Furthermore, we confirmed CD39 gene upregulation in ABC DLBCL samples (Figure 2B, p < 0.0001 ABC vs. GCB group) and also in the ABC DLBCL-derived cell lines compared with the GCB DLBCL-derived cell lines (p < 0.05) (Figure 2C). The gene discussed is ENTPD1; the disease is diffuse large B-cell lymphoma.
