Question 1

What intracellular conditions are required for efficient chemodynamic therapy?

Accepted Answer

Efficient CDT requires self-supply of H2O2 inside cells while simultaneously depleting glutathione (GSH) to enable oxidative stress–mediated cancer killing.

Question 2

How does the CaO2-DOX-CuMOF/PEG nanoplatform respond to GSH in cancer cells?

Accepted Answer

GSH-rich cancer cells disintegrate CaO2-DOX-CuMOF/PEG, releasing DOX and CaO2. The freed components promote formation of H2O2, which drives reactive oxygen species (ROS) generation and oxidative stress.

Question 3

What evidence supports the benefit of combining chemo−chemodynamic therapy in this study?

Accepted Answer

Antiproliferative performance was assessed in vitro using lung adenocarcinoma cells via cytotoxicity, intracellular ROS generation, and mitochondrial membrane potential, and in vivo in a mice tumor model where the combined therapy outperformed individual therapies.
