-- Today, we are thrilled to recognize Mathieu Desaunay, PhD and his mentor Poulikos Poulikakos, PhD of Icahn School of Medicine at Mount Sinai, recipient of the MRF Career Development Award.
Dr. Desaunay's research project entitled, "Next-Generation RAF Targeting Strategies for RAS-Mutant Melanoma", focuses on developing targeted therapies for NRAS-mutant melanoma.
Regarding his work and its potential patient impact, Dr. Desaunay shares:
"Melanoma is an aggressive form of skin cancer that commonly depends on the MAPK pathway (a signaling cascade involving RAS → RAF → MEK → ERK activation). In melanoma, MAPK signaling becomes deregulated and promotes tumor progression. This deregulation is often driven by mutations in RAS, which occur in around 20% of melanoma patients and make the disease particularly difficult to treat with current therapies. Most existing drugs that target the MAPK pathway in RAS mutant melanoma, including RAS, RAF, and MEK inhibitors, act by broadly shutting down this signaling in both cancerous and healthy cells. While this approach can slow tumor growth, it often leads to significant side effects, limited long term effectiveness, and the rapid development of drug resistance.
To overcome these limitations, our research takes a different approach by developing next generation RAF inhibitors that behave in an unexpected way. With the support of the MRF Career Development Award, I aim to uncover the molecular mechanisms behind this paradoxical drug behavior and advance more effective combination therapies, offering new hope for patients with melanoma."
