The results showed that the mRNA expression levels of TSR1, WDR46, HSP90AA1, and NOP56 in DLBCL were significantly higher than those in normal tissues (P < 0.05), but the expression of UBC was not significant (P > 0.05) (Figure 4b and 4f). This evidence concerns the gene HSP90AA1 and diffuse large B-cell lymphoma.
