(A) JeKo-1 cells were treated with DMSO, or 5μM, 10μM bendamustine, 5μM SGI-1776, or 5μM, 10μM bendamustine combined with 5μM SGI-1776 for 24hr, then cells were incubated with [methyl-3H]-thymidine at 0.8μCi/mL concentration for 45min. Radioactive incorporation was then measured by scintillation count and values were recorded as disintegration per minute (DPM)/cell and normalized to DMSO control. Experiments were performed in triplicate and presented as mean ± SEM.
