Furthermore, the elevated expression of specific mitochondrial genes is found to be closely correlated with a unique subtype of DLBCL, OxPhos‐DLBCL, which shows higher tolerance to reactive oxygen species (ROS) toxicity than non‐OxPhos DLBCLs and demonstrates resistance to BCL6 inhibitors [13, 14]. This evidence concerns the gene BCL6 and diffuse large B-cell lymphoma.
