C/EBPα 30-kDa and BRM2 mutant proteins do not down-regulate c-Myc. (A) The figure shows the same set of Northern blots from Figure 3A hybridized to c-Myc and GAPDH probes. The hybridization signal was quantitated on a Phosphorimager and the data presented in Table 2. (B) The same set of Northern blots from Figure 3B hybridized to c-Myc and GAPDH probes. The blots for the 42-kDa C/EBPα-ER fusion in panel A and B are 2 completely independent experiments from 2 different inductions of transfected K562 cells.
