Abstract:
Objective To investigate the contribution of Cystatin C to the preoperative diagnosis and clinical therapy of gastroenteric tumor.Methods Using surgical materials from patients with stomach, colon and rectum cancer, immunohistochemisty, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting analysis were performed with antibodies against Cystatin C.Cystatin C of the cancerous and paired noncancerous lesions were determined by enzyme-linked immunosorbent assay (ELISA).Results (1)Immunohistochemical staining of Cystatin C was evident expression in cancer cells and associated stromal tissues, this was not the case in paired noncancerous tissues,there were also statistical relationship between the expression of Cystatin C in cancerous and that in noncancerous tissues (?~2=6.825,P
