Long non-coding RNAs (lncRNAs) are hypothesized to regulate numerous biological behaviors in human cancers. The present study aimed to explore the roles of lncRNA bladder cancer associated transcript 1 (BLACAT1) in glioma. The expression of BLACAT1 in glioma tissues and cell lines was determined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). CCK-8 assay, colony formation assay, wound healing assay and Transwell invasion assay were used to explore the roles of BLACAT1 in glioma cells. RT-qPCR and western blot analysis were used to determine the BLACAT1 molecular mechanism. The findings demonstrated that lncRNA BLACAT1 was overexpressed in glioma tissues and cell lines. High BLACAT1 expression was correlated with high tumor grade in glioma patients. Functional assays determined that BLACAT1 promoted glioma cell proliferation, migration, invasion and epithelial-mesenchymal transition . In addition, it was demonstrated that BLACAT1 activated the Wnt/β-catenin signaling pathway. In conclusion, BLACAT1 may serve as an oncogenic lncRNA in glioma progression via activation of the Wnt/β-catenin signaling pathway. Therefore, BLACAT1 may be a novel therapeutic target for glioma treatment.
长链非编码RNA(lncRNAs)被认为可调节人类癌症中的多种生物学行为。本研究旨在探讨长链非编码RNA膀胱癌相关转录本1(BLACAT1)在胶质瘤中的作用。通过逆转录定量聚合酶链反应(RT-qPCR)检测BLACAT1在胶质瘤组织和细胞系中的表达。采用CCK-8法、集落形成试验、伤口愈合试验和Transwell侵袭试验探讨BLACAT1在胶质瘤细胞中的作用。采用RT-qPCR和蛋白质印迹分析确定BLACAT1的分子机制。研究结果表明,lncRNA BLACAT1在胶质瘤组织和细胞系中高表达。BLACAT1高表达与胶质瘤患者的高肿瘤分级相关。功能试验表明,BLACAT1促进胶质瘤细胞增殖、迁移、侵袭及上皮-间质转化。此外,研究表明BLACAT1激活Wnt/β-连环蛋白信号通路。总之,BLACAT1可能通过激活Wnt/β-连环蛋白信号通路在胶质瘤进展中作为一种致癌lncRNA。因此,BLACAT1可能是胶质瘤治疗的一个新的治疗靶点。
