Figure 1.

Global transcriptional similarity of Chinese and Caucasian samples. Dendrogram, obtained by hierarchical clustering of gene expression (A) and microRNA (miRNA) (B) data of the Chinese–Caucasian cohort, separated samples independently of race/ethnicity. The color bar at the bottom of the dendrogram shows hormone receptor status (assessed by immunohistochemistry) and race/ethnicity. Global genes and miRNA from the Chinese datasets were partioned by hierarchical clustering and the identified groups of correlated genes and miRNAs were validated on Caucasian dataset. The number of genes (C) and miRNAs (D) included in each cluster pair was conserved.
