Abstract
Activation of the YAP-TEAD transcriptional complex drives the growth of several cancer types and is a key resistance mechanism to targeted therapies. Accordingly, a host of pharmacological inhibitors to TEAD family paralogs have been developed, yet little is known as to the resistance mechanisms that might arise against this emerging therapeutic class. Here, we report that genetic augmentation of de novo coenzyme A biosynthesis desensitizes YAP-dependent cancer cells to treatment with TEAD inhibitors, an effect driven by increased levels of palmitoyl-CoA that outcompete drug for engagement of the lipid-binding pocket. This work uncovers a potential therapeutic resistance mechanism to TEAD palmitoylation site inhibition with implications for future combinatorial treatments in the clinic.
期刊介绍：
ACS Chemical Biology provides an international forum for the rapid communication of research that broadly embraces the interface between chemistry and biology.
The journal also serves as a forum to facilitate the communication between biologists and chemists that will translate into new research opportunities and discoveries. Results will be published in which molecular reasoning has been used to probe questions through in vitro investigations, cell biological methods, or organismic studies.
We welcome mechanistic studies on proteins, nucleic acids, sugars, lipids, and nonbiological polymers. The journal serves a large scientific community, exploring cellular function from both chemical and biological perspectives. It is understood that submitted work is based upon original results and has not been published previously.
