Hierarchical clustering and Principal component analysis (PCA) result on the combined data from ES, NP and WB for H3K4me2 binding for 356-gene list. A: Hierarchical clustering. Each row is a range of +/-10kbp on each side of TSS of a gene. The H3K4me2 binding abundance is shown in the color scale. The H3K4me2 binding patterns of the three groups of genes were indicated by the rectangle boxes. The two vertical bars indicate the range of the extended TSS region from each source. B: PCA analysis. The color dots represent different groups from Panel A. The region covers +/- 10kbp of TSS.
