Objectives : The effects of cotreatment of adriamycin and ethanol extract of herb (Palgin-tang hab Hwajuck-hwan a traditional medicine for cancer treatment in oriental medicine) on the induction of apoptotic cell death were investigated in human liver origin cell lines, Chang.
Methods : Chang(ATCC) liver cells were cultured in RPMI-1640(Gibco SRL Co, Gaithersburg, MD) badge including 10% fetal bovine serum. Chang liver cells were treated with various concentrations(from 10 to ) of adriamycin and herb extract(from 500 to ) After 48h later, the cells were tested for viability by Crystal violet staining assay. Adriamycin and Herb extract induced ladder pattern of DNA fragmentation in Chang cells. Genomic DNA was isolated and separated on 1.5% agarose gels. The DNA was stained with ethidium bromide and visualized under UV light.
Results : The death of Chang cells was synergistically induced by the cotreatment of adriamycin and ethanol extract of herb. In addition, the cotreatment-induced cell death of Chang cells was mediated by apoptotic death signal processes. The phosphotransferase activity of JNK1 remained in a basal level in Chang cells which was treated individually with the adriamycin and ethanol extract of herb. However, it was markedly increased in Chang cells which was cotreated with adriamycin and ethanol extract of herb. In addition, the expression of Fas and FasL was markedly induced by the cotreatment of adriamycin and herb extract. For a while, the expression of Sax was a eminently increased by the ethanol extract of herb. However, Scl2 expression was not affected by the individual or cotreatment of adriamycin and herb extract.
Conclusions : our results suggest that the cotreatment of adriamycin aM ethanol extract of herb induces synergistic apoptotis of human liver origin Chang cells via the upregulation of JNK, Fas, FasL and Bax.
