Genomic analysis of nearly 500 cat tumours reveals shared cancer-driving genes with humans and dogs

Researchers have published a study genetically characterising tumours from approximately 500 cats sourced internationally, identifying shared somatic cancer-driving alterations across domestic cats, dogs and humans. The work, reported via ScienceDaily, found conserved mutations in genes associated with aggressive human cancers, including those linked to aggressive breast cancer subtypes.

Comparative oncology — the study of naturally occurring cancers in companion animals — has a long history as a route to understanding cancer biology, given that cats and dogs develop many of the same tumour types as humans under similar environmental exposures and without experimental induction. Cataloguing the somatic genomic landscape of feline cancers at this scale provides a reference dataset for cross-species comparisons and may help researchers identify cancer-driving genes whose role is conserved across mammalian lineages.
