- University of Guelph researchers analyzed ~500 cat tumors from five countries, publishing the largest genetic profiling of feline cancers in Science.
- FBXW7 was the most frequently mutated gene in feline mammary tumors, appearing in >50% of cases, mirroring its role in aggressive human breast cancer.
- Cat tumors showed shared driver mutations with dog and human cancers across blood, bone, lung, skin, gastrointestinal, and central nervous system tissues.
- Owners' environments were highlighted as a possible common factor, since cats share the same surroundings as their human companions.
- Chemotherapy agents demonstrated increased efficacy against feline mammary tumors harboring FBXW7 mutations in tissue samples, suggesting a route for targeted treatment.
Why it matters: Veterinary oncologists and pharma firms gain a new genetic database of 500 feline tumors, enabling faster development of targeted therapies that lower treatment costs for pet owners and inform human cancer drug design.
