A. hMSC (left panel) and HNP( right panel) cells were transfected with pG5-EWS-FLI-1 or a control plasmid. REST and EWS-FLI-1 expression levels were determined by RT-PCR. GAPDH was used as the internal control.
B. hMSC were transfected with pG5-EWS-FLI-1 or a control plasmid. REST protein expression was detected by Western blot. β-Actin was used as the internal control.
C. TC71 and A4573 human Ewing sarcoma cells were transfected with siEWS-FLI-1 or siControl vector. EWS and REST protein levels were determined by Western blot. β-Actin was used as the internal control.
D. TC71 cells were transfected with siREST or the siControl vector. EWS-FLI-1 and REST levels were determined by RT-PCR. The 18S primer was used as the internal control.
