摘　　要：目的探究环状RNA(circular RNAs,circRNAs)hsa_circ_0003922在子宫内膜样癌(endome⁃trioid carcinoma,EEC)中的表达及其临床意义。方法选取3例EEC组织及3例正常子宫内膜组织进行高通量分子测序,筛选出特异性circRNAs及相关功能分子。另选取EEC患者36例为观察组,子宫良性病变患者36例为对照组,选定表达差异大的hsa_circ_0003922作为研究对象,通过实时荧光定量PCR(RTqPCR)检测其在EEC组织及对照组中的表达,分析其表达量与EEC临床病理特征之间的关系。并预测与hsa_circ_0003922结合的miRNAs。采用受试者工作特征曲线(ROC)分析hsa_circ_0003922对EEC的阳性诊断价值。结果高通量分子测序结果显示,与对照组相比,EEC组织中差异表达的circRNAs有293个,其中115个高表达,178个低表达;RT-qPCR检测进一步发现,hsa_circ_0003922在EEC组织中的表达较对照组明显降低(P<0.05);hsa_circ_0003922的表达水平与EEC的FIGO分期和组织学分级呈明显负相关(P<0.05);hsa_circ_0003922在两组患者中对于EEC诊断阳性的ROC曲线的AUC为0.7724(P<0.05)。结论hsa_circ_0003922的表达与EEC的FIGO分期和组织学分级相关,有可能成为EEC辅助诊断、评估预后的参考指标及辅助治疗的潜在分子靶点。Objective Investigation of the expression and clinical significance of circular RNA hsa_circ_0003922 in endometrioid carcinoma(EEC).Methods Three EEC tissues and three normal endometrial tissues were selected for high-throughput molecular sequencing to identify specific circRNAs and related functional molecules.Additionally,36 EEC patients were selected as the experimental group,while 36 patients with benign uterine lesions served as the control group.The differentially expressed hsa_circ_0003922 was chosen as the research target,and its expression in EEC tissues and the control group was detected using real-time fluorescence quantitative PCR(RT-qPCR).The relationship between its expression level and clinical pathological features of EEC was analyzed.Furthermore,the miRNAs associated with hsa_circ_0003922 were predicted.The receiver operating characteristic(ROC)curve analysis was employed to evaluate the diagnostic value of hsa_circ_0003922 for EEC.Results The results of high-throughput molecular sequencing showed that there were 293 differentially expressed circRNAs in EEC tissues compared to the control group,including 115 upregulated and 178 downregulated circRNAs.RT-qPCR further revealed that the expression of hsa_circ_0003922 was significantly decreased in EEC tissues compared to the control group(P<0.05).The expression level of hsa_circ_0003922 was significantly negatively correlated with FIGO staging and histological grading of EEC(P<0.05).The area under the ROC curve(AUC)for hsa_circ_0003922 in distinguishing EEC patients from the control group was 0.7724(P<0.05).Conclusion The expres⁃sion of hsa_circ_0003922 is associated with FIGO staging and histological grading of EEC,indicating its potential as a reference index for auxiliary diagnosis,prognosis evaluation,and as a potential molecular target for adjuvant therapy in EEC.
