Figure 4From: Ancestral exposure to stress epigenetically programs preterm birth risk and adverse maternal and newborn outcomes Ancestral stress alters brain miRNA expression. (A) Heat map of miRNA expression modulated by multigenerational stress in brains of F2-SSS dams. (B) Confirmation of miRNA level changes in brains of F0-S and F2-SSS compared to non-stress F0-N rats by qRT-PCR. Ancestral programming by stress particularly involved the miR-200 family. Sno202, U6 and 5Â s rRNA were used as references. Asterisks indicate significances: *P <0.05; **P <0.01, compared to F0-S levels.Back to article page
