[The advancement of cuproptosis in hematological tumors]

Cuproptosis is a type of independent cell death form, that differs from apoptosis, necroptosis and ferroptosis. It is mediated by Copper (Cu), and mainly affects the lipoylation of proteases in the mitochondrial tricarboxylic acid (TCA) cycle and exhibits cytotoxicity through oligomerization; however, its specific mechanism, signal transduction process and regulation mode are still not clear. Mitochondria affect the sensitivity of cells to copper toxicity and play a central role in the occurrence and development of copper-related death. In recent years, though hematological tumors have achieved better remission through targeted therapy and immunotherapy, they are associated with high recurrence rates and poor prognoses. It is therefore imperative to find better prognostic indicators and new treatment ideas. This paper summarizes the interaction between Cu and mitochondria in the development of tumors and provides ideas for further exploration of the mechanism of copper death and coping with hematological tumors.
