MUC2 and hydrops fetalis: On the other hand, mothers exposure to HFD was associated to a significant lower expression of both Muc2 and Muc3 mRNA in the jejunum (0.8-fold, p < 0.0001 and 0.8-fold, p = 0.0163, respectively), in the ileum (0.6-fold, p = 0.0009 and 0.8-fold, p = 0.0062, respectively) and in the proximal colon (0.7-fold, p = 0.0085 and 0.9-fold, p = 0.0041 respectively) in the ctrl-HF as compared to the ctrl-SC (Fig. 7a–c).
