MKI67 and neoplasm: The quantification of KI‐67‐ and CC3‐positive nuclei for tumour tissue samples (TT) and benign tissue (BT), with and without treatment (untreated, UT) is shown in Figure 7E, F. This confirmed that AR‐C155858 caused a decrease in proliferation (p < 0.0001) and increased apoptosis (p < 0.0001) in tumour tissues, with no significant effect on benign tissue (p = 0.1086 and p = 0.6993, respectively).
