Mechanism diagram. Annotation: Specific miRNAs upregulated or downregulated by DSS-Exo include hsa-miR-126-3p_R-1, hsa-miR-223-3p, hsa-miR-122-5p_R-1, among others, which modulate genes related to fibrosis such as α-SMA, CTGF, E-cadherin, Fibronectin, VEGFA, and HIF-1α. DSS-Exo modulate the STAT3 transcription factor, which binds to the SHANK2 promoter, influencing gene transcription
