Figure 3From: Down-regulation of NKD1 increases the invasive potential of non-small-cell lung cancer and correlates with a poor prognosis Immunohistochemical staining of NKD1 in NSCLC. NKD1 was expressed in the cytoplasm of normal bronchial epithelial cells (Normal expression) (A). NKD1 expression was significantly decreased in lung squamous cell carcinoma (B) and adenocarcinoma (C) (Reduced expression). Negative controls were prepared by non-immune rabbit IgG at the same dilution as for the primary antibody in normal (D) and tumor sample (E and F).Back to article page
