Antitumor effect of DSF/Cu against primary DLBCL cells. Apoptosis statistical chart of primary DLBCL cells (n = 8) and a representative dot plots of a primary DLBCL cells after Cu (1 μM), DSF (400 nM), or DSF/Cu (400 nM/1 μM) treatment for 12 h (B). Mitochondrial membrane potential of primary DLBCL cells (n = 8) and a representative dot plots of a primary CD19⁺ B cells from DLBCL patients after Cu (1 μM), DSF (400 nM), or DSF/Cu (400 nM/1 μM) treatment for 12 h (C). The protein levels of a primary GCB-DLBCL (D) and an ABC-DLBCL (E) after DSF or DSF/Cu treatment. Statistical significance were defined at *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001 compared to control
