Effects of four extracts of traditional Chinese medicinal materials on the proliferation of human lung cancer A549 cell line / 中国药理学通报

ABSTRACT

AIM: To study the influence of four extracts of traditional Chinese medicinal materials sodium cantharidinate, matrine, cinobufotain and sodium ferlate) on the proliferation of human lung cancer A549 cell line and breast cancer MCF7 cell line;the possible mechanism of sodium ferlate on the inhibition of A549 cells. METHODS: The inhibition of cell proliferation was determined by MTT assay and cell cycle was determined by flow cytometry. RESULTS: All four extracts of traditional Chinese medicinal materials showed growth inhibition to breast cancer MCF7 cells while only sodium ferlate showed inhibition to lung cancer A549 cells. Synergistic inhibition was found when sodium ferlate was combined with each of the three commonly-used chemotheraputic drugs. Sodium ferlate could induce A549 cell apoptosis. CONCULSION The inhibition of cell proliferation induced is by sodium cantharidinate, matrine, and cinobufotain is quite different between different cancer cell lines. Sodium ferlate can inhibit cancer cell proliferation and show synergistic action while combined with chemotheraputic drugs. The mechanism of sodium ferlate on A549 cell proliferation seem to be related to the cell apoptosis.
