Abstract:
OBJECTIVE： To investigate the effects of chelidonine on proliferation， collagen synthesis and TGF-β1 receptor of activated hepatic stellate cells CFSC-8B. METHODS： CFSC-8B cells in logarithmic phase were collected and then divided into normal control group， model group， solvent group （ethanol）， positive control group （1 μg/mL colchicine ethanol solution）， chelidonine low， medium and high concentration groups （2.1， 4.2， 8.4 μg/mL chelidonine ethanol solution）. Except for normal control group， other groups were activated with 20 μg/L TGF-β1 for 24 h； the latter 5 groups were intervened with relevant medicine for 24 h. Cell proliferation of activated cells was assayed by CCK-8 assay. Hydroxyprolin （Hyp） content was assayed by enzyme digestion； the levels of typeⅠ collagen （Col-Ⅰ） and type Ⅲ collagen （Col-Ⅲ） were assayed by ELISA； the expressions of TβR-Ⅰ and TβR-Ⅱ protein were assessed by Western blot； mRNA expressions of α-SMA， TβR-Ⅰ and TβR-Ⅱ in hepatic stellate cells were assessed by RT-PCR. RESULTS： Compared with normal control group， cell proliferation rate， Hyp content， the levels of Col-Ⅰ and Col-Ⅲ， the protein expressions of TβR-Ⅰ and TβR-Ⅱ as well as mRNA expressions of α-SMA， TβR-Ⅰ and TβR-Ⅱ were increased significantly （P＜0.05）. Compared with model group， there were no significant difference in above indexes of hepatic stellate cells in solvent group （P＞0.05）； there were no significant difference in the proliferation rate of hepatic stellate cells in chelidonine low concentration group （P＞0.05）， above indexes of hepatic stellate cells were decreased significantly in positive control group and chelidonine high concentration group （P＜0.05）. The decrease of Hyp and Col-Ⅲ levels were not significant in chelidonine medium concentration， but other above indexes were decreased significantly （P＜0.05）. Compared with chelidonine medium concentration group， the rate of cell proliferation， Col-Ⅰ level， protein and mRNA expressions of TβR-Ⅰ and TβR-Ⅱ were decreased significantly in chelidonine high concentration group （P＜0.05）. CONCLUSIONS： Chelido- nine can inhibit the proliferation， collagen synthesis as well as the protein and mRNA expressions of TβR-Ⅰand TβR-Ⅱ in activated CFSC-8B cells.
