Fig. 5From: Fetal hypoxia and apoptosis following maternal porcine reproductive and respiratory syndrome virus (PRRSV) infectionApoptosis and hypoxia gene expression in fetal thymus. Box-and-whisker plot of twelve target genes analyzed in fetal thymus for each of the four fetal phenotypic groups (represented by different colours). The Y-axis presents the fold change, the X-axis presents the targeted genes. Superscript letters indicate statistical differences among groups for individual genes (P < 0.05)Back to article page
