Global analysis of microarray data. Figures A and B show the high reliability and reproducibility of the data. A. Principal component analysis (PCA) score plots, and B. hierarchical clustering (HCL) of the samples. C. Venn diagram of expression profiles of differentially expressed genes (up-regulated and down-regulated) detected in the microarray analysis. The sample names are the same as those in FigureĀ 1C.
