摘要:

目的 分析肾透明细胞癌(ccRCC)中蛋白质精氨酸甲基转移酶2(PRMT2)、肿瘤坏死因子受体相关因子2(TRAF2)的表达与转移相关基因的相关性及对预后的评估价值。方法 选取110例ccRCC患者,并检测其癌及癌旁组织PRMT2、TRAF2蛋白和mRNA表达,以及转移相关基因N-钙黏素(N-cad)、E-钙黏素(E-cad)、血管内皮生长因子A(VEGFA)、血管内皮生长因子C(VEGFC)mRNA表达。Pearson相关分析癌组织PRMT2、TRAF2 mRNA与转移相关基因 mRNA表达水平的相关性。分析PRMT2、TRAF2表达对ccRCC患者预后的影响。结果 ccRCC癌组织中PRMT2、TRAF2、N-cad、VEGFA、VEGFC mRNA表达量高于癌旁组织,E-cad mRNA表达量低于癌旁组织(P<0.01)。癌组织PRMT2、TRAF2 mRNA与N-cad、VEGFA、VEGFC mRNA表达呈正相关,与E-cad mRNA表达呈负相关(P<0.01)。ccRCC癌组织中PRMT2蛋白、TRAF2蛋白阳性率高于癌旁组织(P<0.01)。TNM分期Ⅲ期癌组织中PRMT2、TRAF2蛋白阳性率高于TNM分期Ⅰ—Ⅱ期癌组织(P<0.05)。PRMT2、TRAF2阳性组3年无进展生存率低于对应阴性组(P<0.05)。TNM分期Ⅲ期、PRMT2阳性、TRAF2阳性是影响ccRCC患者无进展生存预后的危险因素(P<0.05)。结论 ccRCC中PRMT2、TRAF2表达上调,与转移相关基因表达及肿瘤TNM分期有关,可作为评估ccRCC预后的标志物。

Abstract:

Objective To analyze the correlation between expression levels of protein arginine methyltransferase 2 (PRMT2), TNF receptor associated factor 2 (TRAF2) and metastasis-related genes in clear cell renal cell carcinoma (ccRCC)and their evaluation value for prognosis. Methods A total of 110 patients with ccRCC were selected. The expression levels of PRMT2, TRAF2 protein and mRNA, and the expression of metastasis-related genes [N-cadherin (N-cad), E-cadherin (E-cad), vascular endothelial growth factor A (VEGFA), vascular endothelial growth factor C (VEGFC)]were detected in cancer tissue and paracancer tissue. Pearson correlation analysis was used to analyze the correlation between PRMT2, TRAF2 mRNA and metastasis-related genes, and the effect of PRMT2 and TRAF2 expression on the prognosis of ccRCC patients. Results The mRNA expression levels of PRMT2, TRAF2, N-cad, VEGFA and VEGFC were higher in ccRCC cancer tissue than those in adjacent tissue, and E-cad was lower in ccRCC cancer tissue than that in adjacent tissue (P<0.01). PRMT2 and TRAF2 mRNA were positively correlated with N-cad, VEGFA and VEGFC mRNA expression, and negatively correlated with E-cad mRNA expression in cancer tissue (P<0.01). The positive rates of PRMT2 protein and TRAF2 protein in ccRCC cancer tissue were higher than those in adjacent tissue (P<0.01). The positive rates of PRMT2 and TRAF2 protein in TNM stage III cancer tissue were higher than those in TNM stage I-II cancer tissue (P < 0.05). The 3-year progression-free survival rate of the PRMT2 and TRAF2 positive group was lower than that of the negative group (P<0.05). TNM stage III, PRMT2 positive and TRAF2 positive were risk factors affecting the progression-free survival prognosis of ccRCC patients (P<0.05). Conclusion The expression levels of PRMT2 and TRAF2 are up-regulated in ccRCC, which are related to the expression of metastasis-related genes and TNM stage of tumor, and can be used as the marker for evaluating the prognosis of ccRCC.
