The profile of miR-9-3 methylation of seven CLL cell lines was shown in Figure 2A. I83-E95 and WAC3CD5+ cell lines showed complete methylation of miR-9-3, 232B4, CLL-AAT and HG3 partial methylation while MEC1 and MEC2 were completely unmethylated. Here, ATR is linked to B-cell chronic lymphocytic leukemia.
