| Popis: | Long non-coding RNAs (lncRNAs) have been widely highlighted due to their involvement in various types of cancers, including glioma; however, the exact mechanism and function by which they operate in regard to spinal cord glioma remain poorly understood. LOC101928963 was screened out for its differential expression in spinal cord glioma by microarray analysis. Therefore, this study was conducted to investigate the modulatory effects of LOC101928963 on spinal cord glioma by binding to phorbol-12-myristate-13-acetate-induced protein 1 (PMAIP1). The expression of LOC101928963 and LOC101928963 was characterized in spinal cord glioma tissues, and their interaction was examined by dual-luciferase reporter gene assay. Cells with LOC101928963 that exhibited elevated or suppressed levels of PMAIP1 were established to substantiate the mechanism between LOC101928963 and PMAIP1. qRT-PCR and western blot methods were subsequently applied to determine the expression of cell-proliferation- and apoptosis-related genes in response to the alterations of LOC101928963 and PMAIP1. Glioma cell proliferation and apoptosis were assessed by MTT assay and flow cytometry. Decreased cell apoptosis and PMAIP1 expression, as well as overexpressed LOC101928963, were exhibited among spinal cord glioma tissues. LOC101928963 overexpression was observed to promote cell proliferation and cell-cycle entry and inhibit the process of apoptosis. PMAIP1, a target of LOC101928963, displayed a downregulated level following the elevation of LOC101928963. The present results strongly emphasize the neutralization effect of PMAIP1 overexpression on spinal cord glioma progression induced by the overexpression of LOC101928963. The data obtained during the study highlighted the inhibitory role of LOC101928963 silencing in spinal cord glioma through the increase in PMAIP1, which suggests a potential target in the treatment of spinal cord glioma.
