摘要: 目的: 探讨Chemerin对口腔鳞癌(OSCC)组织中性粒细胞浸润的影响及其可能的分子机制。方法: 应用免疫组织化学双染色方法,探讨中性粒细胞浸润与Chemerin表达之间的关系。利用Transwell实验、实时定量PCR(qRT-PCR)、蛋白质印迹法(Western blot)、酶联免疫吸附法(ELISA)和流式细胞术检测Chemerin对中性粒细胞的趋化作用。采用SPSS 23.0软件包对数据进行统计学分析。Chemerin表达和中性粒细胞密度之间的关系采用Spearman等级相关分析法,ChemR23的敲除效率、趋化指数的计算采用方差分析,Chemerin表达和中性粒细胞密度与临床病理因素的关系采用Mann-Whitney检验,生存分析采用Kaplan-Meier法和Log rank检验,OSCC生存的危险因素采用Cox回归模型。结果: 免疫组织化学双染色结果显示,Chemerin高表达与口腔鳞癌组织内中性粒细胞浸润密度呈正相关(P=0.023),Chemerin高表达且中性粒细胞高密度与临床分期(P<0.001)、颈淋巴结转移(P<0.001)和肿瘤复发相关(P=0.002)。Kaplan-Meier生存分析表明,Chemerin高表达且中性粒细胞高密度组患者较其他2组的癌症相关总体生存期和无瘤生存期显著缩短。Transwell结果显示,OSCC 细胞和重组Chemerin对dHL-60细胞有明显趋化作用;敲除dHL-60细胞上的ChemR23后,抑制了Chemerin对dHL-60细胞的趋化作用。结论: 口腔鳞癌组织中Chemerin过表达,可通过受体ChemR23,趋化更多中性粒细胞浸润且与不良临床预后有关。

Abstract: PURPOSE: To explore the effect of Chemerin in oral squamous cell carcinoma (OSCC) tissue on neutrophils infiltration and its possible molecular mechanism. METHODS: The relationship between Chemerin expression and neutrophils density was assessed via double immunohistochemistry staining.The chemotactic effect of Chemerin on neutrophils in OSCC was detected by transwell assay, real-time quantitative PCR(qRT-PCR), Western blot, enzyme-linked immunosorbent assay(ELISA) and flow cytometry. The data were statistically analyzed using SPSS 23.0 software package. The relationship between Chemerin expression and neutrophils density was assessed using Spearman rank correlation analysis. ChemR23 knockout efficiency and chemotactic index were calculated by ANOVA. The relationship between Chemerin expression, neutrophils density and clinicopathological factors was analyzed by Mann-Whitney test. Kaplan-Meier test and Log rank test were used for survival analysis, and risk factors affecting the survival of OSCC patients was assessed using Cox regression model. RESULTS: Double immunohistochemistry staining showed that overexpression of Chemerin was significantly correlated with increased neutrophils infiltration in OSCC(P=0.023), and strong Chemerin expression and high neutrophils density were associated with higher clinical stage(P<0.001), cervical lymph node metastasis (P<0.001) and tumor recurrence (P=0.002). Kaplan-Meier survival analysis showed that patients in the strong Chemerin expression + high neutrophils density group had shortened cancer-related overall survival time and disease-free survival time compared with the other two groups. Transwell assay results showed that both OSCC cells and R-Chemerin had a significant chemotactic effect on dHL-60 cells; knockdown of ChemR23 suppressed Chemerin-induced chemotaxis to dHL-60 cells. CONCLUSIONS: Overexpression of Chemerin in OSCC tissue chemoattracts more neutrophils to tumor sites through its receptor ChemR23 and is related to poor clinical prognosis.
