LA JOLLA\u2014Scientists at the Salk Institute and Vanderbilt University School of Medicine Basic Sciences have found that cells in the pancreas form new cell types to mitigate injury, but are then susceptible to cancerous mutations. The research, led by Salk Professor Geoffrey Wahl<\/a> and Vanderbilt Assistant Professor Kathy DelGiorno<\/a>, former staff scientist in the Wahl lab, was published in the journal Gastroenterology<\/em><\/a> on October 22, 2021.<\/p>\n

The findings establish a \u201cbetter understanding of the mechanisms of healing in the pancreas and when these processes go awry,\u201d says DelGiorno.<\/p>\n

The team used a multidisciplinary approach that combined RNA sequencing, imaging techniques, genetically engineered models and human samples to identify the cell types that form in response to pancreatic injury. From this approach, \u201cwe compared our dataset to published datasets of gastric injury, oncogene-induced pancreatic neoplasia, and human pancreatitis to identify conserved processes across species and organ systems,\u201d says DelGiorno.<\/p>\n

The findings of this paper \u201csupport our long-held thesis that tissue inflammation causes cells to reprogram to a more primitive, developmentally plastic state that under normal circumstances contributes to tissue repair. When subverted by oncogenes like RAS in pancreas cancer, it causes one of the most incalcitrant cancers known to medical science,\u201d says Wahl, holder of the Daniel and Martina Lewis Chair.<\/p>\n

Pancreatic cancer is a major public health burden and is slated to become the second-leading cause of cancer-related deaths in the United States by the year 2030. Currently, the average five-year survival rate for pancreatic cancer is only 10 percent, one of the worst of any cancer type. New and innovative treatments are greatly needed to change these outcomes for pancreatic cancer patients.<\/p>\n

\u201cOur work captured how these acinar cells change in response to injury with incredible resolution. We\u2019ve been able to identify multiple diverse cells generated by the acinar cells and uncover where they came from. Our findings provide a valuable resource to the field of pancreatic cancer research for understanding the processes that happen early in pancreas injury and tumorigenesis,\u201d says first author Zhibo Ma, postdoctoral fellow in the Wahl lab.<\/p>\n

\u201cWe hope to co-opt and\/or target these processes for the benefit of patients needing treatment for pancreatitis and cancer,\u201d says DelGiorno. The Vanderbilt team has received a National Institute of General Medical Sciences Maximizing Investigators’ Research Award to follow up on this work. \u201cWe will be using genetically engineered models to study the lineage trajectories and functional role of the cell types identified in this study,\u201d says DelGiorno. \u201cWe will identify the physiological role of these cell types in pancreatic injury, regeneration, and tumorigenesis.\u201d\u00a0<\/strong><\/p>\n
