Long non-coding RNAs (lncRNAs) have played crucial roles in various cancers, including nasopharyngeal carcinoma (NPC). In our study, we focused on the biological function and clinical significance of lncRNA LINC00460 in NPC. It was indicated that LINC00460 was markedly increased in NPC tissues and cells compared to their corresponding controls. Silencing LINC00460 was able to suppress NPC cell growth in vitro while overexpressing LINC00460 reversed this process. Moreover, in vivo tumor xenografts were established using CNE-1/SUNE-1 cells to detect the function of LINC00460 in NSCLC tumorigenesis. Rescue assay was performed to further confirm that LINC00460 contributed to the progression of NPC through regulating miR-149-5p/IL6 signal pathway. In conclusion, we have uncovered that LINC00460 could be regarded as a novel prognostic biomarker and therapeutic target in NPC diagnosis and treatment.
长链非编码RNA(lncRNAs)在包括鼻咽癌(NPC)在内的多种癌症中发挥了关键作用。在我们的研究中,我们聚焦于lncRNA LINC00460在鼻咽癌中的生物学功能和临床意义。结果表明,与相应对照相比,LINC00460在鼻咽癌组织和细胞中显著上调。沉默LINC00460能够在体外抑制鼻咽癌细胞生长,而过表达LINC00460则逆转了这一过程。此外,利用CNE-1/SUNE-1细胞建立体内肿瘤异种移植模型,以检测LINC00460在鼻咽癌肿瘤发生中的功能。进行了挽救实验以进一步证实LINC00460通过调节miR-149-5p/IL6信号通路促进鼻咽癌的进展。总之,我们发现LINC00460可被视为鼻咽癌诊断和治疗中的一种新型预后生物标志物和治疗靶点。
