The GO and pathway analysis revealed that the 52 differentially expressed DNBs are enriched in known important fibrosis‐associated pathways, such as retinol metabolism, TGF‐β signalling pathway, ECM‐receptor interaction, focal adhesion, hepatic fibrosis/HSC activation, HIF1α signalling, MMP inhibition, LXR/RXR activation and retinol biosynthesis. This evidence concerns the gene HIF1A and Hepatic fibrosis.
