PPARG and hydrops fetalis: As shown in Figure 3D, adipocyte protein 2 (aP2), peroxisome proliferator-activated receptor γ (PPARγ), and stearoyl-CoA desaturase-1 (SCD-1) mRNA levels were significantly higher in eWAT from HF-fed obese mice compared to NOR-fed animals, whereas the supplementation of HF with vitamin D showed a significant reduction in aP2 and PPARγ gene expression by 41% and 39%, respectively, compared to HF (p < 0.05).
