TG and hydrops fetalis: KEGG analysis showed that target genes of these DEmiRNAs were enriched in 44 KEGG terms, in which the KEGG pathways related to HF development, including the Notch signaling pathway, melanogenesis, cAMP signaling pathway, cGMP-PKG signaling pathway, estrogen signaling pathway, thyroid hormone signaling pathway, phosphatidylinositol signaling system, and phospholipase D signaling pathway, were significantly enriched (Supplementary Table S15).
