摘    要:目的 分析SLP-76基因在食管癌、贲门癌、胃癌、结肠癌及其癌旁组织中的差异表达。方法 依据微阵列技术筛选出SLP-76基因在食管癌组织中高表达的结果,应用逆转录-聚合酶链式反应(RT-PCR),对上述消化道肿瘤组织及其癌旁组织中的SLP-76基因表达进行检测。结果 SLP-76在73.3%(22/30)的食管癌组织中高表达(P=0.005):在75%(9/12)的贲门癌组织中高表达(P=0.014);在75%(12/16)胃癌组织中高表达(P=0.005);在72.2%(13/18)结肠癌组织中高表达(P=0.008)。结论 在RNA水平,SLP-76基因在上述肿瘤之间的表达无显著性差异(P=0.9684)。但该基因在消化道肿瘤中高表达,SLP-76与上述消化道肿瘤生长关系密切;可能具有潜在的致癌性。

关 键 词:SLP-76基因  消化道肿瘤  基因表达  微阵列技术  RT-PCR

Abstract:Objective Confirm the microarray hybridization results and examine the expression of SLP-76 gene in digestive tract cancers and adjacent normal mucosa.MethodsAccording to analysis results of microarray, distinctly differential ly expressed SLP-76 gene was screening out. RT-PCR was applied to check the expression o f SLP-76 in digestive tract cancers and adjacent normal mucosa. ResultsBy RT-PCR examination ,we found that SLP-76 gene over expression in cancer of the digestive tract. ConclusionsDifferent expression of SLP-76 gene in cancer of the digestive tract is found, SLP-76 gene have closely relation with grown in the cancer of digestive tract.It is apossibly potential oncology gene in the cancer of digestive tract. This differential expressio n appeared no tissue specificity with statistical analysis (P=0.9684).
Keywords:Digestive tract cancers  SLP-76 gene  Different expression
