Compared to the Ctrl group, our immunohistochemistry and western blot results showed a significant decrease (P < 0.05) in the level of PTEN protein expression (Figures 6a–6d) with a corresponding significant increase (P < 0.05) in the p-PTEN protein expression in the HF group (Figures 6e–6h). The gene discussed is PTEN; the disease is hydrops fetalis.
