ABSTRACT

Increasing studies suggested that long intergenic noncoding RNA 00511 (LINC00511) could facilitate the progression of various malignancies and correlates with prognosis of patients with malignant tumors. However, its clinical significance is still not completely clarified. Therefore, we performed a meta-analysis and bioinformatics analysis to further evaluate the correlation of LINC00511 expression level with prognosis and metastasis in patients with tumors. The pooled hazard ratio (HR) with 95% confidence interval (CI) was used to evaluate the prognostic significance of LINC00511 expression level. The pooled odds ratio (OR) with 95% CI was applied to assess the association between LINC00511 expression level and tumor metastasis. A total of 12 studies involving 1040 tumor patients were included in this meta-analysis. The pooled analyses suggested that higher LINC00511 expression level correlated with worse overall survival (OS) (HR = 1.93, 95% CI 1.49–2.49, P < 0.001) and higher incidence of lymph node metastasis (OR = 3.07, 95% CI 2.23–4.23, P < 0.001). Additionally, bioinformatics analysis based on TCGA datasets also showed that increased LINC00511 expression level may predict poor OS and disease-free survival (DFS) in patients with malignant tumors. Taken together, our finding suggested that high LINC00511 expression level may be correlated with poor prognosis and high incidence of metastasis. Nevertheless, further large-scale and high-quality studies are needed to validate our findings.

长基因间非编码RNA 00511在恶性肿瘤中的作用:荟萃分析,数据库验证和审查

摘要

越来越多的研究表明,较长的基因间非编码RNA 00511(LINC00511)可以促进各种恶性肿瘤的进展,并与恶性肿瘤患者的预后相关。但是,其临床意义仍未完全阐明。因此,我们进行了荟萃分析和生物信息学分析,以进一步评估LINC00511表达水平与肿瘤患者预后和转移的相关性。使用合并危险比(HR)和95%置信区间(CI)评估LINC00511表达水平的预后意义。应用具有95%CI的合并比值比(OR)评估LINC00511表达水平与肿瘤转移之间的关联。这项荟萃分析共包括12项研究,涉及1040例肿瘤患者。汇总分析表明,较高的LINC00511表达水平与较差的总生存率(OS)(HR = 1.93,95%CI 1.49–2.49,P <0.001)和较高的淋巴结转移发生率(OR = 3.07,95%CI 2.23–9)相关。 4.23,P <0.001)。此外,基于TCGA数据集的生物信息学分析还显示,LINC00511表达水平的提高可能预示着恶性肿瘤患者的OS差和无病生存(DFS)。两者合计,我们的发现表明,LINC00511高表达水平可能与不良预后和高转移发生率相关。然而,需要进一步的大规模和高质量的研究来验证我们的发现。001)和较高的淋巴结转移发生率(OR = 3.07,95%CI 2.23–4.23,P <0.001)。此外,基于TCGA数据集的生物信息学分析还显示,LINC00511表达水平的提高可能预示着恶性肿瘤患者的OS差和无病生存(DFS)。两者合计,我们的发现表明,LINC00511高表达水平可能与不良预后和高转移发生率相关。然而,需要进一步的大规模和高质量的研究来验证我们的发现。001)和较高的淋巴结转移发生率(OR = 3.07,95%CI 2.23–4.23,P <0.001)。此外,基于TCGA数据集的生物信息学分析还显示,LINC00511表达水平的提高可能预示着恶性肿瘤患者的OS差和无病生存(DFS)。两者合计,我们的发现表明,LINC00511高表达水平可能与不良预后和高转移发生率相关。然而,需要进一步的大规模和高质量的研究来验证我们的发现。我们的发现提示,LINC00511高表达可能与不良预后和高转移发生率相关。然而,需要进一步的大规模和高质量的研究来验证我们的发现。我们的发现提示,LINC00511高表达可能与不良预后和高转移发生率相关。然而,需要进一步的大规模和高质量的研究来验证我们的发现。
