NRAS mutations are found in about 30% of melanoma, a dangerous type of skin cancer. Although recent advancements in melanoma treatments have helped many patients, those with NRAS-mutant melanoma still face challenges. Available treatments for these patients are often not effective, and their cancer can quickly become resistant to treatment. Recently, scientists have developed new drugs called pan-RAS inhibitors that can directly target the NRAS mutations responsible for tumor growth. These drugs have the potential to greatly improve treatment for people with NRAS-mutant melanoma, but we need to learn more about potential resistance to these new drugs. This knowledge will help us develop better treatments for this type of cancer. Studying drug resistance is difficult because tumor can be very different from one another. To overcome these challenges, our study uses advanced technology to observe how individual melanoma cells grow and change. Our approach allows us to monitor the rare cells that adapt to the new pan-RAS inhibitors, helping us understand why some cells become resistant. We will also compare the genes in these adapting cells to those in cells that do not adapt to determine what makes them different. By learning how NRAS-mutant melanoma cells adapt to new treatments, we can design better therapies for patients with this type of cancer. This will help us meet the needs of people with limited treatment options and improve their chances of recovery. Our research aims to move the body of knowledge forward, positively impacting cancer patients and cancer research.
