Finally, the PPI network from the IPF group without PJ was integrated by 50 nodes and 117 edges (Figure S3), and we detected 4 protein communities (Figure 2F), which we named JAK-STAT signaling/interleukin 12, scavenger receptors/vesicle-mediated transport, humoral immune response, and amyloid fiber formation/senescence complexes. The gene discussed is SOAT1; the disease is idiopathic pulmonary fibrosis.
