TGFB1 and pulmonary fibrosis: First, we examined canonical myofibroblast markers (Hinz and Lagares, 2020), collagen produced by myofibroblasts (Zhang et al., 1994), genes upregulated in myofibroblasts derived from idiopathic pulmonary fibrosis (IPF) patients (Strunz et al., 2020), and effectors and targets of TGF-β signaling in two data modalities: bulk RNA-seq and bulk proteomics (Figure 8A).
