Distinct Types of Regulated Cell Death in Melanoma

Area of Science:

• Oncology
• Cell Biology
• Immunology

Background:

• Resistance to cell death is a key characteristic of cancer, especially in melanoma.
• Abnormalities in cell death regulation are linked to melanoma's malignant progression and resistance to therapy.

Purpose of the Study:

• To systematically review the roles and mechanisms of various regulated cell death (RCD) types in melanoma.
• To explore the potential of targeting RCD pathways for melanoma treatment.

Main Methods:

• Systematic review of literature on RCD in melanoma.
• Analysis of distinct RCD pathways including apoptosis, autophagy, pyroptosis, immunogenic cell death, necroptosis, and ferroptosis.
• Examination of therapeutic strategies targeting RCD.

Main Results:

• Multiple RCD types (apoptosis, autophagy, pyroptosis, immunogenic cell death, necroptosis, ferroptosis) are implicated in melanoma.
• Autophagy can promote melanoma survival but excessive activation leads to cell death.
• Necroptosis and pyroptosis can enhance anti-melanoma immune responses and immunotherapy efficacy.
• Ferroptosis targets specific axes (SLC7A11/GPX4) to overcome melanoma resistance.

Conclusions:

• Regulated cell death pathways play multifaceted roles in melanoma development and treatment.
• Targeting RCD pathways, including ferroptosis and necroptosis, shows significant therapeutic potential for melanoma.
• Developing agents targeting RCD pathways is a promising strategy for melanoma suppression.
