Concordance between microarray experiments. Overlap of statistically significant differentially expressed genes across the three repeated microarray experiments is shown in (A). Log2 fold-changes (FCs) for genes which were significantly upregulated in each of the three experiments were averaged across replicates within each experiment (n = 5 for Experiments 1 and 2; n = 4 for Experiment 3). Pairwise scatter plots among these averaged FCs are shown in (B-D). The regression lines are: the identity line (red), least-squares (blue) and loess (yellow).
