KLF14 and Hepatic fibrosis: Next, we investigated whether KLF14 regulated hepatic fibrogenesis in vivo, we ectopically enforced the KLF14 expression in a TAA‐induced rat liver fibrosis model by injecting KLF14‐expressing adenovirus via tail vein, with or without PPARγ inhibition by intraperitoneal GW9662 administration (Figure 7A).
