Long noncoding RNAs have been proved in regulating tumourigenesis, including hepatocellular carcinoma (HCC). However, up to date, the role of PCAT6 in HCC is rare to be reported. In current study, bioinformatics analysis and quantitative real‐time PCR were applied to examine the expression of PCAT6 in HCC. The role of PCAT6 in cell proliferation, cell cycle arrest, apoptosis, and metastasis were detected in both gain‐ and loss‐of‐function studies by cell biological assays. Bioinformatics analysis was employed to investigate the PCAT6‐related genes and pathways in HCC. And we found that PCAT6 was significantly upregulated in HCC tissues and correlated with poor overall survival and disease‐free survival in HCC patients. Furthermore, elevated PCAT6 promoted cell proliferation, inhibited cell cycle arrest and cell apoptosis while deficiency of PCAT6 impaired cell proliferation, caused cell cycle arrest and induced cell apoptosis of HCC. Moreover, as for bioinformatics analysis, a total of 389 PCAT6‐related genes were found in both HCC tissue and cell lines, and these promising target genes were highly enriched in various key pathways, such as Wnt, HIF‐1 signalling pathway, and metabolic pathways. Additionally, among these genes, DCAF13, SNRPB2, RPS8, and FKBP1A were revealed to be overexpressed in HCC and predicted poor prognosis. Taken together, our findings illustrate that PCAT6 contributes to HCC progression and might be a potential target for HCC therapy. Bioinformatics analysis may present a new way for assessing the underlying mechanism of PCAT6 in HCC.

LncRNA PCAT6预测肝细胞癌的预后不良,并通过调节细胞周期停滞和凋亡促进增殖。

长期的非编码RNA已被证明可调节肿瘤发生,包括肝细胞癌(HCC)。然而,迄今为止,鲜有报道报道PCAT6在肝癌中的作用。在当前的研究中,生物信息学分析和定量实时PCR被用来检查PCAT6在肝癌中的表达。通过细胞生物学分析,在功能获得和丧失的研究中都检测到了PCAT6在细胞增殖,细胞周期停滞,凋亡和转移中的作用。利用生物信息学分析研究了肝癌中与PCAT6相关的基因和途径。而且,我们发现PCAT6在HCC组织中显着上调,并与HCC患者不良的总体生存率和无病生存率相关。此外,升高的PCAT6促进细胞增殖,PCAT6的缺乏会抑制细胞周期停滞和细胞凋亡,而PCAT6缺乏会损害细胞增殖,导致细胞周期停滞并诱导HCC细胞凋亡。此外,就生物信息学分析而言,在HCC组织和细胞系中共发现389个PCAT6相关基因,这些有希望的靶基因在Wnt,HIF-1信号通路和代谢等各种关键途径中高度富集。途径。此外,在这些基因中,DCAF13,SNRPB2,RPS8和FKBP1A在HCC中被发现过表达,并预示不良预后。综上所述,我们的发现表明PCAT6有助于肝癌的进展,并且可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。导致肝癌细胞周期停滞并诱导细胞凋亡。此外,就生物信息学分析而言,在HCC组织和细胞系中共发现389个PCAT6相关基因,这些有希望的靶基因在Wnt,HIF-1信号通路和代谢等各种关键途径中高度富集。途径。此外,在这些基因中,DCAF13,SNRPB2,RPS8和FKBP1A在HCC中被过度表达,并预示不良预后。综上所述,我们的发现表明PCAT6有助于肝癌的进展,并且可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。导致肝癌细胞周期停滞并诱导细胞凋亡。此外,就生物信息学分析而言,在HCC组织和细胞系中共发现389个PCAT6相关基因,这些有希望的靶基因在Wnt,HIF-1信号通路和代谢等各种关键途径中高度富集。途径。此外,在这些基因中,DCAF13,SNRPB2,RPS8和FKBP1A在HCC中被过度表达,并预示不良预后。综上所述,我们的发现表明PCAT6有助于肝癌的进展,并且可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。这些有希望的靶基因在Wnt,HIF-1信号传导途径和代谢途径等各种关键途径中高度富集。此外,在这些基因中,DCAF13,SNRPB2,RPS8和FKBP1A在HCC中被发现过表达,并预示不良预后。综上所述,我们的发现表明PCAT6有助于肝癌的进展,并且可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。这些有希望的靶基因在Wnt,HIF-1信号传导途径和代谢途径等各种关键途径中高度富集。此外,在这些基因中,DCAF13,SNRPB2,RPS8和FKBP1A在HCC中被发现过表达,并预示不良预后。综上所述,我们的发现表明PCAT6有助于肝癌的进展,并且可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。我们的发现表明,PCAT6有助于肝癌的进展,可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。我们的发现表明,PCAT6有助于肝癌的进展,可能是肝癌治疗的潜在靶标。生物信息学分析可能为评估HCC中PCAT6的潜在机制提供了一种新方法。
