Dysregulated Wnt signaling confers resistance to cuproptosis in cancer cells
Cuproptosis is characterized by the aggregation of lipoylated components of the tricarboxylic acid cycle and subsequent loss of iron-sulfur cluster proteins as a unique copper-dependent form of regulated cell death. Dysregulation of copper homeostasis and resulting cuproptosis induction is an emerging area of interest for cancer therapy. However, mechanisms of cancer cell evasion of cuproptosis are not well understood. Here, we found a link between copper homeostasis regulated by the Wnt pathway and cuproptosis sensitivity, and may provide a precision medicine strategy for cancer treatment by selectively inducing cuproptosis.
