Expression of protein and mRNA of fibroblast activation protein (FAP) in transplanted lung tissue for patients with and without idiopathic pulmonary fibrosis (IPF). (A and B) The frozen lung tissues from healthy donors (n = 6) and patients with IPF (n = 8) or non-IPF interstitial lung disease (silicosis, n = 12) were used for FAP expression evaluation by Western blot. **P < 0.01. (C) Real-time PCR analysis of FAP mRNA expression. β-actin was used as an internal reference gene to normalize the expression of FAP. The relative expression of FAP in one healthy donor (1#) was designated as sample control and set at one. The expression folds in other individuals were calculated through comparison to control subjects. The dashed line is a median. **P < 0.01 and ***P < 0.001.
