Feline cancer genetics show strong similarities to human tumors

The short version

• Researchers analyzed tumor samples from nearly 500 domestic cats across five countries, identifying driver mutations that closely mirror those found in human cancers.[ScienceDaily]
• More than half of feline mammary tumors harbored mutations in the FBXW7 gene, a marker also linked to poor prognoses in human breast cancer.[ScienceDaily]
• The team established a freely accessible database to help doctors and veterinarians develop targeted precision oncology therapies.[ScienceDaily]
• While certain chemotherapies showed higher efficacy against mutated tumor samples in vitro, therapeutic success in living animals and humans remains unproven.[ScienceDaily]

Key facts

• Scientists analyzed tumor samples from nearly 500 domestic cats across five countries in a study published in Science.[ScienceDaily]
• The FBXW7 driver gene was mutated in over 50 percent of feline mammary tumors, mirroring a genetic alteration associated with worse human breast cancer outcomes.[ScienceDaily]
• Cross-species genetic parallels were also identified in cancers affecting the blood, bones, lungs, skin, digestive tract, and central nervous system.[ScienceDaily]
• Researchers established a publicly accessible database of feline cancer genetics to advance precision oncology research.[ScienceDaily]
