Cortical mRNA levels of BDNF showed a trend (P = 0.068) to be decreased (Figure 5) and the Bcl-2 mRNA level was significantly decreased in the P7 IUGR group (Figure 5), whereas no statistical difference with IUGR_Lf was observed (Figure 5) compared to CTL. This evidence concerns the gene BCL2 and fetal growth restriction.
