Tóm tắt

Our aim was to clarify the regulations of lncRNA HOXA11-AS (HOXA11-AS) played on the progression of glioma as well as to investigate the mechanisms by which HOXA11-AS modulated development of glioma. This study confirmed the regulations of miR-124 and HOXA11-AS on the progression of glioma. Here, HOXA11-AS was overexpressed and miR-124 was underexpressed in glioma. Expression of miR-124 was negatively related to that of HOXA11-AS. Silencing of HOXA11-AS suppressed cell proliferation, invasion, and promoted apoptosis in glioma cells in vitro. Moreover, inhibition of HOXA11-AS expression repressed glioma xenograft tumor growth. Expression of miR-124 was repressed by HOXA11-AS functioning as sponge. In addition, miR-124 knockdown partially abolished the inhibitory roles of HOXA11-AS downregulation in glioma cells. Conclusively, this study suggested that silencing of HOXA11-AS restrained proliferation, invasion, induced apoptosis of glioma cells, and repressed xenograft growth via modulating miR-124 expression and thus inhibited glioma progression.
