Abstract

BACKGROUND: Iron overload is a prominent characteristic of liver injury, but there is no effective treatment at present. Qizhufang (ZSF) is a Chinese herbal formula showed anti-HBV activities, improved liver function, and anti-fibrosis effect. ZSF showed a series of liver-protection functions, but whether ZSF can relieve hepatic iron overload is still unclear.

MATERIAL AND METHODS: Ferric ammonium citrate (FAC) was used to construct iron-overloaded LO2 cells. The cell apoptosis and proliferation were measured by flow cytometry and CCK-8 assay, respectively. ROS level was analyzed by fluorescence probe. RNA and protein expressions were assessed by real-time PCR and Western blot.

RESULTS: FAC upregulated apoptosis rate, ROS level, and expression of hepcidin and p-STAT3, but suppressed proliferation and expression of DMT1, FPN1, and CP in LO2 cells. However, Qizhufang (ZSF) reversed the effect of FAC. We also found that hepcidin overexpression suppressed the expressions of DMT1, FPN1, and CP, which were reversed by ZSF. Additionally, STAT3 inhibitor AG490 suppressed hepcidin expression. Moreover, exogenous IL-6 reversed the effect of ZSF on apoptosis rate, ROS level, and the expression of hepcidin, DMT1, FNP1, CP, and p-STAT3.

CONCLUSIONS: Qizhufang (ZSF) can ameliorate iron overload-induced injury by suppressing hepcidin via the STAT3 pathway in LO2 cells.
