Distinct gene expression profiles in Ph-positive and -negative patient groups as determined by a hierarchical clustering and b principle component analysis. a Each column represents a chip, and each row represents a specific gene. The gene expression level at each treatment point was subtracted from the first time point (T0). The color map uses red and green for high and low expression values, respectively. Black corresponds to genes exhibiting non-significant variation. b Three-dimensional plot of the first three principal components by the matrix containing 80 % of the information. Ph-positive and -negative patients are indicated as closed squares and open circles, respectively
