目的 探究miR-7-5p/FGFR4轴与胆囊癌(gall bladder cancer,GBC)患者预后的关系。方法 选取武警特色医学中心2016-06至2018-06住院手术的GBC患者47例,收集胆囊癌组织(GBC组)及癌旁组织(PCLT组),选择同期良性胆囊疾病患者43例,收集良性胆囊组织(NC组),用RT-qPCR检测组织标本中成纤维生长因子受体4(fibroblast growth factor receptor 4,FGFR4)和miR-7-5p mRNA水平,并随访患者术后生存情况;分析miR-7-5p与FGFR4 mRNA表达水平的关系,根据miR-7-5p、FGFR4表达水平分为低表达亚组和高表达亚组,并分析其与胆囊癌患者预后的关系。结果 与PCLT组和NC组比较,GBC组miR-7-5p mRNA表达水平明显下降,FGFR4 mRNA水平明显升高,差异有统计学意义(P<0.01);PCLT组和NC组比较,miR-7-5p mRNA表达水平下降,FGFR4 mRNA水平升高,但差异无统计学意义(P>0.05);miR-7-5p mRNA表达水平与FGFR4 mRNA表达水平负相关(r=-0.535,P=0.004);miR-7-5p mRNA表达水平与胆囊癌的分期、分化程度和淋巴转移情况相关(P=0.035,P=0.036,P=0.006),miR-7-5p mRNA低表达亚组患者生存率低于高表达亚组(P=0.047),FGFR4 mRNA低表达亚组生存率高于高表达亚组(P=0.033)。结论 miR-7-5p/FGFR4轴可能是影响GBC预后的指标之一。
Abstract
Objective To explore the relationship between the miR-7-5p/FGFR4 axis and the prognosis of patients with gallbladder cancer (GBC).Methods A total of 47 GBC patients who underwent surgery in the Characteristic Medical Center of PAP between June 2016 and June 2018 were enrolled, whose gallbladder cancer tissues (GBC group) and paracancerous tissues (PCLT group) were collected. Another 43 patients with benign gallbladder disease were selected, and their benign gallbladder tissues were collected as the control group (NC group). The mRNA levels of fibroblast growth factor receptor 4 (FGFR4) and miR-7-5p were detected by RT-qPCR. The postoperative survival was followed up. The relationship between miR-7-5p and FGFR4 mRNA expressions was analyzed. According to the expression levels of miR-7-5p or FGFR4, these patients were divided into the low expression subgroup and high expression subgroup, and the relationship between the these expression levels and the prognosis of patients with gallbladder cancer was analyzed respectively.Results Compared with the PCLT or NC group, the level of miR-7-5p mRNA in the GBC group decreased, but the level of FGFR4 mRNA increased, and the difference was statistically significant (P<0.01). When compared with the NC group, the expression level of miR-7-5p mRNA in the PCLT group decreased, while the level of FGFR4 mRNA increased, but the difference was not statistically significant (P>0.05). The expression level of miR-7-5p mRNA was negatively correlated with that of FGFR4 mRNA (r=-0.535, P=0.004). The expression level of miR-7-5p mRNA was correlated with the stage, degree of differentiation and lymphatic metastasis of gallbladder carcinoma (P=0.035, P=0.036, P=0.006). The survival rate of patients in the miR-7-5p mRNA low expression subgroup was lower than that of the high expression subgroup (P=0.047), but that of patients in the FGFR4 mRNA low expression subgroup was higher than in the high expression subgroup (P=0.033).Conclusions The miR-7-5p/FGFR4 axis may be one of the indicators that affects the prognosis of GBC.
