LDLR and hydrops fetalis: Although LDLr mRNA expression was increased (P < 0.05, 1.4-fold of HF control) in the HF + EX group compared with the HF animals (Figure 4(a)), we observed no change (P > 0.05) in LDLr protein abundance in hepatic total tissue or membrane extracts between trained and untrained animals (Figures 4(b), and 4(c)).
