Furthermore, to investigate the functions of HF-related genes, we annotated these genes into GO and KEGG pathway analysis, we found that the DE genes were remarkably enriched in the GO terms involving TGF-β signaling pathway, ECM-receptor interaction, PPAR signaling pathway, etc. It is well known that activated hepatic stellate cells (HSCs) are famous for their role in liver fibrosis. Here, TGFB1 is linked to hydrops fetalis.
