Figure 5. Sensitivity of KPUM-YY1 and KPUM-YY1R cells to chemotherapeutic agents. Cells were treated with anticancer agents for 48 h and cell viability was evaluated by a modified MTT assay. There was no significant difference between KPUM-YY1 and KPUM-YY1R cells in sensitivity to (A) cytarabine, (B) etoposide, (C) fludarabine, (D) bortezomib, or (E) lenalidomide.
