Abstract

5FCN nanoparticles demonstrate superior cell-killing efficacy against triple-negative breast cancer (TNBC).

  • 5FCN nanoparticles utilize a dual mechanism of ferroptosis and cuproptosis to target TNBC cells.
  • Hyaluronic acid in 5FCN selectively binds to CD44 receptors, facilitating entry into TNBC cells.
  • The release of iron and copper ions in acidic environments disrupts the antioxidant defense system in tumor cells.
  • Toxic hydroxyl radicals are generated through reactions involving the released metal ions, promoting ferroptosis.
  • Increased copper levels within cells lead to the aggregation of specific proteins, enhancing cuproptosis.
