Cancer cell membrane and associated reactive oxygen species-generating pathways

Cancer cell membranes and associated reactive oxygen species (ROS)-generating pathways represent a complex therapeutic target system that exploits the unique redox environment and membrane characteristics of malignant cells (Source: NIH, PubMed). This target involves the localization of therapeutic agents at the plasma membrane or within membrane-bound organelles to catalyze the production of cytotoxic ROS, such as singlet oxygen, superoxide, and hydroxyl radicals (Source: MDPI). Key molecular components include membrane-bound enzymes like the NADPH oxidase (NOX) family and the mitochondrial electron transport chain, which are frequently upregulated in cancer to drive proliferation and survival (Source: AACR). Therapeutic interventions, such as photodynamic therapy (PDT), sonodynamic therapy (SDT), and chemodynamic therapy (CDT), aim to overwhelm the cell's antioxidant capacity, leading to extensive lipid peroxidation, loss of membrane integrity, and the induction of cell death pathways like apoptosis and ferroptosis (Source: ACS). While this approach offers a way to bypass traditional drug resistance, achieving high tumor specificity is essential to prevent systemic toxicity and damage to healthy cellular membranes (Source: ResearchGate).
