SNAI1 and bronchopulmonary dysplasia: \In contrast, again similar to BPD development, IAI-exposed pups receiving the eNAMPT-neutralizing mAb prenatally, showed attenuation of each index of PH including reduced arterial wall thickness (Figure 4A), preserved CD31 expression (Figure 4B), reduced expression of PH markers, SNAIL1 and STAT3 (Figures 4C,D), and reduced RVSP and Fulton index measurements (Figures 4E,F).
