Abstract

Now, numerous exciting findings have been found that long noncoding RNAs (lncRNAs) play a vital role in cancer malignant progression. However, their potential involvement in glioma is not well understood. Here, we performed a high-throughput microarray to detect the lncRNA expression profiles between glioma cell lines and normal astrocyte cell lines. HOXD-AS2 was increased in glioma cells and it was associated with glioma grade and poor prognosis. Loss of HOXD-AS2 can inhibit glioma cell growth by inducing cell-cycle G1 arrest in vitro. The proliferation of glioma was inhibited followed by knocking down the expression of HOXD-AS2 not only in subcutaneous injection model but also in orthotopic implantation model. These findings indicate that HOXD-AS2 promotes the glioma progression and may serve as a potential target for glioma diagnosis and therapy.
