This study demonstrates that the combination of Alhagi maurorum and Amygdalus haussknechtii with docetaxel has synergistic antitumor effects on 4T1 breast cancer cells, inducing apoptosis and regulating gene expression of HIF-1alpha and FZD7. Amygdalus haussknechtii has acceptable antitumor activity but shows limited efficacy in combination with docetaxel.
Medicinal plants have long been studied due to their anticancer effects and use of them is commonly increased as a complementary and alternative medicine (CAM therapies) among patients with cancer. In this study, Alhagi maurorum (A.m) and Amygdalus haussknechtii (A.h) extracts were evaluated for their effects on inhibiting the growth of 4T1 breast cancer cells. Based on MTT assay results, the IC50s of A.m and A.h extracts were 57 mu g/ml and 85 mu g/ml, respectively. Then the cell migration, gene expression, and degree of apoptosis after 48 hours in each treated group with A.m and A.h extracts alone or in combination with docetaxel (DTX) on 4T1 cells were evaluated. A.m had a synergistic behavior with DTX (CI < 1). A.h reduced DTX IC50 but presented CI > 1. Cell migration assay showed that each extract alone or in combination with DTX prevented the migration of 4T1 cells. The Ao/EB staining and flowcytometry results confirmed that, in combination therapy, A.m + DTX and A.h + DTX induced apoptosis close to the level of DTX. Real-time PCR analysis showed that A.m + DTX (IC50 + IC25) downregulated the mRNA expression of HIF-1 alpha and FZD7. A.m + DTX (IC50 + IC10) group decreased the expression of HIF-1 alpha. Moreover, in A.h + DTX (IC50 + IC25) group, beta-Catenin and FZD7 were downregulated and upregulated, respectively. Generally, our findings suggest that the combination of A.m and DTX possesses synergistic antitumor effects on 4T1 cells, which may be a valuable choice for CAM therapies. A.h has an acceptable antitumor activity but not in combination with DTX.
