CLDN7 and hydrops fetalis: Maternal HF diet was also associated with an increase in fetal gut mRNA expression of TJ genes Cldn-3 (p = 0.008, Figure 7A) and Cldn-7 (p < 0.001, Figure 7B) compared to CON, while UN fetuses only displayed increased mRNA expression of Cldn-7 compared to CON (p < 0.001, Figure 7B).
