Knockdown of long noncoding RNA AB073614 inhibits glioma cell proliferation and migration via affecting epithelial-mesenchymal transition

OBJECTIVE: This study was aimed to explore the role of long noncoding RNA (lncRNA) AB073614 and its potential mechanisms in the glioma development.

MATERIALS AND METHODS: Expression levels of lncRNA AB073614 in glioma tissues and glioma cell lines were evaluated by quantitative real-time PCR (qRT-PCR). MTT assays were conducted to explore the impact of AB073614 down-regulation on the proliferation of human glioma cells. The effects of AB073614 knockdown on cell proliferation and migration were evaluated by in vitro assays. EMT-related molecular markers expression level was detected by qRT-PCR assay and Western blot analysis.

RESULTS: We confirmed that AB073614 was significantly upregulated in glioma tissues and cell lines (p < 0.01). In vitro studies demonstrated that knockdown of AB073614 inhibits U251 cell proliferation and migration. Moreover, knockdown of AB073614 could inhibit epithelial-mesenchymal transition (EMT) phenotype in glioma cells.

CONCLUSIONS: AB073614 functions as a tumor promoter in glioma. This finding may provide a therapeutic approach for future treatment of glioma.
