To further determine the linking factors between A‐FABP and liver fibrosis, the hepatic expression of fibrogenic cytokines was examined.[6, 27] BDL‐induced mRNA levels of TGFβ1 (encoded byTgfb1), connective tissue growth factor (CTGF, encoded by Cnn2), and TIMP‐1 (encoded by Timp1) were significantly attenuated in A‐FABP KO mice, while that of platelet‐derived growth factor subunit B (PDGFB, encoded by Pdgfb) was not altered when compared to those in WT mice (Figure 4A). This evidence concerns the gene PDGFB and Hepatic fibrosis.
