The effects of eolehicine on HSCs growth were measured by MTT assay. Effects of eolchicine on gene expression of HSCs were analysed by using a self-made oligonucleotide mieroarray. Colehieine inhibited HSCs growth in a dose-dependent manner. After 12 h of treatment with 6.25 mg/L of colehicine, the expression of tissue inhibitor of metalloprotenase-1 （TIMP-1） and the expression of interleukin-6 （IL-6） in HSCs were downregulated by 2.3 folds and 2.1 folds, respectively. These results suggest that colchieine＇s beneficial effects may, at least in part, owe to the inhibitory to the proliferation of HSCs and down regulation of the expression of both TIMP1 and IL-6 in HSCs.展开更多
