ObjectiveTo study the expression of urokinase-type plasminogenactivator (uPA) and phosphorylation of glycogen synthase kinase-3β (P-GSK3β) in human colorectal adenocarcinoma and its significance.
MethodsSeventy-eight samples of colorectal adenocarcinoma got during operation between January 2006 and December 2010 in Handan Central Hospital were chosen as the study subjects. The immunohistochemical SP method was used to detect uPA and P-GSK3β levels in the 78 cases of colorectal adenocarcinoma, 20 cases of normal colorectal mucosa and 30 cases of colorectal adenoma.
ResultsThe positive expression rates of uPA and P-GSK3β in colorectal carcinoma were much higher than those in colorectal mucosa, colorectal polyps, and colorectal adenoma (P<0.05). The expressions of uPA and P-GSK3β were closely correlated with the differentiation, TNM and lymph nodes metastasis (P<0.05).
ConclusionThe expression of uPA and P-GSK3β is closely related to the colorectal adenocarcinoma occurrence. Both of them are important biological markers in colorectal adenocarcinoma occurrence and development.
