Figure Lengend Snippet: Cu-doped Prussian blue (CuPB) nanozymes protect C2C12 myoblasts and H9c2 cardiomyocytes from H 2 O 2 -induced oxidative injury. (A and B) Representative fluorescence images and quantification of intracellular reactive oxygen species (ROS) in H 2 O 2 -injured C2C12 cells after Prussian blue (PB) or CuPB treatment, detected using the 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA) probe. Scale bar: 50 μm. n = 5. (C and D) Representative terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining images and quantification of apoptotic C2C12 cells following H 2 O 2 injury with PB or CuPB treatment. Scale bar: 50 μm. n = 5. (E) Quantitative real-time polymerase chain reaction (qRT-PCR) analysis of apoptosis-related genes ( Bcl2 , Caspase3 , Caspase9 , and Bax ) in C2C12 cells after different treatments. n = 3. (F and G) Representative fluorescence images and quantification of intracellular ROS in H 2 O 2 -injured H9c2 cells after PB or CuPB treatment, detected using the DCFH-DA probe. Scale bar: 50 μm. n = 5. (H and I) Representative TUNEL staining images and quantification of apoptotic H9c2 cells following H 2 O 2 injury with PB or CuPB treatment. Scale bar: 50 μm. n = 5. (J) qRT-PCR analysis of apoptosis-related gene expression ( Bcl2 , Caspase3 , Caspase9 , and Bax ) in H9c2 cells after different treatments. n = 5.
