MKI67 and non-small cell lung carcinoma: The delayed tumor growth was further accompanied by a decrease in proliferation index as seen by reduced ki67 staining in both pancreatic (P = 0.0066) and lung tumor tissues (P = 0.022) (Fig. 5, g, h, and Supplementary Fig. 6c), with a concomitant increase in cleaved caspase-3 expression (PC, P = 0.0052; NSCLC, P = 0.0377) (Fig. 5, i, j).
