NC State, International Researchers Receive Grant to Examine Why Fido – and His Owner – Get Cancer
Golden retrievers are highly susceptible to cancers arising in the blood, lymphatic and vascular systems. Now, canine cancer scientists at North Carolina State University, the University of Minnesota, the Broad Institute in Massachusetts and Uppsala University in Sweden are teaming up with two animal-health foundations to find out why. Their findings may benefit humans as well because the genes involved in cancer are often the same in dogs and people.
The researchers’ goal is to discover the genes and genetic changes that lead to about one in five golden retrievers getting hemangiosarcoma, a rare, rapidly growing cancer of the cells that form blood vessels, and about one in eight golden retrievers contracting lymphoma, a cancer of a part of the immune system called the lymphatic system. In addition, the scientists will determine why golden retrievers are predisposed to the cancers, how the risk could be reduced, and whether DNA tests could aid in diagnosis and treatment. They will also study the mutations that occur in the tumors and their susceptibility to chemotherapy to identify the treatments most effective against the cancers.
The three scientists leading this project represent some of the top canine cancer researchers in the world. They include Dr. Matthew Breen, professor of genomics at NC State and the Center for Comparative Medicine and Translational Research (CCMTR), and genetics researcher at the University of North Carolina’s Lineberger Comprehensive Cancer Center; Dr. Jaime Modiano, professor of oncology and comparative medicine with the University of Minnesota’s College of Veterinary Medicine and Masonic Cancer Center; and Dr. Kerstin Lindblad-Toh, director of the Vertebrate Genome Biology Program at the Broad Institute, and a professor of comparative genomics at Uppsala University in Sweden.
“Already we have shown that several human and canine cancers share remarkable similarities in their genetic makeup,” Breen says. “This new study provides a ‘golden’ opportunity to accelerate these studies to the next level. Data that emerge from this study should offer new insight into cancer predisposition and progression in dogs, and may have far reaching impact on advancing our understanding of human cancers. Once again, man’s best friend is there for us, right by our side.”
Owners of golden retrievers diagnosed with hemangiosarcoma and lymphoma can support this research by donating a small tumor or blood sample. Blood samples from healthy golden retrievers older than 12 years of age also are needed.

The Center for Comparative Medicine and Translational Research (CCMTR) is a community of more than 100 research scientists from five North Carolina State University colleges. These investigators are involved in collaborative “One Health” studies with government, private and other academic researchers to advance knowledge and practical applications that improve the health and well being of people and animals.
