Immunohistochemical staining of the lung tissues for candidate proteins in each group. A0–A2: caveolin-1 expression in the lung tissue of each group, B0–B2: FLNA expression in the lung tissue of each group, C0–C2: cathepsin D expression in the lung tissue of each group, D0–D2: GSTM1 expression in the lung tissue of each group. 0, 1, 2 represent the normal, reversible CHD-PAH, and irreversible CHD-PAH groups, respectively. Caveolin-1, FLNA, and cathepsin D were significantly upregulated and GSTM1 was downregulated expression in the irreversible CHD-PAH group, compared to the reversible and control groups. These tendencies were also significant between the reversible CHD-PAH group and control group.
