Abstract:Objective To research the inhibit proliferation and induce apoptosis effect of Yanghe Huayan Decoction combined with Trastuzumab and PI3K inhibitor (LY294002) on breast cancer cell lines SK-BR-3 (HER-2 overexpression). Methods The intestinal absorption fluid of Yanghe Huayan Decoction was prepared. The breast cancer cell lines SK-BR-3 were divided into blank control group, Chinese medicines group, Trastuzumab group, Trastuzumab + Chinese medicines group, Ly group and Ly + Chinese medicine group. The inhibitory rate of the growth of the cells at 24, 48, 72 h were observed by MTT. The changes of cell apoptosis and cell cycle at 72 h were observed by flow cytometry. Results The inhibition rate, apoptosis rate and S phase cell percentage were increased, while the G2/M phase cell percentage was decreased, in the Chinese medicine group, Trastuzumab group, Trastuzumab + Chinese medicine group, Ly group and the Ly + Chinese medicine group, compared with the blank control group, with statistically significant difference (P < 0.05). Moreover, the inhibition rate of each drug group was increased gradually with the duration of drug action (24, 48, 72 h), presenting a time dependent effect (P < 0.05). The effects of the Trastuzumab group + Chinese medicine, Ly + Chinese medicine group inhibiting cell proliferation, inducing apoptosis and cell cycle arrest were better than those of the Trastuzumab group, Ly group respectively (P < 0.05). Conclusion The intestinal absorption fluid of Yanghe Huayan Decoction can effectively inhibit cell proliferation and induce apoptosis, and the combination of Chinese medicine with Trastuzumab and LY can further inhibit cell proliferation, induce apoptosis, enhance S phase retardation, and inhibit cell entry into G2/M phase. It is suggested that there may be synergistic effect in the treatment of her-2 high expression type of breast cancer by the combination of warming Yang and dispersing masses herbs with Trastuzumab and PI3K inhibitor.
