    Insights into RAS-driven melanoma and its therapeutic implications. (PubMed, Cancer Treat Rev)
    Ongoing combination strategies include MEK inhibition with type II RAF inhibitors (naporafenib plus trametinib in phase III trial), ERK1/2 or ERK5 inhibitors, PI3K/mTOR pathway blockade, or CDK4/6 inhibition. Additional investigational approaches include mutation-specific RAS inhibitors (G12C inhibitors already approved for other cancers), NRAS-specific or pan-RAS inhibitors (daraxonrasib in phase III trial for other cancers), targeted protein degradation, RAS-directed peptide and mRNA vaccines (mRNA-4157). NRAS Q61K-derived neoepitopes bound to HLA-A*01:01 have been recognized as immunogenic, suggesting that mutation-specific immunotherapies could represent a promising future strategy. In conclusion, the advent of promising and emerging therapies is set to transform the management of RAS-driven melanoma, making a personalized, biomarker-informed treatment strategy essential for optimizing patient outcomes.

    Targeting the MAPK Pathway for NRAS Mutant Melanoma: From Mechanism to Clinic. (PubMed, Br J Dermatol)
    In recent years, significant clinical advancements have been achieved by targeting the NRAS-MAPK pathway, with novel therapies such as the MEK inhibitor tunlametinib and the combination therapy of the pan-RAF inhibitor naporafenib with trametinib leading the way. In this review, we will systematically summarize the recent advances in the direct targeting of mutant NRAS proteins and their downstream RAF and MEK proteins, as well as targeting the MAPK pathway in combination with other therapeutic targets, including the immunotherapy, to treat NRAS mutant melanoma. Additionally, we will further discuss the current issues and emerging countermeasures related to targeted therapy for NRAS mutant melanoma.
