Effects of cardamonin on glucose uptake capacity in human triple negative breast cancer MDA-MB-231 cells
Objective:,2,To investigate the effects of cardamonin on the glucose uptake capacity in human triple negative breast cancer MDA-MB-231 cells and explore its molecular mechanism.,Methods:,2,MDA-MB-231 cells were divided into the cardamonin groups with different concentrations(0, 10, 20, 40, 80 μmol/L) .Each group was treated with cardamonin at the corresponding concentration for 24 hours.The cell viability was detected by CCK-8 assay.The glucose uptake capacity was evaluated by 2-NBDG assay.The mRNA expressions of glucose transporters(,GLUT,) were detected by PCR.The protein expressions of GULT were detected by Western blot.MDA-MB-231 cells were subcutaneously inoculated to construct tumor bearing nude mice model.After intraperitoneal injection of cardamonin(0.3, 1.0, 3.0 mg/kg) for 4 weeks, the breast cancer tissue of tumor bearing mice was isolated, and the expressions of GLUT proteins in the breast cancer tissue were detected by Western blot.,Results:,2,Cardamonin(20, 40, 80 μmol/L) significantly inhibited the viability of MDA-MB-231 cells in a dose-dependent manner(,P,<,0.01), and cardamonin at concentration of 20 μmol/L significantly reduced the glucose uptake capacity of breast cancer cells(,P,<,0.05) .Further studies showed that, cardamonin at concentration of 20 μmol/L significantly down-regulated the mRNA expressions of ,GLUT3, and ,GLUT4, in breast cancer cells(,P,<,0.01) .Cardamonin at concentration of 40 μmol/L significantly down-regulated the protein expression of GLUT3 in breast cancer cells(,P,<,0.01), cardamonin(10, 20, 40 μmol/L) significantly down-regulated the protein expression of GLUT4 in breast cancer cells(,P,<,0.01), but showed no obvious effect on GLUT1 protein expression(,P,>,0.05) .Cardamonin(0.3, 1.0, 3.0 mg/kg) significantly reduced the protein expression of GLUT1 in breast cancer tissue of tumor bearing mice(,P,<,0.01), while cardamonin(1.0, 3.0 mg/kg) significantly down-regulated the protein expression of GLUT3(,P,<,0.01) .,Conclusion:,2,Cardamonin may decrease the cell viability and glucose uptake capacity of human triple negative breast cancer MDA-MB-231 cells by down-regulating the mRNA and protein expressions of GLUT.
