Lung adenocarcinoma (LUAD) is the most common histological lung cancer, and it is the leading cause of cancer-related deaths worldwide. Long noncoding RNAs (lncRNAs) have been implicated in the initiation and progression of various cancers. LncRNA-AC099850.3 is a novel lncRNA that is abnormally expressed in diverse cancer types including LUAD. However, the clinical significance, prognostic value, diagnostic value, immune role, and potential biological function of AC099850.3 LUAD remain elusive. In this study, we found that AC099850.3 was highly expressed in LUAD and associated with an advanced tumor stage, poor prognosis, and immune infiltration. Receiver operating curve analysis revealed the significant diagnostic ability of AC099850.3 (AUC=0.888). Functionally, the knockdown of AC099850.3 restrained LUAD cell proliferation and migration . Finally, we constructed a competitive endogenous RNAs (ceRNA) network that included hsa-miR-101-3p and 4 mRNAs (ESPL1, AURKB, BUB3, and FAM83D) specific to AC099850.3 in LUAD. Kaplan-Meier survival analysis showed that a lower expression of miR-101-3p and a higher expression of ESPL1, AURKB, BUB3, and FAM83D, were associated with adverse clinical outcomes in patients with LUAD. This finding provided a comprehensive view of the AC099850.3-mediated ceRNA network in LUAD, thereby highlighting its potential role in the diagnosis and prognosis of LUAD.
肺腺癌(LUAD)是最常见的组织学类型肺癌,也是全球癌症相关死亡的主要原因。长链非编码RNA(lncRNAs)已被证明与多种癌症的发生和发展有关。LncRNA-AC099850.3是一种新型lncRNA,在包括LUAD在内的多种癌症类型中异常表达。然而,AC099850.3在LUAD中的临床意义、预后价值、诊断价值、免疫作用及潜在生物学功能仍不清楚。在本研究中,我们发现AC099850.3在LUAD中高表达,且与肿瘤晚期、预后不良及免疫浸润相关。受试者工作特征曲线分析显示AC099850.3具有显著的诊断能力(AUC=0.888)。功能上,敲低AC099850.3可抑制LUAD细胞增殖和迁移。最后,我们构建了一个竞争性内源性RNA(ceRNA)网络,该网络包含hsa-miR-101-3p和4种LUAD中AC099850.3特异的mRNA(ESPL1、AURKB、BUB3和FAM83D)。Kaplan-Meier生存分析表明,miR-101-3p低表达以及ESPL1、AURKB、BUB3和FAM83D高表达与LUAD患者不良临床结局相关。这一发现全面揭示了LUAD中AC099850.3介导的ceRNA网络,从而突出了其在LUAD诊断和预后中的潜在作用。
