Similar results were also obtained for CBX2 (DLBCL specimens: 0.351 ± 0.098; control groups: 0.065 ± 0.041, P < 0.0001), CBX3 (DLBCL specimens: 0.374 ± 0.112; control groups: 0.064 ± 0.028, P < 0.0001) , CBX5 ( DLBCL specimens: 0.420 ± 0.127; control groups: 0.058 ± 0.025, P < 0.0001) and CBX6 ( DLBCL specimens: 0.379 ± 0.115; control groups: 0.072 ± 0.032, P < 0.0001) protein expression. Here, CBX2 is linked to diffuse large B-cell lymphoma.
