Cu(GlyGlyHis) effects on MCF7 cells: Copper uptake, reactive oxygen species generation and membrane topography changes

► Cu(GlyGlyHis) causes breast cancer MCF7 cells proliferation. ► The copper uptake induces ROS accumulation. ► The high ROS levels are not able to generate redox imbalance in MCF7 cells. ► The lipid oxidation in copper-treated cells triggers external mechanical adaptations.
