Published: April 14, 2023

Copper is an essential trace element in biological systems, maintaining the activity of enzymes and function transcription factors. However, at high concentrations, copper ions show increased toxicity by inducing regulated cell death, such as apoptosis, paraptosis, pyroptosis, ferroptosis, cuproptosis. Furthermore, can trigger macroautophagy/autophagy, a lysosome-dependent degradation pathway that plays dual role regulating survival or death fate cells under various stress conditions. Pathologically, impaired metabolism due to environmental genetic causes implicated variety human diseases, rare Wilson disease common cancers. Therapeutically, copper-based compounds are potential chemotherapeutic agents be used alone combination with other drugs approaches treat cancer. Here, we review progress made understanding metabolic processes their impact on regulation autophagy. This knowledge may help design future clinical tools improve cancer diagnosis treatment.
