The expression level of 61 genes distinguishes Group A from Group B t-AML. The upper 29 genes have relatively high expression levels in Group A leukemias but not in Group B leukemias. In contrast, the lower 32 genes have relatively high expression levels in Group B leukemias, characterized by a −5/del(5q). Each column represents a leukemia sample, and each row represents the gene indicated by the gene accession numbers and gene symbol or DNA sequence names on the right (note that four genes are represented twice on the array with different oligonucleotides). Red indicates up-regulation and blue depicts down-regulation (see color bar in Fig. 1).
