Abstract:
Reactive oxygen species (ROS) are highly bioactive molecules involved not only in tissue physiology but also in the development of different human conditions, including premature aging, cardiovascular pathologies, neurological and neurodegenerative disorders, inflammatory diseases, and cancer. Among the different human tumors, cutaneous melanoma, the most aggressive and lethal form of skin cancer, is undoubtedly one of the most well-known "ROS-driven tumor", of which one of the main causes is represented by ultraviolet (UV) rays' exposure. Although the role of excessive ROS production in melanoma development in pro-tumorigenic cell fate is now well established, little is known about its contribution to the progression of the melanoma metastatic process. Increasing evidence suggests a dual role of ROS in melanoma progression: excessive ROS production may enhance cellular growth and promote therapeutic resistance, but at the same time, it can also have cytotoxic effects on cancer cells, inducing their apoptosis. In this context, the aim of the present work was to focus on the relationship between cell redox state and the signaling pathways directly involved in the metastatic processes. In addition, oxidative or antioxidant therapeutic strategies for metastatic melanoma were also reviewed and discussed.
Insights
Reactive oxygen species (ROS) impact melanoma, with excessive production potentially driving tumor growth or apoptosis. This study explores ROS
Area of Science:
- Oncology
- Biochemistry
- Dermatology
Background:
- Reactive oxygen species (ROS) are key regulators of physiological processes and implicated in various diseases, including cancer.
- Cutaneous melanoma, a highly aggressive skin cancer, is strongly linked to ultraviolet (UV) radiation exposure and excessive ROS production.
- The precise role of ROS in melanoma metastasis remains incompletely understood, with evidence suggesting both pro-tumorigenic and cytotoxic effects.
Purpose of the Study:
- To investigate the intricate relationship between cellular redox state and signaling pathways governing melanoma metastasis.
- To review and discuss the potential of oxidative and antioxidant therapeutic strategies for managing metastatic melanoma.
Main Methods:
- Literature review and analysis of existing research on ROS, melanoma progression, and therapeutic interventions.
- Exploration of signaling pathways influenced by cellular redox balance in the context of melanoma metastasis.
Main Results:
- Excessive ROS production in melanoma can paradoxically promote tumor cell proliferation and therapeutic resistance.
- Conversely, elevated ROS levels can also induce apoptosis in melanoma cells, highlighting a dual role.
- Specific signaling pathways linking redox state to metastatic processes were identified for further investigation.
Conclusions:
- The dual role of ROS in melanoma progression necessitates a nuanced understanding for effective therapeutic targeting.
- Targeting the cellular redox state presents a promising avenue for novel therapeutic strategies against metastatic melanoma.
- Further research is crucial to elucidate the complex interplay between ROS and melanoma metastasis for clinical translation.
