The endothelial-to-mesenchymal transition (EndMT) has been demonstrated to be
involved in pulmonary vascular remodeling. It is partly attributed to oxidative
and inflammatory stresses in endothelial cells. In current study, we conducted a
series of experiments to clarify the effect of salvianolic acid A (SAA), a kind
of polyphenol compound, in the process of EndMT in human pulmonary arterial
endothelial cells and in vivo therapeutic efficacy on vascular remodeling in
monocrotaline (MCT)-induced EndMT. EndMT was induced by TGF?1 in human pulmonary
arterial endothelial cells (HPAECs). SAA significantly attenuated EndMT,
simultaneously inhibited cell migration and reactive oxygen species (ROS)
formation. In MCT-induced pulmonary arterial hypertension (PAH) model, SAA
improved vascular function, decreased TGF?1 level and inhibited inflammation.
Mechanistically, SAA stimulated Nrf2 translocation and subsequent heme
oxygenase-1 (HO-1) up-regulation. The effect of SAA on EndMT in vitro was
abolished by ZnPP, a HO-1 inhibitor. In conclusion, this study indicates a
deleterious impact of oxidative stress on EndMT. Polyphenol antioxidant treatment
may provide an adjunctive action to alleviate pulmonary vascular remodeling via
inhibiting EndMT.
