The effect of the concentration of DFO or 311 on mRNA levels of the TfR, N-myc, WAF1, β-actin, mdm-2, and GADD-45 in BE-2 neuroblastoma cells. (I-A) Ethidium bromide staining of the agarose gel; (I-B) TfR; (I-C) N-myc; (I-D) WAF1; (I-E) β-actin. (II-A) Ethidium bromide staining of the agarose gel; (II-B) mdm-2; (II-C) GADD45; (II-D) β-actin. The result shown is a typical experiment from three experiments performed.
