MiR-222-3p directly targets Bim. A Venn diagram showing the number of genes. significantly upregulated in ATMs from obese donors compared with ATMs from lean donors according to microarray analysis and the number of potential targets of miR-222-3p predicted by target prediction algorithms. B Enrichment analysis of pathways performed by Metascape. C Predicted binding sites between miR-222-3p and the Bim 3'-UTR. D Dual-luciferase assays were performed in HEK293T cells after co-transfection with Bim 3'-UTR wild-type (WT) or mutant (MUT) plasmids and miR-222-3p mimic or miR-NC mimic. *P < 0.05 compared with the WT group by repeated-measures analysis of variance (n = 3). E, F Western blotting was used to analyze Bim and β-actin protein levels in RAW264.7 cells treated with LPS, LPS + ExosLean, LPS + ExosLean + miR-222-3p inhibitor, or LPS + ExosLean + miR-NC inhibitor. *P < 0.05, #P < 0.05 by repeated-measures analysis of variance (n = 3)
