Phosphorylated and total Smad3 are overexpressed in IPF-HLFs. Protein interaction networks were constructed using STRING ( a. Proteins and RNA were extracted from human lung fibroblasts from patients with IPF (IPF-HLF) or control donors (N-HLF). phospho and total Smad3 protein levels were tested using Western Blot b-c. Smad3 d and soluble IL-6R e mRNA levels were measured by qPCR. *p < 0.05, **p < 0.01, and ***p < 0.001 (n ≥ 4)
