Hypothesis

This study intended to examine the effect of disulfiram on breast cancer stem cells.

Conclusion

Disulfiram/copper inhibited breast cancer stem cells and enhanced the cytotoxicity of paclitaxel in breast cancer cell lines.

Supporting Evidence

  • Disulfiram was highly toxic to breast cancer cell lines in a copper-dependent manner.
  • Disulfiram/copper significantly enhanced the cytotoxicity of paclitaxel.
  • Disulfiram/copper induced reactive oxygen species generation and activated apoptosis-related pathways.

Takeaway

Disulfiram, a drug used for alcoholism, can also kill breast cancer cells, especially when combined with copper, making chemotherapy more effective.

Methodology

The effect of disulfiram on breast cancer cell lines and breast cancer stem cells was determined using MTT assays, western blotting, and clonogenic assays.
