目的研究肝X受体-β(Liver X receptor-β,LXR-β)和三磷酸腺苷结合盒转运子A1(ATP binding cassette transport protein A1,ABCA1)蛋白在人脑胶质母细胞瘤(Glioblastoma,GBM)中的表达及相关性,并探讨其对GBM的意义。方法分析48例GBM患者的资料,并取患者肿瘤组织石蜡切片,另取19份瘤旁正常脑组织石蜡切片为对照组,采用SP免疫组化法检测LXR-β和ABCA1蛋白的表达,并分析LXR-β与ABCA1表达的相关性。结果 LXR-β和ABCA1蛋白在GBM中的表达率分别为81.3%和77.1%,与对照组(15.8%和26.3%)相比,差异有统计学意义(P<0.001),且LXR-β与ABCA1的表达呈正相关(rs=0.500,P<0.05)。患者性别、年龄、胶质瘤复发、手术切除范围、肿瘤最大直径、术后放化疗情况与LXR-β、ABCA1蛋白的表达差异无统计学意义(P>0.05)。结论 LXR-β和ABCA1蛋白与GBM的形成和进展有一定关系,有可能成为临床诊断及治疗GBM的生物学指标。
【英文摘要】
Objective To investigate the expressions of liver X receptor-β(LXR-β)and ATP binding cassette transport protein A1(ABCA1) in human glioblastoma(GBM) and evaluate their relationship as well as their roles in GBM.Methods The clinical data on 48 cases of GBM were analyzed.The tumor tissues of patients were prepared into paraffin sections and determined for expressions of LXR-β and ABCA1 by immunohistochemical assay with SP staining,using 19 sections of normal brain tissue as control,based on which the relation...
