“…To investigate the role of P4HA2 in human DLBCLs, we analyzed the expression of P4HA2 and compared it with that of Carabin in the same DLBCL tissues ( Figure 1A; supplemental Table 1) by western blotting (supplemental Figure 8). In .50% cases ( DLBCL 1,2,6,7,9,12,13,14,15,16, and 18; control 2, 3, and 4), there is a negative correlation between P4HA2 and Carabin. Although most cells are B-lymphoma cells in DLBCL tissue, the DLBCL tissues might contain contaminating fibroblasts that express high levels of P4HA2.…”
