Long non‑coding RNAs (lncRNAs) can act as carcinogenic or cancer suppressive factors during the pathogenesis, invasion and metastasis of non‑small cell lung cancer (NSCLC). The current study explored the role of long intergenic non‑protein coding RNA 00887 (LINC00887) and competing endogenous RNAs (ceRNAs). It was revealed that LINC00887 interacts with several microRNAs (miRs), which regulates downstream genes such as fibronectin 1, MET proto‑oncogene, receptor tyrosine kinase and mothers against decapentaplegic homolog 4, which are associated with the spread of lung cancer. The experimental results also suggested that LINC00887 can stimulate miR‑613, miR‑206 and miR‑1‑2 to become competing endogenous RNAs, which may regulate the epithelial‑mesenchymal transition of NSCLC cells through the transforming growth factor‑â signal transduction pathway, and therefore promote the migration of cells and the acquisition of stem cell characteristics. Therefore, it can be concluded that high levels of LINC00887 can accelerate the malignant transformation ability of NSCLC cells.
长非编码 RNA(lncRNA)可在非小细胞肺癌(NSCLC)的发病机制、侵袭和转移过程中充当致癌或抑癌因子。本研究探讨了长链非编码 RNA 00887(LINC00887)和竞争性内源 RNA(ceRNA)的作用。结果表明,LINC00887 与几种 microRNA(miR)相互作用,调节下游基因,如纤维连接蛋白 1、原癌基因 MET 受体酪氨酸激酶和母体对抗 decapentaplegic 同源物 4,这些基因与肺癌的扩散有关。实验结果还表明,LINC00887 可以刺激 miR-613、miR-206 和 miR-1-2 成为竞争性内源 RNA,通过转化生长因子-α信号转导通路可能调节 NSCLC 细胞的上皮-间充质转化,从而促进细胞迁移和获得干细胞特性。因此,可以得出结论,高水平的 LINC00887 可以加速 NSCLC 细胞的恶性转化能力。
