Clustering of gene-expression and high-resolution array-based CGH data. (A) Unsupervised hierarchic clustering of gene-expression profiles demonstrating 2 distinct groups. (B) Supervised analysis revealing differentially expressed genes between the 2 groups (genes discussed in this paper are listed on the right). (C) Unsupervised hierarchic clustering of array-based CGH data. Numbers correspond to cases as described in Tables 1 and 2.
