At the transcriptomic level, DAPs detected in the Group G vs. Group HF comparison were significantly (p < 0.05) enriched for 35 KEGG terms (Table S3) and were mainly distributed in the terms ribosome; FA degradation; alanine, aspartate, and glutamate metabolism; PPAR signaling pathway; and FA metabolism (Figure 3D). Here, PPARA is linked to hydrops fetalis.
