Figure Lengend Snippet: Fig. 2. Silica exposure induces mitochondrial depolarization and disrupts energy homeostasis in RAW-ASC cells. RAW-ASC cells were primed with LPS for 6 h then treated with nano-silica, micro-silica, and ATP for 4 h, respectively. (A) Representative images of JC-1 staining showing the alteration of mitochondrial membrane potential between groups. Red, JC-1 aggregates; Green, JC-1 monomers. Scale bar = 50 µm. (B) Quantitative analysis and comparison of fluorescence intensity in A between groups (n = 6). (C) Measurement and comparison of intracellular ROS content between groups (n = 6). (D) Measurement and comparison of intracellular ATP content between groups (n = 4). ns, not significant, *P < 0.05, **P < 0.01.
