Scientists studied a pet gecko that develops cancer naturally. They found genetic changes linked to tumors in this gecko are similar to those in humans. This could help advance cancer research.
A colorful pet gecko, known as the 'lemon frost' morph, has become an important tool for researchers studying how tumors form and spread. This gecko develops aggressive tumors in about 80% of individuals. The study was led by Dr. Ylenia Chiari from the University of Nottingham.
The international research team used whole genome sequencing to compare tumor samples with healthy tissue from the same geckos. They identified a recurring set of genetic changes across the tumors. Many of these altered genes and biological processes have already been linked to cancer in humans and other animals.
Unlike laboratory mice, which often require researchers to artificially trigger tumor growth, lemon frost geckos develop cancer naturally and at a relatively young age. This provides scientists with a rare chance to observe how cancer begins, evolves, and spreads under natural conditions.
Why It Matters
Understanding how cancer develops in animals could lead to new ways of preventing, detecting, and treating cancer in humans. This research highlights the importance of studying a wide range of species to find answers to complex medical questions.
