A variety of pet gecko known as the lemon frost gecko naturally develops aggressive tumors in 80% of individuals. These tumors typically appear at an early age and spread to other parts of the body. This characteristic provides a rare opportunity to study the natural progression of the disease, unlike artificially induced cancer models in laboratory settings.
Researchers conducted genomic analyses by comparing cancerous and healthy tissue samples. The changes they identified overlap with certain genes and biological pathways already known in human cancer. These similarities suggest that geckos could serve as a new model for cancer research.
The study emphasizes how natural resistance or susceptibility to cancer across different species can help uncover fundamental mechanisms of the disease. Researchers highlight that conserving biodiversity is not only ecologically crucial but also medically vital, proposing that common biological strategies be sought across all living organisms.
