Optimization of effective component formula from active ingredients of Salvia Miltiorrhiza and Panax Ginseng through orthogonal design method to resist breast cancer / 中国药理学通报

Aim To optimize the most effective compo-nent formula from the active ingredients of Salvia Milti-orrhiza and Panax Ginseng through the orthogonal de-sign method to resist breast cancer, and to reveal its antitumor mechanism in MCF-7 cells. Methods The human breast cancer cells MCF-7 were employed as the research object and the normal breast epithelial cells MCF-10A were used as control,optimizing the most ef-fective component formula from the active ingredients of Salvia Miltiorrhiza and Panax Ginseng by using CCK-8 assay and orthogonal design method; real-time cell a-nalysis was used to monitor the best combination formu-la on cell proliferation, and high content screening was used to detect the best combination drug on cell apop-tosis. Results The best combination of the salvianolic acids, saponins of Panax Ginseng and ginseng polysac-charides that were screened out were 5 , 10 , 5 mg · L-1 . Compared with control group, the treatment group had effective response inhibiting the proliferation on MCF-7 cells, but those effects were weaker on MCF-10A cells through real-time cell analysis. Ho-echst, Annexin V, PI staining fluorescence showed no significant difference ( P >0. 05 ) on MCF-10 A cells compared with the control group,but there was signifi-cant difference ( P <0. 01 ) on MCF-7 cells by HCS. Conclusions The most effective component formula from the active ingredients of Salvia Miltiorrhiza and Panax Ginseng have a strong inhibition of proliferation and induction of apoptosis to resist breast cancer with selection, and there is no significant difference in MCF-10A cells.

High content screening analysis for systematic study on traditional Chinese medicine / 中草药

High content screening(HCS) analysis is an advanced technique in the era of systematic biology,which can comprehensively reflect the changes of cell with live,dynamic,and multiparametric characters.It is a good tool to study the complex ingredients and mechanism of traditional Chinese medicine(TCM).Application of the technique would contribute to the discovery of effective ingredients,elucidation of mechanism,and development of TCM theory.
