摘要

非编码小RNA，特别是trna衍生的小RNA (tsrna)，在癌症患者中很容易检测到，表现出显著的稳定性，并且存在高丰度。它们在肿瘤发展中起着重要作用。然而，血清tsRNAs在肝细胞癌（HCC）中的临床意义仍然知之甚少。在本研究中，我们探讨了一种名为tRF-23-R9J89O9N9的新型tsRNA在HCC的辅助诊断、疾病监测和预后评估中的作用。方法通过筛选the Cancer Genome Atlas（TCGA）数据库，确定tRF-23-R9J89O9N9为靶标分子。采用qRT-PCR检测其表达水平。采用琼脂糖凝胶电泳、Sanger测序、梯度稀释实验、室温稳定性试验、反复冻融评价等方法评价tRF-23-R9J89O9N9的性能。采用χ2检验分析tRF-23-R9J89O9N9水平与临床病理参数的相关性。采用ROC曲线分析评价tRF-23-R9J89O9N9对HCC的诊断价值，采用Kaplan-Meier曲线评价预后价值。结果HCC患者血清中tRF-23-R9J89O9N9表达水平显著升高，术后患者血清中tRF-23-R9J89O9N9表达水平恢复到正常水平。此外，tRF-23-R9J89O9N9的表达与TNM分期（P = 0.009）、淋巴结转移（P<0.0001）、分化程度（P<0.0001）相关。此外，AFP、PIVKA-II和CEA联合检测，大大提高了对HCC的诊断价值。血清tRF-23-R9J89O9N9也被确定为HCC动态监测和预后的潜在生物标志物。结论strf -23- r9j89o9n9可能是一种潜在的肝癌辅助诊断的新型生物标志物。

tRF-23-R9J89O9N9:A novel liquid biopsy marker for diagnosis of hepatocellular carcinoma

Background

Non-coding small RNA, specifically tRNA-derived small RNAs (tsRNAs), are readily detectable in cancer patients, exhibit remarkable stability, and are present in high abundance. They play a significant role in tumor development. However, the clinical significance of serum tsRNAs in hepatocellular carcinoma (HCC) remains poorly understood. In this study, we explored the impact of a novel tsRNA, named tRF-23-R9J89O9N9, in the adjuvant diagnosis, disease monitoring, and prognosis assessment of HCC.

Methods

The tRF-23-R9J89O9N9 was identified as the target molecule through screening the The Cancer Genome Atlas(TCGA) database. Its expression levels were measured using qRT-PCR. Various methods, including agarose gel electrophoresis, Sanger sequencing, gradient dilution experiments, room temperature stability tests, and repeated freeze–thaw assessments, were employed to evaluate the performance of tRF-23-R9J89O9N9. The correlation between tRF-23-R9J89O9N9 levels and clinicopathological parameters was analyzed using the χ² test. The diagnostic value of tRF-23-R9J89O9N9 in HCC was assessed with ROC curve analysis, while the prognostic value was evaluated using Kaplan-Meier curves.

Results

Serum tRF-23-R9J89O9N9 expression levels were significantly elevated in HCC patients, while levels in postoperative patients were restored to those of healthy subjects. Additionally, the expression of tRF-23-R9J89O9N9 related to TNM stage(P = 0.009), lymph node metastasis(P＜0.0001), and degree of differentiation(P＜0.0001). Furthermore, the combination of AFP, PIVKA-II, and CEA greatly improved the diagnostic value for HCC. Serum tRF-23-R9J89O9N9 was also identified as a potential biomarker for dynamic monitoring and prognosis of HCC.

Conclusions

tRF-23-R9J89O9N9 may regard as a potential novel biomarker for the adjuvant diagnosis of HCC.

期刊介绍： The Official Journal of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Clinica Chimica Acta is a high-quality journal which publishes original Research Communications in the field of clinical chemistry and laboratory medicine, defined as the diagnostic application of chemistry, biochemistry, immunochemistry, biochemical aspects of hematology, toxicology, and molecular biology to the study of human disease in body fluids and cells. The objective of the journal is to publish novel information leading to a better understanding of biological mechanisms of human diseases, their prevention, diagnosis, and patient management. Reports of an applied clinical character are also welcome. Papers concerned with normal metabolic processes or with constituents of normal cells or body fluids, such as reports of experimental or clinical studies in animals, are only considered when they are clearly and directly relevant to human disease. Evaluation of commercial products have a low priority for publication, unless they are novel or represent a technological breakthrough. Studies dealing with effects of drugs and natural products and studies dealing with the redox status in various diseases are not within the journal''s scope. Development and evaluation of novel analytical methodologies where applicable to diagnostic clinical chemistry and laboratory medicine, including point-of-care testing, and topics on laboratory management and informatics will also be considered. Studies focused on emerging diagnostic technologies and (big) data analysis procedures including digitalization, mobile Health, and artificial Intelligence applied to Laboratory Medicine are also of interest.
