Figure Lengend Snippet: HG and PA treatments induce ROS over-production, oxidative stress, and mitochondrial dysfunction in macrophages. ( A ) Representative intracellular ROS photographs using DCFH-DA fluorescence probe in control RAW264.7 macrophages and those with treatments of 25 mmol/L HG and 60 μM PA for 48 h. Scale bars, 50 μm. ( B ) Quantification of fluorescence intensity of ROS in control and HG- and PA-induced RAW264.7 macrophages. ( C and D ) Measurement of MDA and GSH levels in control and HG- and PA-induced RAW264.7 macrophages. ( E ) Representative JC-1 staining photographs in control and HG- and PA-induced RAW264.7 macrophages. Green fluorescence represents that MMP is low and JC-1 exists in the cytoplasm in the form of monomer. Red fluorescence represents that MMP is high and JC-1 polymer is formed. Scale bars, 50 μm. ( F ) Calculation of a ratio of green fluorescence and red fluorescence for quantification MMP changes. ( G ) Detection of ATP in control and HG- and PA-induced RAW264.7 macrophages. ( H ) TEM for investigating the changes in mitochondrial morphology in control and HG- and PA-induced RAW264.7 macrophages. Scale bars, 500 nm. **, P<0.01; ***, P<0.001; ****, P<0.0001 derived from Student’s t test.

Article Snippet: After 24 h, 300 μL JC-1 staining solution (C2006; Beyotime) was added, with additional 20-min cultivation in the dark at 37°C.

Techniques: Fluorescence, Control, Staining, Polymer, Morphology, Derivative Assay

Scale bars, 50 μm. ( B ) Quantification of fluorescence intensity of ROS in control macrophages, HG- and PA-induced macrophages, and HG- and PA-induced macrophages with CMA treatment.
