GM-CSF enhanced the effect of CHOP and R-CHOP on the production of β2-MG, LDH and CD20. a, b The ELISA assay was performed to detect the level of β2-MG, LDH in the serum of DLBCL-bearing mice. c IHC was performed to evaluate the expression of CD20 in the tumor of DLBCL. *p < 0.05, **p < 0.01 vs. Control, #p < 0.05 and ##p < 0.01 vs. CHOP, @@p < 0.01 vs. CHOP + GM-CSF, $p < 0.05 and $$p < 0.01 vs. R-CHOP. Data are representative of at least three independent experiments
