ROS Pleiotropy in Melanoma and Local Therapy with Physical Modalities

Area of Science:

• Biochemistry
• Oncology
• Dermatology

Background:

• Metabolic processes generate reactive oxygen species (ROS), which cause oxidative damage linked to aging and diseases like cancer.
• ROS were once viewed as harmful byproducts but are now recognized for their roles in cell signaling and cancer therapy.
• Melanoma, a deadly skin cancer, is influenced by ROS, necessitating a deeper understanding of their complex roles.

Purpose of the Study:

• To review the types, sources, and pathways of ROS in melanoma.
• To explore the dual roles of ROS in antioxidant/oxidant regulation, hypoxia, metabolism, and cell death.
• To discuss the implications of ROS in physical therapy modalities for melanoma treatment.

Main Methods:

• Literature review of ROS in melanoma.
• Analysis of ROS involvement in cellular processes (antioxidant regulation, hypoxia, metabolism, cell death).
• Examination of ROS in physical therapies including radiotherapy, electrochemotherapy, hyperthermia, photodynamic therapy, and medical gas plasma.

Main Results:

• ROS play multifaceted roles in melanoma, influencing cell survival and death.
• ROS are integral to the efficacy of various physical therapy modalities used against melanoma.
• Understanding ROS mechanisms can illuminate strategies to overcome therapy resistance in melanoma.

Conclusions:

• ROS are critical players in melanoma biology and therapeutic responses.
• Targeting ROS pathways presents a promising strategy for enhancing melanoma treatment outcomes.
• Further research into ROS is essential for developing more effective therapies against melanoma and overcoming resistance.
