LncRNA MALAT1 Inhibits Apoptosis and Promotes Invasion by Antagonizing miR-125b in Bladder Cancer Cells
Experimental verification
qPCR,Western blot etc.
Functional description
MALAT1 is capable of suppressing mature miR-125b and increasing the expression of its target genes (Bcl-2 and MMP-13), but has no effect on pri-miR-125b and pre-miR-125b.We observe that the biotin-labeled MALAT1–RNA probe is able to pull down Ago2 and miR-125b and that the negative regulation of miR-125b by MALAT1 is dependent on Ago2. Importantly, the results of flow cytometry assay and transwell assay reveal that the MALAT1-mediated cancer progression is in part due to specific suppression of miR-125b and activation of its two target genes. All together, these data suggest that the “MALAT1-miR-125b-Bcl-2 / MMP-13� axis plays an important role in the progression of BCa, thereby may provide a potential therapeutic strategy for the treatment of human BCa.
