“…Accordingly, oligonucleotides corresponding to rat rDNA core promoter or USF inhibited both pol I and pol II transcription. The pol I promoter, therefore, belongs to a family of other E-box containing USF-activated cellular promoters that include those of alcohol dehydrogenase (Potter et al, 1991), mouse metallothionein-I (Carthew et al, 1987;Mueller et al, 1988), human heme oxygenase (Sato et al, 1990), human insulin (Read et al, 1993) and human CD2 (Outram and Owen, 1994). In addition to activation of alcohol dehydrogenase, human insulin and CD2 genes, USF is also known to stimulate pol III transcription of U6 small nuclear RNA gene (Li et al, 1994).…”
