We observe the expression of HIF-1 after middle cerebral artery occlusion (MCAO) by immunohistochemical method.Thirty-six Sprague-Dawley healthy male rats, with body mass of 250-330 g, were used in this study. Thirty-six rats were randomized into 3 groups: pre-ischemia group, sham-operation group and control group, with 12 rats in each.Rats in the pre-ischemia group were created into pre-ischemia...
This study was comparison of MGMT and ERBB2 expression in human gliomas. RT-PCR method was used to determine the mRNA levels of MGMT and ErbB2 gene in 42 clinical glioma specimens,There was significant concordance between the expression of MGMT and ErbB2 (p < 0.01). MGMT and ErbB are highly remarkably related each other. The results suggest that there may be in relationship among MGMT and ErbB2...
AIM: To evaluate the role of survivin and caspase-3 in apoptosis of gastric carcinoma, as well as in prognosis of patients with gastric carcinoma. METHODS: Expressions of survivin and caspase-3 were investigated immunohistochemically in 80 gastric carcinoma patients without a history of chemo-radiation therapy. Tumor cell apoptosis was examined by TUNEL method. RESULTS: Immunohistochemical analysis...
Study the role of Fas ligand (FasL) expression in carcinogenesis and progression of esophageal cancer and molecular mechanisms of relevant immune escape. FasL expression was studied in adjacent epithelial cells, cancer cells and lymphocytes of primary foci, and cancer cells of metastatic foci from 40 cases of esophageal cancer by immunohistochemistry. The relationship between FasL expression in cancer...
The objective of this study is to investigate the relationship between caspase-3 expression and apoptosis in the gastric adenocarcinoma cell line SGC-7901 transfected with the adenovirus-mediated FasL gene. The human gastric adenocarcinoma cell line SGC-7901 was transfected with the adenovirus-mediated FasL gene. The expression of caspase-3 and apoptotic morphological changes were measured by flow...
