LncRNA MAFG-AS1 facilitates the migration and invasion of NSCLC cell via sponging miR-339-5p from MMP15.

Abstract:

:Non-small-cell carcinoma (NSCLC) is the most common cancer along with high mortality rate worldwide. In the present study, our data showed that lncRNA MAF BZIP Transcription Factor G Antisense RNA 1 (MAFG-AS1) was over-expressed in NSCLC tissues and cell lines. Overexpression of MAFG-AS1 promoted the migration, invasion and enhanced epithelial-mesenchymal transition (EMT) of NSCLC cell. In addition, miR-339-5p was predicted to be a target of MAFG-AS1 and the level of miR-339-5p was down-regulated in NSCLC. Over-expression of MAFG-AS1 significantly decreased the level of miR-339-5p in NSCLC cell. Moreover, the matrix metalloproteinase 15 (MMP15) was identified to be a target of miR-339-5p. The level of MMP15 was negatively regulated by miR-339-5p whereas positively controlled by MAFG-AS1. In addition, up-regulation of miR-339-5p neutralized the promoting impact of MAFG-AS1 on the migration, invasion and EMT of NSCLC cell. Finally, the xenograft model suggested that MAFG-AS1 promoted the metastasis of NSCLC cell in vivo. Altogether, we proved that MAFG-AS1-miR-339-5p-MMP15 axis might be a promising therapeutic target for the treatment of patients with NSCLC.
