Knockdown of p400 and SRCAP expression differently regulates transcription of the Sp1 promoter and p21 promoter. A549 cells were transfected where indicated with control, SRCAP or p400 siRNA, harvested 72 hours later and total RNA isolated. In (a), the level of Sp1 mRNA was assessed using RT-qPCR using primers listed in [3]. In (b), the level of p21 mRNA was determined by RT-qPCR using primers listed in Table  S1(a). The graphs show the mean result and standard error from three experiments.
