Figure 3 NORAD silencing reduced the expression of migration-related genes in glioma cells. The MMP2, MMP9, and vimentin (A) protein and (B) mRNA expression was detected using western blotting and RT-qPCR, respectively. All experiments were repeated 3 times independently (n=3). ** P<0.01, *** P<0.001 versus si-NC. NORAD – noncoding RNA activated by DNA damage; mRNA – messenger RNA; RT-qPCR – reverse transcription-quantitative polymerase chain reaction; si-NC – negative control for NORAD siRNA.
