Congrats @JennKong07, glad to see this out: biorxiv.org/content/10.1101/…. Cool idea to tune development signaling in utero to manage birth defects.

Gene-teratogen interactions influence the penetrance of birth defects by altering Hedgehog signal...

Birth defects result from interactions between genetic and environmental factors, but the mechanisms remain poorly understood. We find that mutations and teratogens interact in predictable ways to...

New preprint on the mechanism of action (MOA) by which oxaliplatin kills cells, from the @RohatgiLab and @Onn_Brandman lab, both @StanfordBiochem! biorxiv.org/content/10.1101/…

Oxaliplatin kills cells via liquid-liquid demixing of nucleoli

Platinum (Pt) compounds such as oxaliplatin are amongst the most commonly prescribed anti-cancer drugs. Despite their considerable clinical impact, the molecular basis of platinum cytotoxicity and...

@RohatgiLab, Arun Radhakrishnan, & Christian Siebold review how the Hedgehog (Hh) receptor PTCH1 uses its transporter-like function to inhibit the GPCR SMO, with cholesterol as a ligand for SMO to effect downstream signaling. go.nature.com/2HduKgI

Woohooo!!! 🥳🎉 Our paper just went online @Dev_Cell! The major fundamental question we sought to address was, what are the mechanisms that regulate a receiving cell’s sensitivity to extracellular morphogens? 🧵🧵🧵 cell.com/developmental-cell/…

We welcome feedback on our characterization of a novel membrane-tethered ubiquitination pathway critical for the proper patterning of multiple tissues during development. In collaboration with the labs of Cecilia Lo, Teresa Gunn, and L. Aravind. biorxiv.org/content/10.1101/…

A ubiquitin-based mechanism for the oligogenic inheritance of heterotaxy and heart defects

The etiology of congenital heart defects (CHDs), amongst the most common human birth defects, is poorly understood partly because of its complex genetic architecture. Here we show that two genes...

Check out this article by Ramin Dubey of the Rohatgi Lab and collaborators just published in eLife! "R-spondins engage heparan sulfate proteoglycans to potentiate WNT signaling" doi.org/10.7554/eLife.54469

R-spondins engage heparan sulfate proteoglycans to potentiate WNT signaling

Heparan Sulfate Proteoglycans function as receptors for the R-spondins, a family of growth factors that amplify the strength of WNT signaling during development and in adult stem cells.

Membrane cholesterol accessibility as the messenger that communicates the hedgehog signal between patched and smoothened. Collaborative work with Arun Radhakrishnan's lab: elifesciences.org/articles/5… #gpcr #cilia #lipids #signaling #developmentalbiology #crispr

Cholesterol accessibility at the ciliary membrane controls hedgehog signaling

The patched hedgehog receptor inhibits the transmembrane transducer smoothened by reducing the accessibility of cholesterol locally at the membrane of the primary cilium.

Nice collaboration with the Siebold lab reveals the deep evolutionary connection between Hedgehog signaling and cholesterol transport-- congratulations to Maia Kinnebrew. Cholesterol is both a substrate and (when coupled to a protein ligand) an inhibitor of Patched!
Nature Chemical Biology@nchembio

Our new paper from @RohatgiLab and Christian Siebold’s group at @NDMOxford used structural and MD analysis to show that cholesterol inhibits Patched by inserting into the extracellular domain. Readable link at rdcu.be/bRIMF. go.nature.com/2kVbwkW
