Figure Lengend Snippet: CircRNA profiles in BALF EVs, serum EVs and BALF cells. Three mice were used in this experiment. BALF and serum were collected and pooled after exposure to PBS or LPS (1µg/mouse) or HCl (0.1N) for 24h. EVs were separated using ultracentrifugation as previously described . RNA was isolated from the EVs and subjected to circRNA microarrays by Arraystar Inc (Rockville, MD). Heatmap of the circRNA arrays in EVs obtained from BALF in the absence and presence of noxious stimuli. (A) BALF EVs obtained from mice that were exposed to PBS or LPS. (B) BALF EVs obtained from mice that were exposed to PBS or HCL. (C) the changes of EV-cargo circRNA profiles between non-infectious stimuli (HCL) and endotoxin (LPS) were expressed in Log2 fold change. (D) A representative picture showing the histological changes was presented here. The inflammatory score was determined by a double-blinded examiner using five lung sections per mouse, and three mice per treatment. The mean value is graphed and presented. ***p<0.05.
