Fig. 1

Distribution of differentially expressed genes visualized as scattered plots. Each dot represents the mean expression (two biological replicates) of an individual gene obtained from a normalized microarray study. The gray dotted lined (cut-off values) were established according to the following parameters: |fold change|= 2 and p value = 0.05. Genes above the cut-off lines were considered as differentially expressed genes and are shown as orange (down-regulated) and turquoise (up-regulated) dots. The total numbers of up- and down-regulated genes are given in the top right and top left corners, respectively. The symbols of the five most differentially expressed genes from each compression are marked on the plots
