IGF2 and hydrops fetalis: There was an effect of the maternal diet on Igf2 expression (two-way ANOVA, p = 0.001, Fig. 2a), and that the ovaries in offspring from HF-fed dams (i.e., the HF/C and HF/HF groups) showed a significant increase in expression levels compared with the levels found in the ovaries of offspring from C-fed mothers (i.e., with a 1.58-fold increase in HF/C vs. C/C, p = 0.004, one-way ANOVA).
