Tumors were excised on day 15 and analyzed. Tumor microvessel density(MVD)was assessed by immunohistochemical staining of CD34;and expression of vascular endothelial cell growth factor(VEGF), the mitogen-activated protein kinases p38 mitogen-activated protein kinase(MAPK), extracellular signal-regulated kinases 1 and 2(ERK1/2), and Jun N-terminal kinase(JNK)and their phosphorylated forms were assessed by Western blotting.RESULTS: Treatment with cisplatin caused a significant loss of body weight compared with controls,whereas Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) extract combinations had no effect. Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) significantly decreased tumor weight and tumor MVD compared with controls,and at the 3∶1 treatment group had similar efficacy to cisplatin in reducing MVD. Tumors from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) treatments also showed decreased p38 MAPK, p-p38 MAPK, ERK1/2, p-ERK1/2,JNK, and p-JNK expression compared with the control group(all P < 0.01). VEGF protein expression was significantly reduced in the 2∶1 and 3∶1 treatment groups compared with the control group(P < 0.01).CONCLUSION: Extracts from Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) hindered LLC growth in the xenograft mouse model, possibly via inhibition of the MAPK signaling pathway, VEGF production, and tumor angiogenesis.展开更多

MTS assay was applied to analyze the effect of the component formula ofHuangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Curcumae Phaeocaulis) on A549 cells viability in various uniform design groups. A549 cells with exponential growth in routine culture were exposed to Co Cl_2(200 μmol/L) to mimic hypoxic conditions. Group 0 was treated with RPMI-1640, the group Co Cl_2 was treated with Co Cl_2(200 μmol/L),the group DDP + Co Cl_2 was treated with 4 mg/L Cisplatin injection(DDP) + Co Cl_2(200 μmol/L), and the drug group was treated with various dose of E(0.5 E, 1 E, 2 E) + Co Cl_2(200 μmol/L). All groups were cultured for 24 h. Cell apoptosis was measured by Annexin V-FITC/propidium iodide double staining and flow cytometry. Western blot assay and quantitative real-time polymerase chain reaction(q RT-PCR) were employed to detect the protein and m RNA expression of B-celllymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax) and cysteinyl aspartate specific proteinase-3(caspase-3).RESULTS: The E obtained by the uniform design was comprise of 200 mg/L Astragalus polysaccharide(X1) and 32 mg/L Curcumin(X3). Group DDP+Co Cl_2, group 1 E + Co Cl_2 and group 2 E + Co Cl_2 promoted the apoptosis of A549 cells(P < 0.05). Group1 E + Co Cl_2 and group 2 E + Co Cl_2 had no statistically significant differences compared with the group DDP + Co Cl_2(P > 0.05). Compared with group 0, various doses of E + Co Cl_2 could up-regulate the expression of Bax and caspase-3 and down-regulate the expression of Bcl-2 at protein and m RNA levels(P < 0.05).CONCLUSION: Astragalus polysaccharide and Curcumin was the optimal combination of Huangqi(Radix Astragali Mongolici) and Ezhu(Rhizoma Cur-cumae Phaeocaulis). E promoted the apoptosis of A549 cells. Combination of Astragalus polysaccharide and Curcumin increased the expression of Bax and caspase-3, and decreased the expression of Bcl-2 to initiate apoptosis in A549 cells under chemical-induced hypoxia.展开更多
