PDGFRB and Hepatic fibrosis: Our findings revealed that the expressions of p-PDGFR-β/PDGFR-β proteins were significantly higher than those in the normal control group after CCl4 treatment, whereas administration of 40 g/kg Eup significantly downregulated the ratio of p-PDGFR-β/PDGFR-β proteins in the liver fibrosis model (Figure 6B,C).
