Effect of PDGFR-β-specific short hairpin RNA on the variability of C6 glioma cells. The viability of the CON, NC and KD cells was determined using MTT assays. The viability of the KD cells was decreased compared with the CON and NC cells from 12–72 h. *P<0.05 vs the CON cells. Data were obtained from three independent experiments and are shown as the mean ± standard deviation. CON, control C6 cells; NC, negative control C6 cells; KD, PDGFR-β-knockdown C6 cells; PDGFR-β, platelet-derived growth factor receptor-β.
