Abstract:
Melanoma is a highly aggressive tumor and almost always fatal when metastatic. Herein, we discuss recent findings on the mechanisms of resistance of human cutaneous melanoma. To achieve a precision medicine approach, the heterogeneity and plasticity of tumor cells are two crucial aspects to be investigated in depth. In fact, to understand the mechanisms that cells use to acquire a resistant phenotype after chemotherapy or how resistant cells inside the tumor are selected, it is the most important issue for a successful therapy. Since new therapeutic strategies are trying to go in this direction, we discuss here the state of the art of the research and the clinical impact of these strategies. We also discuss and suggest future research directions to develop approaches able to define the best concentration and time of exposure of the drug or the cocktails of drugs for each specific patient based on his/her biological features.
Insights
Understanding melanoma resistance mechanisms is key for effective cancer therapy. Research focuses on tumor cell heterogeneity and plasticity to develop personalized treatment strategies against this aggressive cancer.
Area of Science:
- Oncology
- Cancer Biology
- Dermatology
Background:
- Melanoma is an aggressive skin cancer with a poor prognosis when metastatic.
- Therapeutic resistance significantly limits treatment efficacy in melanoma patients.
- Tumor cell heterogeneity and plasticity are critical factors in melanoma progression and treatment failure.
Purpose of the Study:
- To review current knowledge on the mechanisms of therapeutic resistance in human cutaneous melanoma.
- To highlight the importance of tumor cell heterogeneity and plasticity for precision medicine in melanoma.
- To discuss emerging therapeutic strategies and future research directions for overcoming melanoma resistance.
Main Methods:
- Review of recent scientific literature on melanoma resistance mechanisms.
- Analysis of the role of tumor cell heterogeneity and plasticity in treatment response.
- Discussion of current and future therapeutic strategies for overcoming resistance.
Main Results:
- Melanoma cells develop resistance through various mechanisms, often involving tumor cell plasticity.
- Heterogeneity within melanoma tumors contributes to the selection of resistant cell populations.
- Understanding these mechanisms is crucial for developing effective, personalized treatment approaches.
Conclusions:
- Addressing melanoma heterogeneity and plasticity is essential for advancing precision medicine.
- New therapeutic strategies are being developed to target resistance mechanisms.
- Future research should focus on patient-specific biological features to optimize drug concentration and exposure time.

Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
