Fig. 2. BRG1 rescues CIITA induction in SW13 cells. SW13 cells were left uninfected (lanes 1 and 2), or infected with AdtTa virus alone (lanes 3 and 4) or together with AdBRG1 (lanes 5–8) or AdK798R (lanes 9–12) in the absence (lanes 1–6) or presence of tetracyline (lanes 7–12). After 20 h, cells were exposed to no cytokine (lanes 1, 3, 5, 7, 9 and 11) or IFN-γ (lanes 2, 4, 6, 8, 10 and 12) for an additional 6, 12 or 24 h. RT–PCR was used to measure CIITA, GBP-1 or β-actin RNA levels. The experiment was performed three times. Representative samples are shown.
