Long non-coding RNA (lncRNA) HAND2-AS1 has been indicated to play biological roles in several cancers. However, whether HAND2-AS1 could exert its role in glioma remains unknown. We aimed to investigate the function of HAND2-AS1 in the proliferation, invasion and migration and to explore its underlying molecular mechanism in glioma cells.
Reverse transcription-quantitative polymerase chain reaction analysis was conducted to determine the expression of HAND2-AS1 and cyclin-dependent kinases 6 (CDK6) in tissues or cells. Western blot analysis was used to detect the CDK6 protein expression. CCK-8 assay was adopted to determine the proliferation in glioma cell lines. Transwell assay was taken to evaluate the invasion and migration in glioma cell lines.
Our results revealed that HAND2-AS1 expression was significantly downregulated in the glioma tissues and cell lines. Moreover, overexpression of HAND2-AS1 attenuated the proliferation, invasion, and migration in glioma cell lines. However, overexpression of CDK6 could partially block the inhibitory role of HAND2-AS1 on cell proliferation as well as cell invasion and migration in glioma cell lines.
LncRNA HAND2-AS1 may play a critical anti-tumorigenic role in glioma by negatively regulating CDK6 expression.
长链非编码 RNA(lncRNA)HAND2-AS1 在几种癌症中发挥着重要的生物学作用。然而,HAND2-AS1 是否能在神经胶质瘤中发挥作用尚不清楚。本研究旨在探讨 HAND2-AS1 在神经胶质瘤细胞中的增殖、侵袭和迁移中的作用,并探讨其潜在的分子机制。
采用逆转录定量聚合酶链反应分析组织或细胞中 HAND2-AS1 和细胞周期蛋白依赖性激酶 6(CDK6)的表达。采用 Western blot 分析检测 CDK6 蛋白表达。采用 CCK-8 法测定神经胶质瘤细胞系的增殖。采用 Transwell 小室实验评估神经胶质瘤细胞系的侵袭和迁移。
研究结果表明,HAND2-AS1 在神经胶质瘤组织和细胞系中表达显著下调。此外,过表达 HAND2-AS1 可减弱神经胶质瘤细胞系的增殖、侵袭和迁移。然而,过表达 CDK6 可部分阻断 HAND2-AS1 对神经胶质瘤细胞系中细胞增殖以及细胞侵袭和迁移的抑制作用。
长链非编码 RNA HAND2-AS1 通过负调控 CDK6 的表达,在神经胶质瘤中发挥着重要的抑瘤作用。
