Their growth after DFO treatment was decreased but not fully inhibited (growth rate of MCL vs non‐MCL cell lines at 48‐hour time point was significantly different, P < .05; Figure 1B, left panels), suggesting that the overexpression of cyclin D1 augments the sensitivity of MCL cell lines to treatment with DFO. The gene discussed is CCND1; the disease is mantle cell lymphoma.
