www.nature.com/articles/s41...

Hey #chemsky and beyond, with all that is going on, I am curious what expensive, high margin molecules we could provide to the community for free. What things do you use all the time, cost way too much, and would make a difference? Alexa Fluor 488 NHS? Other dyes? Other molecule?

Is chromatin ordered or disordered? It all depends on the linker DNA length. Check our latest work with Mike Rosen and Sy Redding. We explore how changes in linker DNA length (as small as 1 bp) fine-tune chromatin structure, between order and disorder, and the properties of chromatin droplets
