Differential mRNA expression. This Venn diagram displays the number of differentially expressed transcript per experimental group compared to controls, including the number of up- and downregulated transcripts, at 6 and 96 hours after birth. (FA: experimental group only subjected to fetal preconditioning. PA: experimental group only subjected to perinatal asphyxia. FAPA: experimental group subjected to both fetal preconditioning and perinatal asphyxia).
