Abstract:
Melanoma is a major problem for many individuals worldwide. Although no effective treatment is available, promising new strategies are being developed. A better understanding of the inner workings of the disease would undoubtedly lead to improved treatments. Mouse melanoma models have been used to elucidate many key regulatory pathways involved in melanoma initiation and progression, and models with mutations in the oncogenes RAF and RAS have been particularly informative. Here, we summarize and evaluate the human relevance of various RAF and RAS mouse melanoma models and their contribution to our understanding of melanoma.
Insights
Mouse models with RAF and RAS mutations offer valuable insights into melanoma development. Evaluating their human relevance aids in understanding this complex skin cancer and developing new treatments.

- Mouse models are crucial for studying melanoma initiation and progression.
Purpose of the Study:
- To review and assess the human relevance of RAF and RAS mouse melanoma models.
- To evaluate the contribution of these models to understanding melanoma biology.
Main Methods:
- Literature review and critical analysis of existing RAF and RAS mouse melanoma models.
- Evaluation of model systems based on their fidelity to human melanoma genetics and pathology.
Main Results:
- RAF and RAS mouse melanoma models have significantly advanced the understanding of key regulatory pathways.
- Specific models demonstrate varying degrees of relevance to human melanoma, particularly concerning oncogenic mutations.
- These models have been instrumental in identifying potential therapeutic targets.
Conclusions:
