Figure 2From: USF2 inhibits C/EBP-mediated transcriptional regulation of the RIIβ subunit of cAMP-dependent protein kinaseA novel USF1 isoform is induced by cAMP. Immunoblotting was performed with antibodies specific for the C-terminal regions of USF1 (Panel A) or USF2 (Panel B) on stimulated (+, 100 μM 8-CPT-cAMP, 28 h) or unstimulated (-) nuclear extracts. 20 μg of nuclear exracts was loaded in each lane, and equal loading was determined by coomassie staining.Back to article page
