Fig. (2) miR-9 and SMC1A expression levels in lentivirus infected U87 and U251 cells.(A) miR-9 level was significantly increased after the lentivirus vector infection in both cell lines. SMC1A level was significantly decreased by either miR-9 overexpression or the gene knockdown with RNAi of SMC1A (SMC1A KD, KD for knock down). The result is average of three independent replicates. **indicates significance at p<0.01. ***indicates p<0.005; (B) Western blot analysis of SMC1A protein levels either in miR-9 overexpression or in the gene knockdown with RNAi of SMC1A.
