Expression of PAK4 and the association with progression in NSCLC. a Representative western blots of PAK4 expression (left) in NSCLC tissues (T) and matched adjacent non-tumor tissues (N); the quantitative intensities′ data of PAK4 protein bands of 20 NSCLC tissues and matched adjacent non-tumor tissues. b: The mRNA expression of PAK4 in 20 NSCLC tissues and matched adjacent non-tumor tissues by RT-PCR. c: PAK4 expression in primary NSCLC cancer tissues of 10 patients without metastasis and 10 patients with metastasis. d: Representative immunohistochemical staining (top panels) and statistical analysis (bottom panels) of squamous cell cancer (left) and adenocarcinoma (right) of human NSCLC tissues (T) and matched adjacent non-tumor tissues (N) under at × 40 original magnification. Positive cells are stained brown. P, patient
