ANG II does not cause cell death or activate activator protein-1 (AP-1) in the SFO. A: representative terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining (green) in SFO sections from untreated (day 0) and ANG II-infused mice (day 14). A positive control section from the intestine is shown on the right. DAPI staining is shown in blue; n = 3. Scale bar = 100 μm. B: summary of temporal changes in SFO AP-1-dependent photon emission during ANG II infusion; n = 6–8/group.
