CC-122 induces growth arrest and apoptosis in ABC- and GCB-DLBCL cell lines. (A) Multiple DLBCL cell lines were treated with dimethylsulfoxide (DMSO) and CC-122 (0.01-10 000 nM) for 5 days. Proliferation for all cell lines was determined using the 3H-thymidine incorporation method. Results of 3 independent experiments are shown (mean ± standard error of the mean [SEM]). (B) DLBCL cell lines were treated with DMSO, and CC-122 (0.1-10 μM) for 7 days, after which apoptosis was measured by Annexin V and To-Pro 3 flow cytometric analysis.
