doi: 10.1002/advs.202519393

Figure Lengend Snippet: Schematic illustration of the synthesis and therapeutic mechanism of mitochondria‐targeted T‐Ag SA ‐CDs for AKI therapy. In cisplatin‐induced AKI, T‐Ag SA ‐CDs (<10 nm) scavenge ROS via SOD‐ and GP X ‐like activities, restore mitochondrial membrane potential (Ψm), and activate the KEAP‐1/Nrf2 pathway, thereby upregulating HO‐1 and GPX4 to enhance antioxidant defense and alleviate renal injury.

Article Snippet: Primary antibodies against NRF2 (80593‐1‐RR), KEAP1 (80744‐1‐RR), HO‐1 (81281‐1‐RR), GPX4 (82822‐2‐RR), β‐actin (81115‐1‐RR), and NF‐κB (80979‐1‐RR), and HRP‐conjugated goat anti‐rabbit IgG secondary antibody (SA00001‐2), were obtained from Proteintech Group, Inc. Chemiluminescent detection was performed using the SuperKine West Pico PLUS substrate (BMU101‐CN, Abbkine Scientific Co., Ltd.).

Figure Lengend Snippet: Effect of NOB, LPS, and INT on oxidative stress ( A ) and Nrf2 signaling pathways ( B ). ROS levels in THLE-2 cells after 24 h treatment with LPS, INT, INT+LPS, and INT+LPS+NOB (25 µM). Non-treated cells and DOXO (100 nM) served as negative and positive controls, respectively. ROS (+) and ROS (−) indicate cells with detectable or undetectable superoxide radicals, respectively. Representative histograms are shown, and data represent mean ± SEM from two independent experiments run in duplicate. Nrf2 subcellular distribution (cytosolic and nuclear fractions) and cytosolic SOD1 levels in THLE-2 cells after 24 h treatment. Representative blots are shown along with the corresponding Stain-Free™ total protein images used for total protein normalization (TPN). Lane order: (1) control, (2) LPS, (3) INT, (4) INT+LPS, (5) INT+LPS+NOB (10 µM), (6) INT+LPS+NOB (25 µM). Band intensities were quantified by densitometry and normalized to the lane-specific total protein signal obtained from Stain-Free imaging. Data are presented as mean ± SEM from two independent experiments, each performed in duplicate. Asterisks above denotes statistical significance relative to the untreated control cells with * p < 0.05, ** p < 0.01. Hashtags above denotes statistical significance relative to the INT+LPS-treated cells with # p < 0.05, ## p < 0.01, ### p < 0.001.
