摘要

目的 探究长链非编码 RNA(lncRNA)ZNF30-3与微小核糖核酸-145-5′端(miR-145-5p)在前列腺癌(PCa)患者预后中的关系,为寻找灵敏度高、操作简便的PCa预后生物标志物提供参考。方法 选取2018年1月-2022年12月于徐州医科大学附属淮安医院行PCa根治性切除术的298例 PCa患者作为研究对象,另选取同期140例良性前列腺增生(BPH)患者为对照组。采用荧光定量聚合酶链式反应(PCR)法检测PCa组织、癌旁组织及 BPH 组织内lncRNA-ZNF30-3及 miR-145-5p的 mRNA 表达水平。分析PCa组织中lncRNA-ZNF30-3及 miR-145-5p的表达水平与PCa患者临床病理特征间的关系。随访截至2024年7月,绘制PCa患者的 Kaplan-Meier生存曲线。根据患者的预后情况将其分为预后良好组和预后不良组,经单因素、多因素 Cox回归分析影响PCa患者预后的相关因素。结果 lncRNA-ZNF30-3在PCa组织、癌旁组织及BPH 组织中的 mRNA 表达量分别为1.65±0.34、0.87±0.15、0.52±0.11,三组间差异有统计学意义(P<0.05)。miR-145-5p在PCa组织、癌旁组织及BPH 组织中 mRNA 表达量分别为0.78±0.17,1.54±0.21,2.13±0.25,三组间差异有统计学意义(P <0.05)。lncRNA-ZNF30-3 及 miR-145-5p的 mRNA 表达水平与 PCa患者的前列腺特异性抗原(PSA)水平、Gleason 评分以及淋巴结转移密切相关(P <0.05)。lncRNA-ZNF30-3高表达组PCa患者的总生存率低于lncRNA-ZNF30-3低表达组(73.58% vs. 89.52%,P=0.043);miR-145-5p高表达组PCa患者的总生存率高于 miR-145-5p低表达组(90.15% vs. 73.86%,P=0.028)。lncRNA-ZNF30-3的mRNA 相对表达水平上调,miR-145-5p的 mRNA 相对表达水平下调,Gleason评分≥7分,淋巴结转移PSA>20 ng/mL 是PCa患者预后不良的独立危险因素(均P<0.05)。结论 在PCa组织中lncRNA-ZNF30-3表达上调,miR-145-5p表达下调,并且二者均与PCa患者预后不良相关,可能是PCa患者术后预后评估的潜在分子标志物。

Abstract

Objective To explore the relationship between long non-coding RNA ZNF30-3(lncRNA-ZNF30-3)and 5′ end of microRNA-145(miR-145-5p)in the prognosis of prostate cancer(PCa),so as to provide reference for identifying sensitive and easy-to-operate prognostic biomarkers. Methods A total of 298 PCa patients who underwent radical prostatectomy at our hospital during Jan.2018 and Dec.2022 were selected as the study subjects,and another 140 patients with benign prostatic hyperplasia(BPH)during the same period were selected as the control group.The mRNA expressions of lncRNA-ZNF30-3 and miR-145-5p in PCa tissues,adjacent tissues and BPH tissues were detected with fluorescence quantitative polymerase chain reaction(PCR),and the expressions in PCa tissues and their relationship with the clinicopathological characteristics of PCa was analyzed.During the follow-up till Jul.2024,Kaplan-Meier survival curves of PCa patients were plotted.Based on the prognosis,the patients were divided into the good and poor prognosis groups.The related factors affecting the prognosis were analyzed with univariate and multivariate Cox regression. Results The mRNA expressions of lncRNA-ZNF30-3 in PCa tissues,adjacent cancer tissues and BPH tissues were 1.65±0.34,0.87±0.15 and 0.52±0.11,respectively,with a statistically significant difference (P<0.05).The mRNA expressions of miR-145-5p in PCa tissues,adjacent cancer tissues and BPH tissues were 0.78±0.17,1.54±0.21 and 2.13±0.25,respectively,with a statistically significant difference(P<0.05).The expressions of lncRNA-ZNF30-3 and miR-145-5p were closely related to the prostate-specific antigen(PSA)level,Gleason score,and lymph node metastasis of the patients(P<0.05).The overall survival rate of PCa patients with high expression of lncRNA-ZNF30-3 was lower than that of the patients with low expression(73.58% vs. 89.52%,P=0.043);the overall survival rate of PCa patients with high expression of miR-145-5p was higher than that of the patients with low expression(90.15% vs.73.86%,P=0.028).Upregulated expression of lncRNA-ZNF30-3,downregulated expression of miR-145-5p,Gleason score ≥7,lymph node metastasis,and PSA>20 ng/mL were independent risk factors for poor prognosis of PCa(all P<0.05). Conclusion In PCa tissues,the expression of lncRNA-ZNF30-3 is upregulated,while the expression of miR-145-5p is downregulated,and both are associated with poor prognosis.They may be potential molecular markers for postoperative prognosis assessment of PCa patients.
