Ranking of tyrosine kinase (TK) genes based on expression in AML. Expression microarray data were obtained from 92 de novo AML patient bone marrow samples from the WU Discovery set samples. Normalized absolute expression values are shown for all annotated RTKs (A) and CTKs (B) on the Affymetrix U133 Plus 2 array platform. Genes that were sequenced in this study are indicated by the black bars.
