Consistent with the results obtained in the other NHL cell lines, in Daudi cell, we observed that the synergistic effect of IBTK silencing and Rituximab caused an increase of percentage of cell in subG1 phase (from 11.1% to 24.4%, p value < 0.005) along with a reduction of the percentage of cells in S phase (from 51.7% to 33.57%, p value < 0.05), (Figure 1C). This evidence concerns the gene IBTK and non-Hodgkin lymphoma.
