CDKN1C and fetal growth restriction: When sham and IUGR data were combined, there was a significant negative correlation between the expression of Dnmt3a and lncRNA Kcnq1ot1 at E20 (Spearman’s ρ = −0.455, p = 0.006, Fig. S1a and Table S3), as well as significant positive correlations between Dnmt3a and Kcnq1 and Dnmt3a and Cdkn1c (Spearman’s ρ = 0.896, p < 0.0001 and Spearman’s ρ = 0.349, p = 0.040, respectively; Fig. S1a and Table S3).
