Nanozyme-mediated glutathione depletion for enhanced ROS-based cancer therapies: a comprehensive review.

Nanozymes can improve reactive oxygen species (ROS)-based cancer therapies by targeting cancer cells' antioxidant defense mechanisms, particularly glutathione (GSH) depletion, to overcome ROS-resistant cancer cells. Nanozymes, innovative enzyme-mimetic nanomaterials, can generate ROS, alter the tumor microenvironment (TME), and synergize with photodynamic therapy (PDT), chemodynamic therapy (CDT), radiotherapy, and immunotherapy. This review shows how nanozymes catalyze ROS generation, selectively deplete GSH, and target cancer elimination, offering clear advantages over standard therapies.

Synergistic Anticancer Strategy Targeting ECM Stiffness: Integration of Matrix Softening and Mechanical Signal Transduction Blockade in Primary Liver Cancers.

The development of primary liver cancer (hepatocellular carcinoma [HCC] and intrahepatic cholangiocarcinoma [ICC]) is linked to its physical microenvironment, particularly extracellular matrix (ECM) stiffness.
