Differential expression of MYC targets in miRNA-driven subsets of DLBCL. Box plot display of the real-time RT-PCR analyses of 3 independent MYC target genes, CAD (carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, and dihydroorotase), PGK1 (phosphoglycerate kinase 1), and TFAM (transcription factor A, mitochondrial) in 24 primary DLBCL samples (16 assigned to MG-A and 8 to MG-C). As hypothesized, MYC activity, defined by the expression of these target genes, was significantly higher in MG-A tumors (P < .01, Mann-Whitney test [CAD and PGK1] and P < .05 [TFAM]).
