Effects of bioencapsulated CTB-ACE2 and CTB-Ang-(1–7) on
(A) Fulton index (a marker of RV hypertrophy; calculated as the
ratio of the right ventricle [RV] weight to the weight of the left ventricle
plus septum [LV+S], (B) RV systolic pressure (RVSP),
(C) cardiac index (CI; determined echocardiographically),
(D) total pulmonary resistance index (TPRI [a marker of RV
afterload]; calculated as ratio of RVSP and CI), and (E) pulmonary
vascular remodeling (quantified as percent wall area). Representative
photomicrographs of peripheral pulmonary arteries (Verhoeff-van Giesson stain)
are shown on the bottom of (E); quantification of percent wall area
is shown on right. CTB-ACE2, CTB-Ang-(1–7) or PBS were administered as
outlined in Figure 4. Each data point
represents one animal. Values are means ± SEM. #p <0.05 vs.
control, *p <0.05 vs. sham by one-way ANOVA and post-hoc Newman-Keuls
test. Ctrl = untreated control; MCT = monocrotaline.
