Figure 5: Proliferating cell nuclear antigen (PCNA) expression in tumor tissues (×400) from A549 cell transplanted nude mice. (a) Before administration, the positive cells with PCNA staining showed brown in the cell nucleus; (b) After 60 mmol/L gemcitabine treatment, the positive cells visibly decreased; (c) After 120 mmol/L gemcitabine treatment, showed no positive tumor cells
