a Immunohistochemistry analysis of PEAK1 expression in lung cancer tissue and adjacent normal tissue. Scale bar, 100 μm. b Immunohistochemical staining of normal and tumor tissues was evaluated by staining scores. c Immunohistochemical staining of normal, non-metastatic tissues and LN-metastatic tissues was evaluated by staining scores. NS no statistical significance; **P< 0.01; ***P < 0.001
