OBJECTIVE: Long non-coding RNA LINC00961 (LINC00961) has been reported to play an important role in tumor development and metastasis of lung cancer. However, the expression and role of LINC00961 in glioma remains unclear. The present study aimed to investigate the expression of LINC00961 in patients with glioma and to investigate its effect on glioma cells.

PATIENTS AND METHODS: Quantitative Real-Time PCR (qRT-PCR) was performed to detect the expression of LINC00961 in glioma tissues and cell lines. Then, the association between LINC00961 expression and clinical pathological parameters and prognosis of glioma patients were further evaluated. Gain of function studies were performed to determine the effects of LINC00961 on proliferation and metastasis of glioma cells. Western blotting assay was used to explore the regulation mechanism.

RESULTS: We found that LINC00961 was significantly downregulated in glioma tissues and cell lines compared with that of adjacent normal brain tissues and normal human astrocytes. Low expression of LINC00961 was significantly correlated with WHO grade and KPS score. Clinical analysis indicated that patients with low LINC00961 expression had a shorter overall survival than those with high expression. Univariate and multivariable Cox regression analyses further identified that down-regulated LINC00961 might act as an independent prognostic factor for glioma patients. Functionally, overexpression of LINC00961 significantly suppressed glioma cells proliferation, migration, and invasion. Mechanistically, we found that overexpression of LINC00961 inhibited glioma cell EMT.

CONCLUSIONS: LINC00961 might be considered as a novel molecule involved in glioma development, which provides an independent prognostic indicator and a potential therapeutic target for glioma patients.
