摘要:

目的 分析肝癌和肝硬化患者肝组织中肿瘤坏死因子α诱导蛋白8样分子2(tumor necrosis factor-α-induced protein 8-like 2,TIPE2)和FOXP3 mRNA及蛋白的表达情况,探讨TIPE2和FOXP3在肝硬化和肝癌发生发展中的作用。方法 收集肝癌和肝硬化患者手术切除的肝组织60例,分别应用免疫组化法和RT-PCR法检测肝组织中TIPE2和FOXP3 mRNA及蛋白的表达水平,并与肝组织病理分级、甲胎蛋白(alpha-fetoprotein,AFP)、天冬氨酸氨基转移酶(aspartate transaminase, AST)/丙氨酸氨基转移酶(alanine amiotransferase, ALT)比值、中性粒细胞/淋巴细胞比值(neutrophil-to-lymphocyte ratio,NLR)等多项临床资料进行相关性分析。结果 肝癌患者较肝硬化患者肝组织中TIPE2 mRNA和蛋白表达明显降低(P<0.01),而FOXP3 mRNA和蛋白表达明显升高(P<0.01);肝组织TIPE2蛋白和mRNA表达水平与FOXP3表达水平呈负相关(P<0.05,P<0.01);TIPE2和FOXP3表达与肝癌组织分化程度密切相关,分化程度越低TIPE2下调越明显,而FOXP3上调越显著;同时TIPE2表达程度与血清AFP水平、AST/ALT比值、中性粒细胞数量和NLR呈负相关。结论 TIPE2可能通过负性调控FOXP3+Treg细胞介导的免疫反应参与了肝脏疾病的发生和进展,在肝癌的发生中可能发挥负性调控作用。

Abstract:

Objective To detect the mRNA and protein levels of tumor necrosis factor-α-induced protein 8-like 2 (TIPE2) and FOXP3 in patients with cirrhosis and hepatocellular carcinoma (HCC) and their clinical significances. Methods A total of 60 surgical specimens from patients with HCC and cirrhosis were enrolled. The expression levels of TIPE2 and FOXP3 in liver tissues were evaluated using immunohistochemistry and real-time reverse transcription-polymerase chain reaction (RT-PCR). The correlation of TIPE2 and FOXP3 levels with pathological grading, alpha-fetoprotein (AFP), aspartate transaminase/alanine aminotransferase (AST/ALT), neutrophil-to-lymphocyte ratio (NLR) and other clinical data was analyzed. Results The mRNA and protein levels of TIPE2 were significantly down-regulated (P<0.01), while those of FOXP3 were significantly up-regulated in HCC tissues compared to cirrhosis tissues (P<0.01). Importantly, the mRNA and protein levels of TIPE2 were negatively correlated with FOXP3 expressions (P<0.05 and P<0.01, respectively). Furthermore, TIPE2 and FOXP3 levels were correlated with pathological grade of HCC tissue, and lower TIPE2 and higher FOXP3 levels indicated lower differentiation level. TIPE2 expression was negatively correlated with the AFP level, AST/ALT ratio, neutrophil count and neutrophil-to-lymphocyte ratio (NLR). Conclusion TIPE2 is involved in the liver diseases by negatively regulating the function of FOXP3+ Tregs-induced immune response, and negatively participates in the occurrence of HCC.
