Current state of research on copper complexes in the treatment of breast cancer.

Breast cancer, a malignancy originating from the epithelium or ductal epithelium of the breast, is not only highly prevalent in women but is also the leading cause of cancer-related deaths in women worldwide. Research has indicated that breast cancer incidence is increasing in younger women, prompting significant interest from scientists actively researching breast cancer treatment. Copper is highly accumulated in breast cancer cells, leading to the development of copper complexes that cause immunogenic cell death, apoptosis, oxidative stress, redox-mediated cell death, and autophagy by regulating the expression of key cell death proteins or assisting in the onset of cell death.

miR-129-2-3p mediates LPS-induced macrophage polarization and ferroptosis by targeting the SMAD3-GPX4 axis.

Macrophages has become a promising target of sepsis treatment because macrophages dysfunction contributes to the progress of sepsis. The targeted therapy of sepsis based on macrophages ferroptosis is drawing more and more attention, but the molecular mechanism involved is poorly understood. In this study, Mus musculus-derived macrophages were used for in-vitro experiments.
