摘　　要：Objective： to investigate the expressions of beta-catenin, SUFU and VEGFR-2 proteins in medulloblastoma. Methods： Immunohistochemical staining with SP method was conducted to determine the expressions of beta-catenin, SUFU and VEGFR-2 in 33 cases of medulloblastoma and 10 normal cerebellar tissues. Results： the abnormal expression rates of beta-catenin and VEGFR-2 in medulloblastoma were significantly higher than that in normal tissue. While the positive expression of SUFU gene in medulloblastoma was significantly lower than that in 10 normal cerebellar tissues, A significant negative correlation was found between beta-catenin and SUFU proteins and a positive correlation between beta-catenin and VEGFR-2 was found in medulloblastoma. Conclusion： Beta-catenin, VEGFR-2 and SUFU have important effects on the pathogenesis and development of medulloblastoma.Objective： to investigate the expressions of beta-catenin, SUFU and VEGFR-2 proteins in medulloblastoma.
