Innovative cross-intervention: copper ions and metabolic pathways in cancer therapy

Area of Science:

• Oncology
• Cellular Metabolism
• Molecular Biology

Background:

• Copper ions are essential for cellular functions but can lead to cytotoxicity when dysregulated.
• Cancer cells exhibit altered copper metabolism, often with elevated levels supporting tumor growth and metastasis.
• Cuproptosis, a novel regulated cell death pathway, is induced by copper accumulation.

Purpose of the Study:

• To review the role of copper in cancer metabolism.
• To explore the mechanisms of cuproptosis and copper homeostasis.
• To discuss therapeutic strategies involving copper in cancer treatment.

Main Methods:

• Literature review of copper metabolism, homeostasis, and cuproptosis in cancer.
• Analysis of key copper transporters (CTR1, ATP7A/B) and their roles.
• Examination of copper-based nanotechnology and its application in cancer therapy.

Main Results:

• Copper dysregulation in cancer supports proliferation and metastasis.
• Cuproptosis involves lipoylated mitochondrial protein aggregation and iron-sulfur cluster disruption.
• Copper-based nanomedicine enhances anti-cancer effects via ROS generation and immunomodulation.
• Hypoxic tumor microenvironments present challenges by upregulating copper sequestration.

Conclusions:

• Targeting copper metabolism and inducing cuproptosis offers a promising oncologic intervention strategy.
• Further research integrating multi-omics and combination therapies is needed to overcome resistance.
• Copper-based therapies hold potential for synergistic effects and improved cancer treatment outcomes.
