Obesity is a major risk factor for over a dozen cancer types, including pancreatic cancer, the third leading cause of cancer-related death in the United States. Despite the rising prevalence of obesity worldwide, surprisingly little is known about how it promotes cancer development. Using animal models that closely mimic human pancreatic cancer, Dr. Muzumdar showed that obesity could provoke abnormal signals sent by the hormone-producing cells of the pancreas to their neighboring tumor-forming cells. With this project, he aims to understand how these hormones are induced and act to drive cancer formation in obesity. Targeting pancreatic hormone signaling could provide a new approach for the prevention and treatment of pancreatic cancer and other obesity-associated cancers.
