Abstract
Background: Liver fibrosis disease is often attributed to the activation of Hepatic Stellate Cells (HSC) and excessive scarring in the liver. Isoramantin has a protective effect against liver fibrosis by inhibiting the expression of fibrogenic genes caused by Transforming growth factor beta (TGF-β1). In this research, the role of Isorhamnetin in inhibiting the activation of liver stellate cells has been investigated.
Methods: First, the cells were cultured in DMEM culture medium with 10% of Fetal Bovine Serum (FBS) until reaching the appropriate density, and were treated with 75, 100 μM of Isorhamnetin for 24 hours, then the expression levels of NADPH Oxidase (NOX1, NOX2), Collagen1α, alpha-smooth muscle actin (α-SMA) and Reactive oxygen species (ROS) levels were measured to evaluate liver fibrosis.
Findings: The results showed that the expression level of NOX1, NOX2, Collagen1α, and α-SMA genes and the level of ROS in the concentration of 2ng/m of TGF-β increased significantly compared to the control group. Also, in the presence of 75 and 100 μM Isorhamnetin, the expression of these genes and the level of ROS decreased significantly compared to the fibrosis group.
Conclusion: TGF-β increases the expression of genes involved in the progression of liver fibrosis and increases the level of ROS, which increases the production of extracellular matrix, including collagen 1α. Isorhamnetin reduces the expression of genes involved in the development of liver fibrosis. Thus, it can prevent the development of liver fibrosis.
