Autophagy in the Tumor or in the Host: Which Plays a Greater Supportive Role?

Abstract

<b/> Autophagy has been identified as a potential therapeutic target in pancreatic ductal adenocarcinoma, one of the most lethal cancers, with few therapeutic options. Yang and colleagues successfully created a genetically engineered mouse model focused on the autophagy gene Atg4b that allows the study of therapeutic autophagy inhibition in fully formed tumors. Using this tool, they demonstrated that selective autophagy inhibition in either the tumor cells, normal host cells, or both suppresses tumor growth.
