Figure 3

(A) Pulmonary artery (size 72–96 µm) histology in C (controls), Cavtr+ (M + H+ cavtratin) and Cavtr– (M + H). The artery in the control is thin walled. In the M + H group the arteries appear thickened. In the cavtratin-treated group, the arteries appear less thickened. (B) Immunofluorescence study: Caveolin-1 (green) and smooth muscle α-actin (red) in pulmonary arteries (size 27–143 µm). There is significant loss of endothelial caveolin-1 in MCT + hypoxia group, and cavtratin-treated rats show recovery of endothelial caveolin-1.
