4种中药制剂对人肺癌A549细胞增殖的影响

目的　研究人肺癌A5 49细胞和乳腺癌MCF7细胞对市售 4种中药制剂 (斑蟊酸钠、苦参素、华蟾素和川芎素 )的敏感性 ,以及川芎素影响肺癌A5 49细胞增殖的可能机制。方法　采用MTT法测定药物对细胞增殖的抑制率和药物间的协同抑制作用 ;流式细胞法测定细胞周期。结果　4种中药对乳腺癌MCF7细胞的增殖均有不同程度的抑制作用 ,但只有川芎素可明显抑制肺癌A5 49细胞的增殖 ;川芎素与 3种化疗药物联合对A5 49细胞有协同作用 ;川芎素可诱导A5 49细胞凋亡。结论　斑蟊酸钠、苦参素和华蟾素对不同肿瘤细胞的抑制效果差异很大 ;川芎素不仅有抑制肿瘤细胞增殖的作用 ,还与化疗药物有协同效果 ;川芎素抑制A5 49细胞增殖的机制与其诱导细胞凋亡有关。

ffects of four extracts of traditional Chinese medicinal materials on the proliferation of human lung cancer A549 cell line

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.
