The overexpression of miR-146b-5p in glioblastoma cell lines led to MMP16 mRNA silencing, MMP2 inactivation, and the inhibition of tumour cell migration and invasion.
We showed that miR-146b overexpression by transfection with the precursor miR-146b, or knock-down by Locked Nucleic Acid (LNA)-modified anti-miR-146b, has no effect on the growth of human glioblastoma U373 cells.
