MKI67 and neoplasm: Immunostaining of the tissues with an antibody that binds to nuclear antigen ki67, a marker of active cell proliferation, unveiled a compelling diminished count of ki67, brown-stained tumor cells, in 100 counts of DAPI blue-stained total tumor cells (proliferative index) in both the BMS-754807 (BMS) and nab-paclitaxel (NPT) treatment groups compared to that of the vehicle-treated (control) group (Figure 6A,B).
