Microarray results overview. The Venn diagrams illustrate the results of the 2 x 2 ANOVA (A) and the contrast comparison between arteries within age group (B). The volcano plots illustrate the overall microarray data for differential gene expression between brachial and femoral arteries in the nine month (C) and two (D) year old Rapacz FHC swine. The points indicate the log2(fold-change) (on the x-axis) and the –log10(FDR adj. P value) (on the y-axis) for each probe set with sufficient signal. The horizontal line (y = 1.3) specifies the FDR cut-off for significance (FDR = 0.05).
