HOXC cluster antisense RNA 3 (HOXC-AS3) is a long noncoding RNA (lncRNA) that plays a crucial role in various tumors; nevertheless, its role in glioma and its mechanism have not been completely elucidated. In this research, we discovered that HOXC-AS3 was over-expression in glioma cells and tissues and was associated with prognosis. Next, we determined that HOXC-AS3 targeted miR-216 as a sponge and that the F11 receptor (F11R) was the target of miR-216 by online databases analysis, qRT-PCR, and luciferase reporter assay. In addition, the rescue experiments confirmed that HOXC-AS3 regulated the expression of F11R by competitively binding miR-216 and functioning as a competing endogenous RNA (ceRNA). The intracranial glioblastoma mouse model suggested that HOXC-AS3 could promote glioma malignant progression . In summary, our study shows that the HOXC-AS3/miR-216/F11R axis plays an important role in the malignant progression of glioma, and may provide new ideas for the treatment of glioma.
HOXC簇反义RNA 3(HOXC-AS3)是一种长链非编码RNA(lncRNA),在多种肿瘤中发挥关键作用;然而,其在胶质瘤中的作用及其机制尚未完全阐明。在本研究中,我们发现HOXC-AS3在胶质瘤细胞和组织中高表达,且与预后相关。接下来,通过在线数据库分析、qRT-PCR和荧光素酶报告基因检测,我们确定HOXC-AS3作为海绵靶向miR-216,且F11受体(F11R)是miR-216的靶标。此外,拯救实验证实HOXC-AS3通过竞争性结合miR-216并作为竞争性内源RNA(ceRNA)发挥作用,从而调节F11R的表达。颅内胶质母细胞瘤小鼠模型表明HOXC-AS3可促进胶质瘤的恶性进展。总之,我们的研究表明HOXC-AS3/miR-216/F11R轴在胶质瘤的恶性进展中起重要作用,可能为胶质瘤的治疗提供新思路。
