REACTOME pathway enrichment analysis in iWAT showed that among 1026 identified pathways (25,254 identified genes), 99 gene sets (137 transcripts) were differentially expressed between the LFABP−/− and WT mice (FDRq < 0.1), with 61 upregulated (74 transcripts) and 38 downregulated (63 transcripts) in the HF-fed LFABP−/− mice (|FC| > 1.2). Here, FABP1 is linked to hydrops fetalis.
