Genome-wide profiling of RXRα/nuclear receptor binding sites. (A) A dendogram was generated by cluster analysis to show RXRα/nuclear receptor (NR) binding sites. Each horizontal line represents a binding site. White regions indicate there is no peak called. The lengths of the vertical lines represent the distance between the sets of target genes for the nuclear receptors when clustered. (B) A score plot of PCA analysis for RXRα/nuclear receptors binding sites. Scores of component 1 and 2 were obtained from the linear combination of all the nuclear receptors binding sites.
