MKI67 and cancer: NCBP1‐silenced tumours showed fewer cancer‐specific morphological features than control tumours; Ki‐67 staining suggested there was a lower degree of proliferation in NCBP1‐silenced tumours; and a TUNEL assay suggested that there were greater levels of apoptosis in NCBP1‐silenced tumours than in the controls (Figure 7B).
