AFs were transfected for 24 h with Ad-GFP, siR-circEif3c, miR-96–5p mimic, or siR-MEOX2. Migration (A) and proliferation (B) were quantified (C). (D–F) AFs were co-incubated for 48 h with control mimic, Exo-(siR-)circEif3c mimic, Exo-(siR-)miR-96–5p mimic, PVPAC-exosome (Exo-control), GW4869, or Exo-siR-pAd-MEOX2.

Exosomal circEif3c/miR-96-5p/PHF20L1/MEOX2 axis drives vascular remodeling in vivo. (A) Workflow: a stable PVPAC line over-expressing circEif3c supplied exosomes (Exo-Ad-circEif3c, 10 μg/mouse) that were micro-injected into perivascular adipose tissue (PVAT) surrounding the left carotid artery for 4 weeks to initiate remodeling. Subsequently, after the model was established, treatments with (Exo)-Ad-GFP, (Exo)-Ad- circEif3c, (Exo)-Ad-miR-96–5p, and (Exo)-Ad-Meox2 were administered continuously for 2 weeks, respectively. Normal saline (NS) was used as a negative control. (B) Representative H&E-stained cross-sections and concomitant ultrasonography of the common carotid artery. Black scale bars = 50 μm, yellow scale bars = 1 mm, and white scale bars = 0.1 s. (C) Immunohistochemistry. Scale bars = 20 μm. (D) Western blotting. (E) Quantification of protein levels. (F) Tissue localization of Cy5-labeled circEif3c by immunofluorescence, scale bar = 100 μm. (G) Fluorescence intensity quantification. (H) Comparative fluorescence imaging of vascular sections: (H1) Bright-field H&E vs. dark-field GFP before and after Ad-MEOX2 transfection; Scale bars = 50 μm; (H2) DM-remodeling vs MEOX2-intervention groups. Scale bars = 30 μm. (I) Whole-animal in vivo imaging of Cy5 signal. All quantitative data above are presented as mean ± SD. vs. control, ∗ P < 0.01.∗∗ P < 0.01. n (the number of animals) = 6 in each group.
