Beta cell-derived cholecystokinin drives obesity-associated pancreatic adenocarcinoma development
Garcia C, Venkat A, McQuaid D, Agabiti S, Tong A, Mathew B, Cardone R, Starble R, Ruiz C, Zheng C, Sogunro A, Jacox J, Loh K, Kibbey R, Krishnaswamy S, Muzumdar M. Beta cell-derived cholecystokinin drives obesity-associated pancreatic adenocarcinoma development. Nature Communications 2026, 17: 3292. PMID: 41760660, PMCID: PMC13066563, DOI: 10.1038/s41467-026-69821-2.Peer-Reviewed Original ResearchThis study investigates how obesity-induced cholecystokinin (CCK) expression in pancreatic beta cells drives pancreatic cancer development by altering cellular signaling within the environment of arising tumors, suggesting potential therapeutic targets.
