摘    要:目的探讨膜结构伸展刺突蛋白(Moesin)在人脑星形细胞瘤中的表达及意义。方法应用免疫组织化学链霉菌抗生物素蛋白-过氧化物酶连结法(SP法),检测56例人脑星形细胞瘤和10例正常脑组织中Moesin和磷酸化Moesin的表达,并结合临床随访资料分析表达水平与星形细胞瘤临床预后的相关性。结果Moesin的阳性表达率在人脑星形细胞瘤组96.4%(54/56)和正常脑组织对照组0%(0/10)之间有统计学差异(P〈0.01)。Ⅲ~Ⅳ级星形细胞瘤Moesin的强阳性表达高于Ⅰ~Ⅱ级,两者相比有统计学差异(χ^3=27.50,P〈0.01),磷酸化Moesin的表达结果与Moesin的结果基本一致。Moesin强阳性表达组患者比弱阳性+阴性表达组患者的术后无瘤生存时间短,其差异有统计学意义(χ^2=29.85,P=0.000)。结论Moesin的表达水平与人脑星形细胞瘤的恶性程度密切相关,Moesin的过度表达对星形细胞瘤发展和预后起重要作用,提示Moesin可以作为反映星形细胞瘤预后的一种有价值的分子标志物。

Abstract:Objective To investigate the expression and significance of membrane structure extending spike protein (Moesin) in human astrocytoma. Methods A total of 56 cases of astrocytomas and 10 cases of normal brain tissue were used to detect the expression of Moesin and Phospho-Moesin by immunohistochemical streptavidin-perosidase (SP) method. The data of follow-up were also used to analyze the relationship between the expression level and the clinical prognosis of astrocytoma. Results The positive expression rate ...
Keywords:Astrocytoma  Membrane structure extending spike protein  Prognosis
