PPARA and hydrops fetalis: At the transcriptomic level, DEGs detected in the Group G vs. Group HF comparison were significantly (p < 0.05) enriched for 63 KEGG terms (Table S2) and were mainly distributed in the terms AMPK signaling pathway, glycolysis/gluconeogenesis, FoxO signaling pathway, PPAR signaling pathway, and ECM–receptor interaction (Figure 1D).
