Regulation and Implementation of Apoptosis in Melanoma Tumor Cells with BRAF, NRAS, and NF1 Gene Mutations

This review explores the molecular mechanisms regulating signaling pathways that may be potentially involved in modulating apoptosis in melanoma tumor cells harboring mutations in BRAF, NRAS, and NF1 genes. The high mortality associated with the aggressive nature of melanoma, its significant metastatic potential, and resistance to existing cancer therapies underscore the relevance of this research topic. One contributing factor to the poor therapeutic prognosis is the altered activity of signaling pathway components that promote the survival of melanoma cells. The increased invasion and metastasis of melanoma cells are linked to mutations in BRAF, NRAS, and NF1 genes. Under conditions of oxidative stress within tumor cells, oxidative modifications occur in proteins that are part of these signaling pathways. Reversibly and irreversibly oxidized proteins, including components of signaling pathways, represent molecular targets for the regulation of apoptosis in melanoma tumor cells. Elucidating the molecular mechanisms underlying the regulation of apoptosis in tumor cells harboring mutations enables the proposal of potential molecular approaches for targeted therapy of melanoma.
