摘要: 目的 探讨大肠癌组织中单ADP核糖基转移酶ART1的表达与VEGF、整合素αVβ3表达的相关性及其对大肠癌组织微血管生成的影响。方法 免疫组化检测大肠癌组织中ART1、VEGF及整合素αVβ3的表达;免疫荧光双标检测ART1/VEGF及ART1/整合素αVβ3的共表达,用Chalkley分析法评估微血管的形成。结果 ART1、VEGF与整合素αVβ3的表达高于对照组(P

Abstract: Abstract:Objective To study correlation of the ART1 expression with VEGF and Integrin αVβ3 expression and the affection of ART1 to mieroangiogenesis in colorectal carcinoma.Methods Immunohistochemical be used to detect the expression of ART1, VEGF and Integrin αVβ3, and immunofluorescence double staining be used to detect co- expression of ART1/ VEGF and ART1/Integrin αVβ3;and the microvascular density(MVD) quantified by Chalkley analysis Results The expression of ART1,VEGF and integrin αVβ3 was significantly higher than in control group(P<0.05) ,and there is a positive correlation of ART1 with VEGF and Integrin αVβ3.The group of co-expression of ART1/ VEGF and Integrin αVβ3 show higher microvessel density(25.4±8.23,22.3±5.9) than the group of non-co-expression group(5.5±2.0和8.1±3.3,P
