Fig. 4From: Extract from Astragalus membranaceus inhibit breast cancer cells proliferation via PI3K/AKT/mTOR signaling pathwayAnalysis of cell apoptosis induced by AM extract in three distinct breast cancer cell lines. Breast cancer cells were treated with 50 μg/ml of AM extract for 24 h, and cell apoptosis was assessed by flow cytometry with FITC-Annexin V/PI Staining. The data are representative of three independent experiments carried out under the same conditions. *p < 0.05, **p < 0.01, ***p < 0.001, compared with blank control group (CTRL); #p < 0.05, ##p < 0.01, ###p < 0.001, compared with DMSO groupBack to article page
