NPPA and hydrops fetalis: Figure 7G,I showed a significant upregulation in α-ENaC subunit in both decompensated groups as compared to sham-operated rats. It is worth mentioning that the increase was more prominent in the ANP-treated group. α-ENaC mRNA expression was also augmented in decompensated HF with partial attenuation in the ANP-treated group (Figure 7K).
