FGF-2 stimulates rRNA transcription in vitro. (a) The amount of rRNA transcription in the presence of the indicated combinations of purified proteins was measured using S1 nuclease protection. (b) Band intensities in panel a were quantified and normalized to the amount of rRNA transcription in the presence of RNA Pol I and SL1 (lane 1). Bars represent the standard errors of four determinations. Relative to lane 1, P values of lanes 2 to 8 were 0.07, 0.0009, 0.05, 0.0004, 0.005, 0.09, and 0.2, respectively.
