PHKA1 and diffuse large B-cell lymphoma: According to the optimal cutoff value for each gene, we divided the 104 DLBCL samples in the TMA cohort into high- and low-expression groups (high-PLTP expression: n = 36, low-PLTP expression: n = 68; and high-PHKA1 expression: n = 40, low-PHKA1 expression: n = 64).
