In Bio Eats World’s Journal Club episodes, we discuss groundbreaking research articles, why they matter, what new opportunities they present, and how to take these findings from paper to practice. In this episode, Stanford Professor Carolyn Bertozzi and host Lauren Richardson discuss the article “Lysosome-targeting chimaeras for degradation of extracellular proteins” by Steven M. Banik, Kayvon Pedram, Simon Wisnovsky, Green Ahn, Nicholas M. Riley & Carolyn R. Bertozzi, published in Nature 584, 291–297 (2020).
Many diseases are caused by proteins that have gone haywire in some fashion. There could be too much of the protein, it could be mutated, or it could be present in the wrong place or time. So how do you get rid of these problematic proteins? Dr. Bertozzi and her lab developed a class of drugs — or modality — that in essence, tosses the disease-related proteins into the cellular trash can. While there are other drugs that work through targeted protein degradation, the drugs created by the Bertozzi team (called LYTACs) are able to attack a set of critical proteins, some of which have never been touched by any kind of drug before. Our conversation covers how they engineered these new drugs, their benefits, and how they can be further optimized and specialized in the future.
