Fig. 5. (a & b) The viability of MCF-7/ADR cells after different treatments for 24 h with an MMC concentration of (a) 0.5 μg mL^–1 and (b) 10 μg mL^–1. (c) The ROS generation monitored by DCF luminescence for MCF-7/ADR cells after different treatments. (d_1–8) Flow cytometry analysis for apoptosis of MCF-7/ADR cells after different treatments: (d₁) control, (d₂) MMC, (d₃) RUMSNs–MMC, (d₄) RUMSNs–TAT–MMC, (d₅) RT, (d₆) MMC + RT, (d₇) RUMSNs–MMC + RT, and (d₈) RUMSNs–TAT–MMC + RT. [MMC] = 10 μg mL^–1.
