Compared to the control group, in which most tumor cells were Ki67‐positive and cleaved caspase 3‐negative, the number of Ki67‐stained cells decreased notably, whereas the number of cleaved caspase 3‐stained cells increased slightly in the ibrutinib and selinexor single‐agent arms (Fig. 3D). The gene discussed is MKI67; the disease is neoplasm.
