Abstract

Abstract: Liver fibrosis and cirrhosis are primarily caused by the activation of hepatic stellate cells (HSCs), regardless of their etiology. Collagen type I (collagen I) and connective tissue growth factor (CTGF) is produced more readily by activated HSCs. Consequently, identifying the molecular and cellular mechanisms responsible for HSCs activation is essential to better understand its mechanism of action and therapeutic potential. Cell death is caused by iron‐dependent lipid peroxidation during ferroptosis. Ferroptosis plays an important role in the survival of activated HSCs and could contribute to the development of innovative prevention and treatment strategies for liver fibrosis. Danshensu (Dan) is a pure molecule extracted from the Salvia miltiorrhiza herb that protects against liver damage. However, Dan's effect on attenuating HSCs activation by regulating ferroptosis remains unclear. The results of this study indicated that lipopolysaccharide (LPS)‐induced LX‐2 and T6 cells activation occurs through the upregulation of collagen I, CTGF, Gpx4, and SLC7A11. Interestingly, Dan attenuated LPS‐induced liver fibrosis in those cells by upregulating collagen I, CTGF, Gpx4, and SLC7A11 and by increasing lipid reactive oxygen species accumulation. Furthermore, the results also showed that the ferroptosis inhibitor liproxstatin attenuated the overproduction of lipid reactive oxygen species in LPS‐activated LX‐2 cells. We conclude that Dan attenuates LPS‐induced HSC activation during liver fibrosis by regulating ferroptosis in LX‐2 and T6 cells. Abstract : Danshensu (Dan) attenuates lipopolysaccharide‐induced hepatic stellate cells activation via decreasing expression of collagen І, connective tissue growth factor, glutathione peroxidase 4, cystine/glutamate antiporter xCT, and lipocalin‐2. However, Dan increases lipid reactive oxygen species accumulation.
