Gene expression profile of MCL-associated genes. A total of 46 MCL-associated genes were identified by filtering the transcriptionally profiled genomes. The relative expression of selected genes is shown for the 21 MCL samples, 5 B-cell populations, and the 3 different MCL cell lines (NCEB1, Granta 519, and SP53). Hierarchic clustering using bootstrapping (n = 100) was performed, and the 5 B-cell populations were shown to be significantly (P < .05) separated from the MCL samples and the tumor cell lines.
