Microtubule-Associated Protein 4 Is a Prognostic Factor and Promotes Tumor Progression in Lung Adenocarcinoma
MAP4 expression in LADC tissues and adjacent normal lung tissues (bar = 100 μm, 200x). (a) Immunohistochemical analysis of MAP4 in tumor tissue samples: (A) negative expression; (B) low expression; (C) moderate expression; (D) high expression. (b) Negative MAP4 expression in adjacent tissues. (c) MAP4 expression was examined by IHC in 91 LADC tissue samples and 86 matched adjacent normal lung tissue samples. MAP4 expression was significantly increased in tumor tissues compared with that in adjacent lung tissues (, paired samples t-test).
