Figure 3 depicts the expression of each gene comprising the most accurate gene signature in F1/2 and F3/4 fibrosis. Chitotriosidase (CHIT1) expression (Figure 3A) was increased in F3/4 fibrosis and that of FCER1G, OSM, VEGFA, and ZAP70 (Figure 3B–E) was decreased. Supplementary Figure S1 describes the expression of each gene comprising the gene signature in each stage of liver fibrosis. The gene discussed is OSM; the disease is Hepatic fibrosis.
