FN1 and Hepatic fibrosis: RNA (Figure 5A,B) and protein‐based (Figure 5C,D and Figure S15A,B) analyses confirmed that CKI resulted in diminished expression of liver fibrosis‐related genes TGF‐β1, COL1A, Fibronectin, and TIMP1 in a dose‐dependent manner, which were upregulated in TGF‐β1‐treated LX‐2 cells.
