Cuproptosis Cell Death Molecular Events and Pathways to Liver Disease

Area of Science:

• Hepatology and trace element metabolism.
• Molecular mechanisms of cell death.
• Oncology and public health.

Background:

• Chronic liver disease and hepatocellular carcinoma (HCC) are leading causes of mortality worldwide.
• Copper is essential but toxic in excess, with the liver regulating its homeostasis.
• Cuproptosis, a copper-dependent cell death, is implicated in various diseases but its role in liver conditions is understudied.

Purpose of the Study:

• To review current research on copper metabolism and cuproptosis in the context of chronic liver diseases.
• To investigate the potential of targeting copper ions for therapeutic interventions in liver disease.
• To provide insights for future research directions in this emerging field.

Main Methods:

• Comprehensive literature review of recent studies on copper metabolism, cuproptosis, and liver diseases.
• Analysis of existing data linking copper dysregulation to liver pathology.
• Exploration of therapeutic strategies targeting copper homeostasis.

Main Results:

• Copper dysregulation is increasingly recognized as a factor in liver dysfunction and disease progression.
• Cuproptosis pathways are implicated in cellular damage within the liver.
• Evidence suggests copper overload and altered cuproptosis contribute to chronic liver conditions.

Conclusions:

• Copper metabolism and cuproptosis are critical, yet underexplored, factors in chronic liver disease pathogenesis.
• Targeting copper ions presents a promising therapeutic avenue for liver diseases, including HCC.
• Further research is warranted to elucidate the precise roles of copper and cuproptosis in liver health and disease.
