Relationship of VEGF-D and uPA with invasion and metastasis of human colon carcinoma / 第三军医大学学报

ABSTRACT

Objective To explore the expressions of endothelial growth factor-D (VEGF-D) and urokinase-type plasminogen activator (uPA) in colon carcinoma and to reveal their correlation with the tumor invasion and metastasis. Methods The expressions of VEGF-D and uPA were detected by immunohistochemistry and Western blotting in 30 specimens of colon carcinoma and 30 specimens of normal neighbouring colon tissue 5 cm away from the lesions. Results The expressions of VEGF-D and uPA mostly located in endochylema, less in nucleus, of both tumor tissue and normal tissue, and they were significantly higher in tumor tissue than normal tissue (P
