Fig 4. Hierarchical heat map showing the expression dynamics of DEGs.
Normalized log2 transformed values as determined by Affymetrix GeneChip® porcine gene 1.0 ST array in PBMCs of Pietrain pigs collected at D0, D1 and D28 of PRRSV vaccination. Each column represents one pig, three replicates at each time point, each horizontal line refers to one gene. The cutoff value of log fold change as >1.5 or <−1.5 and false discovery rate <0.01 was considered.
