dc.description.abstractIn order to identify a fibrogenic factor associated with the potential of hepatic stellate cells (HSC) activation that arises during the CCl4-induced fibrogenic process, the relationship between the activation of HSC and levels of several fibrogenic factors were investigated. After isolation of HSC from the liver at different stages of CCl4 intoxication, the activation of HSC was assessed by the expression of α-smooth muscle actin. Levels of cytokines and oxidative stress in liver homogenates and plasma were measured by enzyme linked immunosorbent assay and the colorimetric method. In primary culture, HSC isolated from a rat liver were gradually activated in a time-dependent manner according to CCl4 administration. The progression of HSC activation was closely correlated with parameters related to oxidative stress in liver homogenates rather than the tissue levels of several cytokines. Also, the levels of antioxidants and arginase activity were inversely correlated with HSC activation. In plasma, the levels of oxidative stress and cytokines in CCl4-treated rat livers were not associated with the activation of HSC found during the CCl4-induced fibrogenic process. The relationship between HSC activation and oxidative stress was also confirmed through several factor-treated HSC cultures. In conclusion, the activation of HSC was accelerated according to CCl4 administration, and the progression of HSC activation is absolutely related to the oxidative stress. These results show that enhanced oxidative stress is an important signal for activation of HSC in experimental liver fibrogenesis.-
