SREBF2 and hydrops fetalis: SREBP1c protein abundance (cytosolic and nuclear) did not differ between the HF and HF + EX groups (Figure 5(a)); however, the HF + EX group demonstrated an increase in nuclear SREBP2 protein abundance (P < 0.05, 1.8-fold of HF control) compared with the HF animals (Figure 5(b)).
