A summary of the article is shown below:

OBJECTIVE: To investigate the inhibitory effects of silencing migration-inducing gene-7 (Mig-7) on vasculogenic mimicry formation, migration and invasion of human glioma cells in vitro and whether MEK/ERK signaling pathway mediates these effects.METHODS: Human glioma U251 cells were infected by lentiviral vectors carrying a small interfering RNA targeting Mig-7 gene (sh-Mig-7) or a negative control shRNA (sh-NC), and real-time quantitative PCR was used to detect the expression level of Mig-7 mRNA in the cells. Three-dimensional culture and Transwell chamber invasion assay were used to observe the effect of Mig-7 gene silencing on vasculogenic mimicry formation and invasion ability of the U251 cells. Western blotting was performed to detect the changes in the protein expression levels of MEK/ERK in the infected cells.RESULTS: We successfully obtained a U251 cell line with stable low expression of Mig-7 gene using RNA interference technique. Compared with the cells infected with sh-NC lentivirus and the non- infected cells, U251 cells infected with the lentiviral vector carrying sh-Mig-7 showed significantly decreased expression level of Mig-7 (P < 0.01) with obviously lowered vasculogenic mimicry formation and invasion abilities (P < 0.05). Mig-7 silencing also significantly lowered the expressions of MEK and ERK proteins in U251 cells (P < 0.05).CONCLUSIONS: Silencing of Mig-7 gene inhibits vasculogenic mimicry formation and invasion of U251 cells possibly by suppressing MEK/ERK signaling, suggesting the important role of Mig-7 gene in vasculogenic mimicry formation and invasion of human glioma cells.
