摘要:

目的:探讨泛素样含PHD和环指域1(UHRF1)蛋白在结直肠癌中的表达及其预后判断价值。方法:采用组织微阵列联合免疫组织化学(TMA-IHC)技术检测201例结直肠癌中UHRF1蛋白的表达情况,分析其与临床病理指标及术后生存时间之间的相关性。结果:UHRF1蛋白在结直肠癌组织中的表达阳性率为54.2%(109/201),显著高于配对的手术切端形态学正常的组织(P<0.01)。Kaplan-Meier生存分析显示,UHRF1蛋白表达阳性患者术后生存时间短于表达阴性的患者(P=0.023)。Cox回归分析结果表明,UHRF1蛋白是结直肠癌患者根治术后的一个独立预后因素(P=0.008)。结论:UHRF1蛋白可能作为结直肠癌患者术后预后判断的分子标志。

Abstract:

OBJECTIVE: This study aimed to evaluate the expression and prognostic significance of ubiquitin-like with PHD and ring finger domains 1 (UHRF1) protein in colorectal cancer (CRC). METHODS:The expression of UHRF1 in 201 CRC cases and adjacent normal tissues were detected by tissue microarrays and immunohistochemistry (TMA-IHC),then the relationship between UHRF1 protein expression and clinio-pathological parameters as well as its prognostic value were examined by statistical analysis. RESULTS:Positive expression of UHRF1 was observed in 54.2% (109/201) of CRC tissues,and the frequency in CRC was significantly higher than that in adjacent nomal tissues (P<0.01). Kaplan-Meier survival curves showed that CRC patients with negative expression of UHRF1 had shorter overall survival time (P=0.023). Cox regression analysis indicated that UHRF1 protein expression was an independent prognostic factor (P=0.008). CONCLUSION:UHRF1 might be a biomarker for prognostic evaluation of CRC patients.
