MYC and lymphoma: Relative to control nontransgenic B cells, either pretumoral Eμ‐myc B‐cells or late‐stage lymphomas enriched not only for the MYC signatures, as expected, but also for Hallmark‐OxPhos (albeit with lower significance in the lymphomas, owing most likely to their clonal heterogeneity) [46], while CCC‐OxPhos showed no significant enrichment (Fig. 1B).
